The Marine Conservation Society (MCS) works on several programs to protect UK seas including fisheries management, reducing marine pollution, and monitoring marine species and habitats. Through their Beachwatch program, over 110,000 volunteers have collected litter data along UK coastlines. This data has helped pass policies like single-use plastic bag bans. MCS also runs a citizen science diving program called Seasearch that collects species and habitat records to help identify and manage marine protected areas. The document describes a case study where MCS used a community engagement method to facilitate stakeholder workshops on managing the Kingmere Marine Conservation Zone off the Sussex coast.

Freshwater mussels are an important part of river ecosystems but many species are endangered. Mussels play key roles like filtering water and providing habitat. They are very sensitive to pollutants like ammonia and were among the most sensitive species considered in setting the 2013 US EPA ammonia standard. This standard will better protect mussels and other aquatic life in Missouri waters, though it may apply broadly across the state given mussels' widespread historical distribution. Cooperation will be important to successfully implement the new protective standard.

The document summarizes data collected by volunteers from two streams, Delaware Creek and Coffee Creek, in Oklahoma. The volunteers measured physical habitat, collected fish and macroinvertebrates, and tested water chemistry. Delaware Creek had higher quality physical habitat and biological communities than Coffee Creek, indicating it is in better condition. Both streams are compared to a reference for their ecoregion.
This document summarizes a study comparing the abundance, diversity, and stable isotope signatures of benthic fauna between mangrove, seagrass, and sand flat habitats in Gazi Bay, Kenya. Replicate cores were taken from each habitat and analyzed. Mangrove and seagrass meadows had higher densities of benthic fauna than sand flats, and seagrass showed the highest species diversity. Stable isotope signatures ranged widely but showed no direct evidence that macrobenthic species consumed mangrove or seagrass tissues. Most species appeared to feed non-selectively on microalgae and seagrass detritus. Polychaete density and diversity varied between sampling stations,

- The document investigates the relationship between scuba diver behavior and coral health by studying diver behavior at reef sites in Malaysia. Questionnaires and observations were used to examine diver contacts with coral before and after an environmental briefing. The results showed diver contacts decreased significantly after the briefing, with improvements in buoyancy, positioning, and keeping fins away from coral. Certain diver attributes like experience and buoyancy control were also correlated with behavior. The study provides recommendations to reduce diver impacts and protect coral reefs.

Grand Lake St. Marys water quality update & The Fishes of Grand Lake St. Marys presented by Wright State University-Lake Campus' Dr. Stephen Jacquemin at the April 2021 Lake Improvement Association membership meeting. https://lakeimprovement.com
This document summarizes an agent-based model of Atlantic salmon migration in Scottish coastal waters. The model uses data on salmon movements to simulate individual salmon searching for their home rivers along the coast. Initial results show the model can replicate some patterns from historical tagging studies. Further refinement is needed by incorporating more accurate estimates of river productivity and fishing effort data to improve matching with real data patterns. The next steps aim to test the model under different scenarios to better understand salmon migration behaviors.

Terrapin trends in Jamaica Bay-fall 2018 Task Force Presentationecowatchers
This document summarizes research on diamondback terrapin populations in Jamaica Bay over 20 years. Key findings include:
1) Adult female survival has declined at one nesting site since Hurricane Sandy but has remained stable at another site.
2) Over 15% of females exhibited major shell injuries that reduced their survival rate.
3) The populations show high site fidelity but some turtles move between sites temporarily.
4) Ongoing research uses GPS transmitters to track turtle movement patterns in real-time.
NYC Dep oyster reef update regarding head of bay oyster projectecowatchers
This document provides an update on the DEP Oyster Research and Restoration Project in Jamaica Bay. The project aims to evaluate factors affecting native oyster growth and survival, assess ecosystem services from oyster restoration like water quality benefits and habitat use, and understand oyster recruitment to establish a self-sustaining population. A donor system with adult oysters releases larvae into the water column. Receiver reef beds were constructed and monitored, but no oyster spat has been detected yet on spat collectors. Diver surveys and plankton tows were conducted to monitor the project.
Science Forum Day 1 - Eric Baran - Fisheries and dam development in the Mekon...WorldFish
The document discusses fisheries and dam development in the Mekong Basin. It notes that the Mekong supports the world's largest inland fishery, providing over 2 million tonnes of fish annually, which is a critical source of food and protein for millions of people. However, the large number of proposed mainstream dams would likely block long-distance fish migrations, threatening the fisheries. A strategic environmental assessment recommended deferring decisions on mainstream dams for 10 years to study impacts, but one dam project has moved forward despite objections.
This document summarizes a study that used environmental DNA (eDNA) to detect the presence of mudpuppies (Necturus maculosus maculosus) along the St. Clair-Detroit River System. The study sampled eDNA from four sites with varying mudpuppy trapping success. Initial results were inconclusive due to inconsistencies. Ongoing eDNA sampling is being integrated with additional samples and protocol adjustments to better understand mudpuppy occupancy. Local habitat restoration appears important for mudpuppy conservation in occupied areas of this degraded river system.
This document outlines the programme for a two-day workshop on developing a sustainable finfish aquaculture industry in England.

