Ecosystem Based Fisheries Management (EBFM) is a holistic approach that considers the complex interactions within fisheries, including impacts on fish stocks, the marine environment, and social and economic benefits. EBFM aims to balance the preservation of social, economic, and cultural benefits derived from fisheries with efforts to minimize impacts on the marine environment and fish populations. In contrast to older approaches that consider only target species, EBFM incorporates social, economic, and ecological factors into management decisions. The goal of EBFM is to maintain the health, integrity, and sustainability of the ecosystem while sustaining human needs and resource productivity.

Eco-Friendly Fishing Lures: One of the best ways to practice sustainable fishing is to use biodegradable fishing lures. Since rubber doesn’t break down, in the water or in a fish’s stomach, a good substitute is biodegradable plastic that will dissolve over time. An added perk to these eco-friendly options is that the soft lures can be made in all colors and designs to attract your target fish just as effectively as traditional lures.
Eco Fishing Weights: Not only is lead toxic to humans, but it’s dangerous for fish as well, causing both physical and behavioral changes. That’s why many manufacturers today produce sinkers made from safer materials that will cause less damage if ingested or left in the water. Some common substitutes used in non-toxic weights are brass, steel, tungsten or tin. You’ll also want to make sure they’re chip resistant to prevent paint loss in the water. And remember that while these variations may be a little more expensive than lead lures, the benefits outweigh the costs.
Eco Fishing Line: Like lures, anglers today can opt for biodegradable monofilament line fishing line that breaks down faster yet still has the same performance characteristics as regular line. Even if you don’t have biodegradable line, you can take steps to properly dispose of your traditional line to reduce your impact on the environment. For example, many bait shops, fishing access points, piers and other spots have designated collection bins for discarded monofilament and fluorocarbon fishing line.
Other Eco Fishing Tackle and Equipment: Anglers have several other eco-friendly options nowadays. For example, when you’re choosing hooks, opt for circle hooks instead of J-hooks to minimize internal damage if you’re practicing catch and release. Look for rigs made of materials like glass beads. Pick knotless nets. Instead of using fresh bait collected from fish habitats, choose artificial. And when you’re picking out other gear like waders, bags or boxes, look for those made from recycled materials.
ECO-FRIENDLY ANGLING
Beyond fishing gear, there are other ways to practice eco-friendly fishing. If you catch and release, in addition to choosing barbless circle hooks, be sure to use the right eco-friendly fishing lures for the species to avoid exhausting the fish, keep your catch wet and limit the time the fish stays out of the water to increase the chance of survival.
It’s also important to pay attention to the area around you. Take your trash with you to prevent fish and other wildlife from eating or getting caught in your rubbish. If you’re boating, consider rowing or paddling a canoe rather than a motorized choice. If you do go in a power boat, be careful when you’re navigating over fragile habitats and be careful to prevent fuel spills.

Freshwater and coastal aquaculture development can benefit from internal and external experience for preventing environmental damage and for avoiding harmful effects of degradation on aquaculture resources. Strategies to compensate for the loss of aquatic fauna (e.g. due to physical obstructions) are directly linked to important environmental issues, such as the transfer of exotic species, the spread of diseases and loss of genetic diversity, eutrophication, impairment of aesthetic qualities and the disruption of indigenous fish stocks.
There presently, conceptual frameworks for aquatic environment management backed by legal and administrative tools to create or enforce ration systems for water management, land use or fisheries and aquaculture development strengthened by adaptive institutionalization.

Abstract
Aquaculture will continue to grow as the expected fish demand will increase inevitably with the
rising population. The reliance on aquaculture systems comes with responsibility of owners and
respective stakeholders to assure that the systems are using sustainable and environmentally
friendly mechanisms. This report discusses various ways to create a more sustainable and
environmentally friendly aquaculture system in terms of fishmeal alternatives, built-structure
types, and antibiotics and chemical usage to give recommendations to fish farm owners. The
report also touches on ethical practices in owning an aquaculture system. The most sustainable
3
method was found to be feed using microalgae and insects, structure type of pen and cage, and
phage therapy as an antibiotic treatment replacement.
1.0 Introduction: Background of Aquaculture Systems
1.1 Current Unsustainable Aquaculture Methodology
With the world’s increasing in population, fish and seafood in general has become widely relied
on as a source of protein, and this reliance will continue and grow. In 2030, it is expected that
150 to 160 million tons of fish will be consumed (“Global and regional food”, n.d.). Besides
fishing, aquaculture is a major method in which we obtain fish, and will continue to be to meet
the world demand of fish. Aquaculture is diverse in its methods, but the main idea is to create a
farm in a body of water to efficiently produce copious amounts of seafood like fish (freshwater
and saltwater), and shellfish. Many factors go into an aquaculture system to assure its success,
such as the feed type, the farm location, and the farm structure. Many may assume that
aquaculture would decrease pressure on fisheries because fish are being separately farmed for the
purpose of eating, however this is not the case. Currently “Around 85% of global fish stocks are
over-exploited, depleted, fully exploited or in recovery from exploitation” (Vince, 2012). This is
greatly concerning as it is known that the global population is only increasing, and therefore the
global demand for fish consumption will only increase as well..
A mangrove is a shrub or small tree that grows in coastal saline or brackish water. The term is also used for tropical coastal vegetation consisting of such species. Mangroves occur worldwide in the tropics and subtropics, mainly between latitudes 25° N and 25° S. The total mangrove forest area of the world in 2000 was 137,800 square kilometres (53,200 sq mi), spanning 118 countries and territories.

