Tag Penaeus monodon

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. 

Shrimp-breeding programs release only a small fraction of their genetic material when they sell seed to clients for grow-out. This protects their large investment in developing the stocks so clients return for their next batch of seed instead of breeding the stocks themselves. 

Polymerase chain reaction (PCR) testing demonstrated that Penaeus monodon offspring derived from founder shrimp collected from the Indo-Pacific region had genomic infectious hypodermal and hematopoietic necrosis-related DNA sequences that reacted with OIE-listed IHHN virus diagnostic primers. 

Studies by the University of Arizona Aquaculture Pathology Laboratory identified the causative agent for AHPNS as a unique strain of Vibrio parahaemolyticus bacteria that can produce toxins responsible for the primary pathology in affected shrimp. 

To meet demand and maintain the sustainability of the shrimp aquaculture industry, commercial synthetic artemia has been developed for use as a bio-secure replacement for live artemia in larviculture. 

A five-year project was undertaken in Brunei Darussalam to develop advanced technology for the production of large black tiger shrimp. A combination of technologies has enabled efficient production of large-sized black tiger shrimp, which could lead to a resurgence of this species in Asia. 

Specific pathogen-free offspring developed from founder populations of P. monodon collected from Brunei coastal waters were introduced into a biosecure breeding program, where they have been reared to the fifth generation using family-based selection for reproduction and growth. 

Male reproductive dysfunction has been increasingly reported in commercial shrimp maturation facilities. The authors recently carried out studies to characterize the reproductive capability of male black tiger shrimp. 

Outside optimal salinity ranges, aquaculture species have higher feed-conversion ratios, grow at slower rates, become stressed and susceptible to disease, or even die. 

Soybean meal is increasingly being used in aquaculture feeds due to its nutritional quality and lower cost than animal protein sources.