It summarizes progress on habitat restoration efforts, but also notes some significant losses of populations. Climate change poses challenges for coastal populations that are isolated in streams. Several dam removal and habitat improvement projects aimed at helping trout are discussed for specific streams. Population monitoring data from various streams is presented. Continued protection of habitat and restoration efforts will be important for preserving these wild brook trout resources.
C2.03: Identifying essential fish habitats using oceanographic process - Grin...Blue Planet Symposium
The Cushing's triangle on fish migration explains various life cycle activities from recruitment to fishing as governed by physical oceanographic processes. The role of currents in a closed area such as Gulf of Kachchh (GoK) and geological structures such as mounts in an open area such as Mangalore coast is explored to see the role of fish aggregation creating fishing and nursery grounds. Numerical and particle transport models was used for generating hydrodynamics and further for identifying areas of fish aggregation. Validations of the models were done with insitu observations. Likelihood retention areas of larval aggregations indicated formation of nursery grounds. <br />Oceanographic processes such as fronts, eddies, meanders, rings etc and primary productivity linked to them are keys to identification of Potential Fishing Zones (PFZ). Altimeter satellite remote sensing data could identify mesoscale features (Eddies). Such data products can supplement the SST-Ocean color based PFZ and provide information in cloudy conditions too. Data collected from 454 commercial fishing trips in the Andaman Sea along with maps of sea level anomaly and Moderate Resolution Imaging Spectroradiometer (MODIS) global level 3 mapped thermal IR daytime sea surface temperature (SST) from Aqua and Terra satellite were used for the study. <br />Productive habitats and their vulnerability can also be assessed using the satellite data based oceanographic processes. The paper looks into the various case studies carried out in tropical marine conditions.
Abstract: Different kinds of fishing gears used along the Ulhas River estuary (URE) were studied for their make and methods of operation. Most of the gears were designed indigenously to suit the availability of the amenable fishery species. The overall chronospatial pattern of frequency of gears operation was obtained using PRIMER v6 software. The use of gears was most frequent and diverse towards the lower reaches of the estuary. Late post-monsoon season was the most affluent in gear frequency. The important fishing methods used along the URE was ‘vana’ (barrier net), ‘busa’ (surface gill-net), ‘dol’ (stationary bag net) and ‘malli’ (basin method for capturing mudskippers on mud-flats). The fishing was carried for subsistence or artisanal levels at major while commercial fishing was highly reduced in URE. The reduced mesh sizes of the ambient gears portray the size of the species sought which depicted the threatening status of overall condition of fisheries in URE and requires a special attention for its rejuvenation.

Using telemetry data, researchers studied steelhead smolt survival through Puget Sound to identify causes of low survival. Telemetry tags on smolts from the Green and Nisqually Rivers showed lower survival for hatchery fish and those with longer migrations. Analysis of encounters between tagged smolts and seals fitted with receivers indicated that seals were a potential predator and some smolts stopped moving, suggesting predation had occurred.
This document summarizes a case study examining the potential impacts of dredging the entrance to the Lower Myall River on migratory shorebirds. It finds that dredging could negatively impact shorebirds through increased disturbances from recreational boating and dredging activities. Over 32 migratory shorebird species and 10 Australian resident shorebird species use the area, including globally significant populations of Eastern Curlew and Bar-tailed Godwits. The document recommends referring the proposal to the Commonwealth Government and conducting species impact statements on three threatened shorebird species. It discusses addressing concerns about unnecessary environmental reviews through scientific evidence and consultation with experts.
This document summarizes research on coastal cutthroat trout populations in South Puget Sound, Washington. It finds that coastal cutthroat trout in the region:
1) Support important sport fisheries but have declined due to overharvesting historically.
2) Have an "unknown" status due to limited data, variable life histories, and lack of baseline information.
3) Appear stable based on initial index surveys and acoustic tagging research that found low mortality rates and limited movement outside of South Puget Sound. More long-term research is still needed to understand population trends.
There were 82 coastal drowning deaths in Australia during 2009-2010, a decrease from the previous year but still above the five-year average. New South Wales saw the highest number of deaths with 39 cases. Males accounted for 80% of victims and the most common age group was 40-49 years old. Over half of all drownings occurred at beach locations, with swimming/wading and fishing from rocks or beaches being the most common activities. Most deaths happened in the afternoon hours of 4-5pm or on weekends. Many victims lived over 50km from the location they drowned.

