Developing a plant-based diet for Cobia Rachycentron canadum
Aquaculture reached a landmark in 2009, supplying greater than half of the total fish and shellfish for human consumption (Naylor et al. 2009). With global fisheries in decline and human population increasing, the gap between protein supply and protein demand is widening. Aquaculture must continue to expand to meet these growing needs, and it must do so in a safe, sustainable manner that decreases the world’s reliance on harvesting fish for fishmeal while still producing a high quality product. There are several difficult hurdles the aquaculture industry now faces if this needed growth is to occur.

The Ginger Shrimp - Metapenaeus kutchensis: a promising species for shrimp aq...International Aquafeed
India earned US$ 2.67 billion through the export of marine products in 2010-11. About 60 percent of it came from shrimp production. The annual estimated average landing of shrimps from the fishery in India during 2008-10 was 0.4 million tonnes of which 60 percent were contributed by penaeid shrimps. An additional 0.15 million tonnes was produced from aquaculture. EXPERT TOPIC 1503: Cobia
Everyone wants to be in on the next big thing, be that a speculative share, a new technology gadget and yes, even a new fish!
Krill Meal
Krill meal was evaluated as a replacement for fishmeal and other costly ingredients in feeds for Litopenaeus vannamei. Juvenile shrimp were fed diets with varying levels of krill meal or krill oil in indoor clear water and outdoor green water tanks. Shrimp growth and survival were generally similar between diets, though green water promoted higher growth. Diets with krill meal and krill oil provided 12-23% higher profits compared to fishmeal-based diets. Krill meal was found to fully replace fishmeal and soy lecithin without negatively impacting shrimp performance.
Chef Robby Goco - Sustainable Ingredients and Menu Innovation
This document discusses the history and evolution of food systems from prehistoric times to the present. It notes that for most of human history until the 19th century, people were hunter-gatherers or grew their own food locally. In the early 20th century, commercialization led to food being transported over long distances. Today, people can access food from anywhere at any time. The remainder of the document outlines strategies for more sustainable and health-promoting food systems, such as buying local and seasonal whole foods, reducing red meat and processed foods, and being transparent about sourcing.

India - Aqua feeds and feeding trends
In aquaculture production India is the second largest country in the world after China. The terrestrial and aquatic animal farming sectors are rapidly expanding and intensifying in the country. Aquaculture, which counts for almost two thirds of fish production in India, has shown significant growth in the last two decades and has transformed itself into an industry contributing substantially to food production.
SEED PRODUCTION OF COBIA
This document provides information on the historical development and current practices for seed production of cobia. Some key points:
- Cobia aquaculture research began in the 1970s, with successful captive spawning first achieved in the 1990s in the US and Taiwan. By the 2000s, several US states had developed cobia hatcheries.
- In India, the Central Marine Fisheries Research Institute has led efforts to develop cobia broodstock and seed production. The first captive spawning in India was achieved in 2010.
- The production cycle involves broodstock development, induced spawning using hormones, hatchery rearing of eggs and larvae, nursery culture, and offshore cage grow-out.
Aquaculture
The document discusses aquaculture and fish feed. It notes that aquaculture is the farming of aquatic organisms through interventions like feeding and protection. It also discusses the energy requirements of fish and the key dietary requirements including proteins, lipids, carbohydrates and vitamins/minerals. The document summarizes several studies that examined replacing fish meal with plant-based proteins in fish feed and the effects on growth and economic returns. It concludes that further research is still needed but plant proteins are increasingly being used in fish feed to lower costs.
18 feeding trial-without_marine_proteins,_biofloc
The document discusses a study that produced shrimp without the use of marine proteins in their feed by utilizing a biofloc system. The bioflocs recycled waste and nitrogen in the water, complementing the pelleted feeds and allowing excellent shrimp growth with diets containing no fish meal. The biofloc system and formulated feeds enabled sustainable shrimp production with reduced costs and environmental impact.
Viral diseases in crustaceans
Viral diseases pose a major threat to crustacean farming. This document summarizes several important viral diseases affecting farmed shrimp species. Yellow Head Disease, caused by Yellow Head Virus, causes mass mortalities in Penaeus monodon. White Spot Disease, caused by White Spot Syndrome Virus, infects juveniles of many shrimp species and can cause 80-100% mortality within a week. Taura Syndrome, caused by Taura Syndrome Virus, most severely affects Litopenaeus vannamei and is characterized by reddish discoloration and lesions. These and other viruses like Infectious Hypodermal and Hematopoietic Necrosis Virus, Baculoviral Midg
Aeration management in shrimp farming
1) Mechanical aeration of shrimp ponds enhances dissolved oxygen levels and lowers nitrogenous compounds, improving production efficiency.
2) A survey of 29 shrimp farms found most used rectangular ponds of 0.5-5 hectares and stocked L. vannamei at densities of 21-50 shrimp/m^2.
3) Farmers primarily used aeration to increase yields over 3,000 kg/ha/cycle and prevent oxygen kills, with typical aeration rates of 3-5 hp/ha.
321 samocha 9 00- final_go 100 m3
This document summarizes a study on the challenge of Vibrio bacteria in high density shrimp production systems. The study tested zero-water exchange raceways stocked with Pacific White Shrimp at high densities. Water quality was maintained through aeration and biofloc filtration. The study found that Vibrio concentrations increased over time, resulting in disease outbreaks and increased mortality in both raceways. While a probiotic helped suppress Vibrio initially, it did not prevent mortality. The study demonstrates the risk of Vibrio outbreaks in intensive, biofloc-based systems and the need for better prevention and control methods.
EXPERT TOPIC 1501: Shrimp
This document summarizes research on using phytogenic feed additives to improve the health and growth of farmed Pacific white shrimp. Researchers from Kasetsart University in Thailand conducted tank trials supplementing shrimp feed with 400ppm and 800ppm of a phytogenic additive from Dr. Eckel. They found that the additive led to increased body weight gain, improved feed conversion, higher survival rates when the shrimp were challenged with Vibrio bacteria, and enhanced immune responses. The additive appeared to strengthen the shrimp's natural defenses by modulating immune cells and protecting cells in the hepatopancreas from necrosis during disease challenge. The researchers believe the additive's plant extracts and polyphenols contribute to its antioxidant,
Freshwater-prawn
The document discusses a project in Malaysia to develop a sustainable freshwater prawn industry using biotechnology to create all-male populations of Macrobrachium rosenbergii, or giant Malaysian freshwater prawn. The project aims to transform rural economies and make Malaysia a meaningful producer of freshwater prawn. Creating all-male populations through androgenic gland removal is expected to increase yields by over 60% compared to mixed populations due to males' faster growth. This could potentially generate over 1 billion ringgit annually for the Malaysian economy and support thousands of farmers.
Survey of aeration management in shrimp farming
This document discusses aerated pond management for shrimp farming. It provides information on:
- The importance of adequate dissolved oxygen for shrimp health and survival, and the factors that influence oxygen levels in ponds.
- Common types of mechanical aerators used in aquaculture ponds, including paddlewheel aerators, propeller-aspirator pumps, and diffused-air systems.
- Key findings from a survey of 140 shrimp farms on their aeration practices, including typical pond sizes, aeration rates, species cultured, and aerator positioning strategies.
- How mechanical aeration is used to supplement natural oxygen levels, improve water quality, and increase pond production capacities.

