This study compared three types of RAS nurseries for shrimp: biofloc (BF), clear-water (CW), and hybrid RAS (HY). Results showed that differences between treatments in terms of shrimp survival, mean harvest weight, specific growth rate, and feed conversion ratio were
The authors recently performed a study to evaluate immunity to white spot syndrome virus and virulent Vibrio parahaemolyticus in shrimp treated with a new mineral extract additive in pelletized feeds.
The project produces specific-pathogen-free broodstock with good reproductive performance, fast growth and high survival. More than 60 hatcheries in India have received broodstock from the program.
The authors conducted studies to test the performance of young shrimp postlarvae in systems with different approaches to aeration and water handling. Proactive management through proper feed applications and water quality control were critical elements.
While intensive shrimp farms in Australia and elsewhere are sensitive to rising energy prices, global intensification and farming innovations have led to significant improvements in shrimp farm energy efficiency. Important among the changes was the global switch to zero-exchange production
There is a clear difference between the shrimp postlarvae traits that are economically important in Central and South America versus those of Asia, creating a challenge for breeders to satisfy the somewhat opposing breeding goals the regions demand.
The Shrimp Book, published in 2010, brings together experts from around the world to fill the critical need for a central reference source on the state of shrimp production practices.
In a challenge test under controlled conditions using a severe strain of the virus, resistance to WSSV was shown in shrimp supplied by the Camaronera de Coclé, S.A. L. vannamei genetics program.
A study evaluated Pacific white shrimp given plant protein-based diets with varied lipid content and soybean meal:soy protein concentrate ratios.