This document outlines a study examining the factors influencing sea otter populations and coastal ecosystems along the Pacific coast. The study will use multiple approaches, including remote sensing, watershed modeling, health assessments, diet analysis and population monitoring to analyze how ocean productivity, watershed inputs, contaminants and disease affect sea otters and the nearshore environment from Alaska to California. Results will provide insights into managing threats and recovering sea otter populations.
The document analyzes coastal processes at Southern Palm Beach on the Gold Coast of Australia. Fieldwork and analysis found the beach is wave-dominated and highly dynamic, changing morphology frequently. Seasonal storms and tropical cyclones increase risks like beach erosion and flooding during peak tourism season. Due to unpredictable beach conditions, erosion hazards, and high maintenance costs, the document recommends against constructing a resort at the proposed site. A location further south near Currumbin Creek may be more suitable due to higher elevation and sediment accumulation.

The Sea-Run Brook Trout Coalition is a non-profit organization established in 2011 to protect and restore populations of sea-run brook trout and their coastal habitat. The organization coordinates various restoration projects in streams across Massachusetts, Connecticut, and New York, including habitat restoration, population monitoring through electrofishing and PIT tagging, and brook trout reintroductions. The Coalition also works to purchase and protect important habitat areas and has leveraged over $6.9 million for land protection in key streams.
This document summarizes Southern California Edison's marine mitigation program for the San Onofre Nuclear Generating Station. It describes the station's once-through cooling system and its impacts on marine life, including entrainment of fish eggs and larvae and effects on the nearby kelp forest. As required by the Coastal Commission, SCE established a mitigation program that included constructing 150 acres of artificial reef habitat and 150 acres of tidal wetlands to compensate for these impacts. The program also included studies of the station's fish return system and long-term monitoring. SCE has spent over $172 million on the mitigation program to date with additional ongoing monitoring costs.
Water Worries -- Nitrogen From Septic Tanks, Fertilizer, Poor Sewage Treatmen...Save The Great South Bay

This document examines factors affecting fish entrainment at the massive water diversions of the State Water Project and Central Valley Project in the San Francisco Bay Delta estuary. It analyzes 13 years of data on fish salvage counts, pumping operations, and environmental characteristics to determine what factors influence entrainment of different fish species. Entrainment of migratory pelagic species like delta smelt, longfin smelt, and striped bass was found to correlate with their seasonal occurrence near the export facilities. Flow patterns through the estuary also predicted pelagic fish entrainment. Entrainment of resident demersal species and littoral species was not clearly linked to diversion flows. The study suggests manipulating hydrodynamics
This study investigated how different shoreline structures influence fish behavior. Researchers found that:
- Fish moved and schooling more around more structurally complex rock sill habitats compared to simpler bulkheads or natural marshes.
- The number of fish passes was highest and schools largest around rock sills, suggesting they provide more refuge than other structures.
- Habitat structure, not just predator presence, influenced fish schooling behavior, with tighter schools observed near more complex rock sills.
- Living shorelines with rock sills may enhance estuarine habitats and nursery roles by providing structural complexity that influences fish movement and refuge more than traditional hardened structures.
This document summarizes a study on the rockfish resources of the south central California coast. Researchers from California Polytechnic State University placed observers on party boats from 2003-2005 to record catch data by species, including catch per unit effort and mean size. They supplemented this with historical catch data from 1980-1998 from the California Department of Fish and Game and Pacific Gas & Electric. The study aims to analyze population trends over the past 25 years for various rockfish species in the region and compare sizes over time. Preliminary results found fluctuating catch rates but no consistent declining trends, except for bocaccio rockfish. Mean sizes were generally above maturity levels.