Environmental and Social Risks and Solution Criteria in Offshore Aquaculture ...IJERA Editor
Aquaculture is a sector that involves agricultural activities aiming to meet the increasing animal food demand, contribute to balanced and healthy diet and reduce the hunting pressure on natural fish stocks. In aquaculture activities in sea, producers who are aware of the major role of obtaining an ecological balance in production regard coast utilization and environmental management as a part of production. Therefore, determination of environmental factors in production activities is highly important for sustainable aquaculture. The present study aims to determine the environmental risks and solution criteria in offshore aquaculture systems in Turkish seas. Environmental and social risks in production are collected under the main headings comprising nutrient and waste load in water, feeding, overuse of antibiotics and chemicals, fish escape, diseases, working conditions and common areas; solution criteria are collected under the main headings comprising ecosystem, water management, feed properties, legal procedure, chemical use, field management and occupational health and safety.

(May 29th, 2024) Advancements in Intravital Microscopy- Insights for Preclini...Scintica Instrumentation
Intravital microscopy (IVM) is a powerful tool utilized to study cellular behavior over time and space in vivo. Much of our understanding of cell biology has been accomplished using various in vitro and ex vivo methods; however, these studies do not necessarily reflect the natural dynamics of biological processes. Unlike traditional cell culture or fixed tissue imaging, IVM allows for the ultra-fast high-resolution imaging of cellular processes over time and space and were studied in its natural environment. Real-time visualization of biological processes in the context of an intact organism helps maintain physiological relevance and provide insights into the progression of disease, response to treatments or developmental processes.
In this webinar we give an overview of advanced applications of the IVM system in preclinical research. IVIM technology is a provider of all-in-one intravital microscopy systems and solutions optimized for in vivo imaging of live animal models at sub-micron resolution. The system’s unique features and user-friendly software enables researchers to probe fast dynamic biological processes such as immune cell tracking, cell-cell interaction as well as vascularization and tumor metastasis with exceptional detail. This webinar will also give an overview of IVM being utilized in drug development, offering a view into the intricate interaction between drugs/nanoparticles and tissues in vivo and allows for the evaluation of therapeutic intervention in a variety of tissues and organs. This interdisciplinary collaboration continues to drive the advancements of novel therapeutic strategies.
The increased availability of biomedical data, particularly in the public domain, offers the opportunity to better understand human health and to develop effective therapeutics for a wide range of unmet medical needs. However, data scientists remain stymied by the fact that data remain hard to find and to productively reuse because data and their metadata i) are wholly inaccessible, ii) are in non-standard or incompatible representations, iii) do not conform to community standards, and iv) have unclear or highly restricted terms and conditions that preclude legitimate reuse. These limitations require a rethink on data can be made machine and AI-ready - the key motivation behind the FAIR Guiding Principles. Concurrently, while recent efforts have explored the use of deep learning to fuse disparate data into predictive models for a wide range of biomedical applications, these models often fail even when the correct answer is already known, and fail to explain individual predictions in terms that data scientists can appreciate. These limitations suggest that new methods to produce practical artificial intelligence are still needed.
In this talk, I will discuss our work in (1) building an integrative knowledge infrastructure to prepare FAIR and "AI-ready" data and services along with (2) neurosymbolic AI methods to improve the quality of predictions and to generate plausible explanations. Attention is given to standards, platforms, and methods to wrangle knowledge into simple, but effective semantic and latent representations, and to make these available into standards-compliant and discoverable interfaces that can be used in model building, validation, and explanation. Our work, and those of others in the field, creates a baseline for building trustworthy and easy to deploy AI models in biomedicine.