Lecture 9 crustaceans 2 shrimp and prawn
The document provides information about various shrimp species farmed for aquaculture. It details the top shrimp producing countries in 2006, with Thailand as the largest producer at 200,000 MT. Several species of shrimp are discussed, including the dominant Penaeus vannamei (Pacific white shrimp), Penaeus monodon (giant tiger prawn), and freshwater prawns of the Macrobrachium genus. The life cycle, larval stages, and farming practices for shrimp are summarized, including pond construction, stocking, feeding, and harvesting methods.
Application Of Probiotic And Molases
(1) The study found that adding probiotics and molasses to the rearing media tended to accelerate the growth stages of swimming crab larvae, increase their survival rates, body weights and carapace lengths compared to probiotics alone, though the differences were not statistically significant. (2) The combination of probiotics and molasses also better controlled the populations of pathogenic Vibrio bacteria. (3
Biofloc information
1. Biofloc technology is an aquaculture system that uses nitrifying bacteria to control water quality within culture ponds without water exchange. This allows for high stocking densities.
2. Studies show biofloc systems can yield commercial productions of 20-25 metric tons per hectare per crop cycle at stocking densities over 130-150 shrimp per square meter. Higher densities of over 150 have been tested in research trials.
3. Key factors for success include maintaining high aeration levels, proper paddlewheel placement, and biofloc control through siphoning to keep levels below 15 ml/L of water. With these the system can yield higher productions at lower costs than conventional shrimp farming.
Tilapia And Cobia Culture Trong And Son
The document provides information on techniques for tilapia and cobia cage culture. It discusses site selection for cages, including factors like water quality, current flow, and distance from pollution sources. It also covers seed stocking density and size, feeding management, health management, and harvesting methods. Cage designs commonly used for tilapia and cobia farming are described.
Applications of artificial Intelligence in Mechanical Engineering.pdf
Historically, mechanical engineering has relied heavily on human expertise and empirical methods to solve complex problems. With the introduction of computer-aided design (CAD) and finite element analysis (FEA), the field took its first steps towards digitization.

Optimizing Gradle Builds - Gradle DPE Tour Berlin 2024
Sinan from the Delivery Hero mobile infrastructure engineering team shares a deep dive into performance acceleration with Gradle build cache optimizations. Sinan shares their journey into solving complex build-cache problems that affect Gradle builds. By understanding the challenges and solutions found in our journey, we aim to demonstrate the possibilities for faster builds. The case study reveals how overlapping outputs and cache misconfigurations led to significant increases in build times, especially as the project scaled up with numerous modules using Paparazzi tests. The journey from diagnosing to defeating cache issues offers invaluable lessons on maintaining cache integrity without sacrificing functionality.