The document discusses a pilot project to test a new mobile biofiltration system for managing stormwater runoff from Highway 7 into Ohop Creek in Washington. The system was installed in January 2022 to capture and filter runoff, collecting water quality samples during rain events to test the effectiveness of removing contaminants harmful to salmon. If successful, the relatively inexpensive and scalable system could help address a major threat to salmon recovery from increasing stormwater pollution due to growing traffic volumes. The results will inform whether wider use of the technology could help prevent harmful chemicals from polluting salmon streams.
This document summarizes a study that tracked the origins of juvenile Chinook salmon in the Nisqually River estuary using coded wire tags. The study found that most fish caught came from local Nisqually River hatcheries, but fish also originated from hatcheries in the Green, Puyallup, and Skykomish Rivers. The tagging data provides insights into the fish's migration patterns and survival rates, helping managers evaluate hatchery programs and protect wild salmon populations.
The document summarizes a study of potential improvements to Interstate 5 between Tumwater and Mounts Road in Washington. $550,000 in state and local funds were provided to identify mid- and long-term strategies to address increasing congestion in the area. The study analyzed various scenarios like operations improvements, land use changes, transit expansion, and additional lanes. Performance measures related to travel time, accessibility, and the environment were used to evaluate scenarios. Draft recommendations include prioritizing strategies like land use changes, transit expansion, and travel demand management in the short- and mid-term.

This document summarizes the objectives and approach of Melanie Davis' research on developing dynamic habitat models for estuary-dependent species. The objectives are to: 1) Model changes in restoring habitat mosaics over time, 2) Determine prey availability in each habitat type, 3) Identify prey consumed by juvenile Chinook salmon, and 4) Use a bioenergetics model to estimate habitat quality as the mosaic shifts. The research involves modeling different restoration and climate change scenarios to understand their impacts on salt marsh habitats and prey availability/consumption. Field studies are being conducted to understand prey use by salmon in different habitat types to parameterize the bioenergetics model. The goal is to provide tools to help restoration planning under

This document contains appendices to the "Nisqually Watershed Response to the 2018 Streamflow Restoration Act". Appendix B contains WAC 173-511, the Nisqually Instream Flow Rule, which establishes instream flows and surface and groundwater limitations in the Nisqually River basin to protect instream resources pursuant to state law. The rule applies waters within the Nisqually River basin and was promulgated to retain perennial rivers, streams and lakes with minimum instream flows and levels.
This document describes various mitigation strategies to increase streamflows in different sub-basins in WRIA 11. It provides details for each strategy such as the sub-basin(s) it would benefit, estimated annual water benefits in acre-feet and cubic feet per second, potential ecological benefits, and uncertainties. Some of the strategies described include connecting new developments to city water to reduce consumptive use, purchasing and retiring water rights, stream restoration projects, forest management projects, stormwater projects, and managed aquifer recharge projects. The document provides a table that summarizes the strategies and estimates their total annual water benefits could range from 2,470 to 8,623 acre-feet.
This document is an addendum to the Nisqually Watershed Management Plan that provides the watershed's response to Washington's 2018 Streamflow Restoration Act. It was prepared by the Nisqually Watershed Planning Unit with assistance from various stakeholders and state agencies. The addendum describes the watershed context and characteristics that influence mitigation alternatives to offset new domestic permit-exempt groundwater withdrawals projected between 2018-2040. It then outlines a variety of habitat restoration projects, land use strategies, and policy options that could provide ecological and instream flow benefits to help the watershed achieve no-net-loss of annual average streamflows.
The document is a planning unit agreement to update the Nisqually Watershed Management Plan per the mandate of ESSB 6091. It establishes the Nisqually Indian Tribe as the lead agency and identifies participating governmental and non-governmental entities. The scope is to estimate impacts of new permit-exempt domestic wells through 2040, identify appropriate mitigation, and develop an addendum to the 2003 watershed plan by February 2019. The agreement sets ground rules for consensus-based decision making and open public participation in the planning unit.
- A study analyzed land use and habitat changes in the lower Nisqually River valley over the past 60 years using aerial imagery from 1957, 1980, and 2015.
- Between 1957 and 1980, riparian forest decreased by 7.7% due to conversion to agriculture. From 1980 to 2015, riparian forest increased 2.3% within a restoration area.
- Upland forest saw minimal loss between 1957-1980 but declined 8.2% between 1980-2015 due to land development.
- Overall forest cover in the study area decreased 8.6% from 1957-1980 and another 5.9% from 1980-2015 through land development, agriculture, and river channel movement.