3. Fisheries Management
Fisheries management aims to achieve the optimal
and sustainable utilization of the fishery resource
for the benefit of humankind whilst safeguarding the
ecosystem. Modern fisheries management is based on
scientific information that is used to develop the
rules under which the fisheries operate.
4.
5. Ecosystem Based Fisheries
Management (EBFM)
Ecosystem-based management aims to maintain
ecosystems in a healthy, productive, and resilient
condition so they can provide the services humans
want and need. In the fisheries sector, this approach is
referred to as ecosystem-based fisheries
management—or EBFM.
6. An ecosystem-based approach to fisheries
management addresses human activities and
environmental factors that affect an ecosystem,
the response of the ecosystem, and the outcomes
in terms of benefits and impacts on humans.
Human activities include commercial and
recreational activities from which coastal communities
derive income, pleasure, and cultural identity.
Human benefits and impacts can also include non-
consumptive values arising from nature watching, or
the value that an inland resident may place on
knowing that an ecosystem is healthy.
7. Ecosystem Based Fisheries
Management (EBFM)
Ecosystem Based Fisheries Management (EBFM) is an approach
to fisheries management that takes a holistic overview of all
ecosystem elements related to fisheries – including impacts on
stocks, marine environments, social benefits, and heritage.
EBFM acknowledges and accounts for the complex interactions
that take place within fisheries by:
Considering the social and economic benefits arising from fisheries,
such as food provision, employment, and cultural heritage.
Considering a broad range of ecological factors that may be
mitigated or exacerbated by fisheries management decisions.
Balancing the preservation of social and economic benefits with
efforts to minimize foreseen impacts on fish stocks and the wider
marine environment.
8. How is EBFM different from other
approaches to Fisheries
Management?
9. Single Species approach
The oldest formal approach to fisheries
management. Single Species focuses on the
management of target species only, taking into
account catches, biology, and population
dynamics. Though it remains the most commonly-
used approach to practical species management,
the approach has been widely critiqued for ignoring
the many and inevitable effects of ecosystem
processes, for example, predation by other species,
and temperature fluctuations.
10. Ecosystem Approach to Fisheries
Management (EAFM)
Another approach to fisheries management has been
to explicitly include ecosystem processes in the
management of one or more species, and to be
precautionary in management measures – often
termed the Ecosystem Approach to Fisheries
Management (EAFM). While this move towards
greater awareness of overarching ecosystem effects is
encouraging, EAFM does not account for social
aspects of fisheries welfare, which – under EAFM –
are often left to policy-level decisions and rarely
considered in scientific processes.
11. This is where EBFM comes in.
Perhaps a little confusingly, different countries and
bodies involved in fisheries management sometimes
use EAFM to refer to the EBFM approach. However, the
key thing that sets EBFM apart from EAFM is that it also
incorporates social and economic elements, from both
the fishery and beyond, bringing their consideration firmly
into the realm of analysis and facilitating their relevance
within management decisions. It is this that makes EBFM
the most holistic approach there is to fisheries
management.
12.
13. Need of EBFM is to solve
Marine pollution drainage, sewage, eutrophication and
subsequent oxygen depletion from aquaculture as well as sea
food companies.
Gear loss and ghost fishing
Over exploitation
Release excess nutrients (Nitrates, phosphorus) as well as
contaminants (Polychlorinated biphenyls(PCBs), mercury,
dioxin), radioactive wastes, oil, antifouling paints(tributyl
tin)
Blast fishing
Excessive trawling sea bed was disturbed
Poor selectivity, bycatch and discards
Dumping human pathogens (Cholera, salmonella), plastic
14. The goal of ecosystem-based
fisheries management
To maintain ecosystem health, integrity and sustainability.
Protect the productive potential of the system other than
protecting an individual species or stock as a resource.
Sustainability means restore those degraded parts of the
ecosystem
Make decision regarding balancing human needs with
resource productivity requirements.
The ecosystem approach also recognizes the complexity
and uncertainty in predicting responses to management
actions
15. Goals
Species sustainability keeping biomass levels above
levels where recruitment could be affected
Ecosystem sustainability ensuring that any impacts on
ecosystem structure and function are kept at
acceptable levels optimize the economic benefits to
the community
Optimize the social amenity (i.e Non-economic
benefits) derived by the community minimize the
social impacts and negative attitudes associated the
management of these resources.
20. Conclusion
Ecosystem-based fisheries management is a holistic
approach that recognizes all the interactions within an
ecosystem rather than considering a single species or
issue in isolation.
Ecosystem-based fisheries management is an
approach that tries to manage an ecosystem's structure
and function and nurtures and cultivates ecosystem
services for humanity.
