The culture of yellow tang represents a considerable economic opportunity and critical conservation strategy in coral reef ecosystem protection. The Oceanic Institute is working to establish aquaculture techniques to reduce the capture of wild fish.
Zebrafish offer a living model system for research in a wide variety of scientific disciplines. The Aquatic Resources Program at Children’s Hospital Boston recently identified an alternative feeding method that requires less labor.
In a study, tilapia were fed fish oil- or vegetable oil-based diets for five months, then switched to a fish oil finishing diet for three months. Growth and feeding efficiencies were not significantly compromised.
Although not universally practiced, the potential benefits of selective breeding in aquaculture outweigh all other options for improving animal performance. The genetic potential of aquaculture animals is plastic and can be improved over a relatively short timeframe.
A large-scale integrated shrimp aquaculture park (iSHARP) project in Malaysia is approaching completion of its first phase. Biosecurity is a priority at iSHARP. The design of each unit allows individual modules or ponds to be “locked down” to prevent disease from spreading.
A study evaluated the effects of two organic acid blends on performance, gut health and disease resistance in olive flounder. The dietary organic acids were effective in lowering total gut bacterial counts, gut Vibrio counts and in conferring resistance against Edwardsiella tarda.
A study conducted to investigate the effects of encapsulated and non-encapsulated phytogenics derived from plants on the performance and antioxidant status of farmed rainbow trout.
The authors used Ichthyophthirius multifiliis (ich) and fluorescent-tagged Edwardsiella ictaluri to examine whether parasites vector bacteria into fish.
Consumer perceptions regarding seafood influence consumers’ willingness to consider and purchase fish as a viable protein choice.
A significant correlation was established between ovarian fluid pH of stripped eggs and subsequent hatch of hybrid catfish eggs.
Arapaima, also known as pirarucu or paiche, offers appealing flesh color and texture, low fat content and high levels of protein and fatty acids.
After a decade of research, Korea has produced individual glass eels for Japanese eel aquaculture. Despite dependence upon the wild seed, Japanese eel aquaculture production has been growing significantly and comprises over 27 percent of Korea’s freshwater aquaculture.
Development of integrated aquaculture systems could assist in improving environmental quality and changing public perceptions of aquaculture.
The establishment of land-based recirculating systems for cobia could expand production of the species. The authors, who demonstrated cobia are well suited for culture in tanks, conducted a study to compare the performance of cobia reared at different densities.
The quality of postlarvae supplied by a shrimp hatchery can vary considerably. Common myths, such as acceptance of low survival and insufficient concern for water quality, can contribute to lower animal quality.
A project of the Soy-in-Aquaculture program evaluated the feasibility of using soy protein concentrate and soybean meal to replace fishmeal in cobia diets.