This document summarizes efforts to evaluate biodiversity in the Salish Sea at the population level. It describes studying the genetic structure of populations to better understand how different populations may respond differently to environmental changes. Examples discussed include studying eelgrass and Olympia oyster populations to inform conservation efforts, and chum salmon populations to inform management. The document also describes a project using Autonomous Reef Monitoring Structures to study cryptic and understudied species diversity at different sites, finding varying numbers of species and individuals across sites. Studying population diversity is important for conservation, management and education.
This document outlines 8 habitat restoration projects proposed along the Nisqually River in Washington. Project 1 requests $290,710 to protect 60 acres and 0.5% of the flood zone at river mile 33. Project 2 requests $469,844 to acquire 90 acres for future restoration and protect 12.7% more floodplain. Project 3 requests $510,000 to continue removing levees and restoring natural areas along the Wilcox Reach.

Microbial characterisation and identification, and potability of River Kuywa ...Open Access Research Paper
Water contamination is one of the major causes of water borne diseases worldwide. In Kenya, approximately 43% of people lack access to potable water due to human contamination. River Kuywa water is currently experiencing contamination due to human activities. Its water is widely used for domestic, agricultural, industrial and recreational purposes. This study aimed at characterizing bacteria and fungi in river Kuywa water. Water samples were randomly collected from four sites of the river: site A (Matisi), site B (Ngwelo), site C (Nzoia water pump) and site D (Chalicha), during the dry season (January-March 2018) and wet season (April-July 2018) and were transported to Maseno University Microbiology and plant pathology laboratory for analysis. The characterization and identification of bacteria and fungi were carried out using standard microbiological techniques. Nine bacterial genera and three fungi were identified from Kuywa river water. Clostridium spp., Staphylococcus spp., Enterobacter spp., Streptococcus spp., E. coli, Klebsiella spp., Shigella spp., Proteus spp. and Salmonella spp. Fungi were Fusarium oxysporum, Aspergillus flavus complex and Penicillium species. Wet season recorded highest bacterial and fungal counts (6.61-7.66 and 3.83-6.75cfu/ml) respectively. The results indicated that the river Kuywa water is polluted and therefore unsafe for human consumption before treatment. It is therefore recommended that the communities to ensure that they boil water especially for drinking.

Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...Joshua Orris
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.
Improving the viability of probiotics by encapsulation methods for developmen...Open Access Research Paper
The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.

Evolving Lifecycles with High Resolution Site Characterization (HRSC) and 3-D...Joshua Orris
The incorporation of a 3DCSM and completion of HRSC provided a tool for enhanced, data-driven, decisions to support a change in remediation closure strategies. Currently, an approved pilot study has been obtained to shut-down the remediation systems (ISCO, P&T) and conduct a hydraulic study under non-pumping conditions. A separate micro-biological bench scale treatability study was competed that yielded positive results for an emerging innovative technology. As a result, a field pilot study has commenced with results expected in nine-twelve months. With the results of the hydraulic study, field pilot studies and an updated risk assessment leading site monitoring optimization cost lifecycle savings upwards of $15MM towards an alternatively evolved best available technology remediation closure strategy.

38. Telemetry Summary
Low early marine survival rates consistent with SARs and abundance of Puget Sound steelhead
Instantaneous daily mortality rates are high (i.e., mortality occurs very quickly)
Rapid travel times (1 – 3 weeks from river mouths to ocean entry)
Puget sound may serve more a migratory corridor than a rearing environment
Has it always been this way, or is that part of the problem?
Hood Canal and Puget Sound steelhead exhibit different patterns
Central Puget Sound may represent a mortality hotspot

• Temporal and spatial overlap: concurrent pings on same fixed
(moored) receivers
• Potential encounters: pings detected on mobile (seal-mounted)

• Putative predation events:
• recurring continuous pings on seal-mounted receivers,
perhaps followed by...
• Stationary tags (defacated tags) connected to seal
movements/locations
52. Puget Sound Chinook salmon
• Residency in Puget Sound = weeks to years.
• Very abundant in Puget Sound spring through
summer (Beauchamp and Duffy 2011, Rice et al. 2012)
• Spring/summer growth rate and body size strongly
correlated with survival (in hatchery stocks: Duffy and Beauchamp
2011)
• Foraging opportunities, diet composition, and
competition (including comp. with hatchery Chinook salmon) likely
influence survival.
