A new breeding program for genetic improvement of Indian white shrimp (Fenneropenaeus indicus) in Egypt was established at a private shrimp farm at AL Dibah Triangle Zone (DTZ) to develop disease-resistant shrimp for the country’s aquaculture industry.
Inbreeding commonly causes a decrease in the mean values of traits of productive interest in aquaculture. Results of a study, however, showed that inbreeding had no effect on grout survival of Pacific white shrimp from 65 to 130 days of
A National Broodstock Improvement Network for aquaculture could help to break the link between inbreeding and hatchery size.
Disease problems on shrimp farms may be partly driven by an interaction between management practices that cause inbreeding in small hatcheries and the amplification by inbreeding of susceptibility to disease and environmental stresses.
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
China’s expansive tilapia culture industry is based on exotic species introduced continuously since 1956. Technical advances for improving the limited germplasm are expected to aid the industry.
The Maricultura del Pacífico hatchery in Mexico uses two-stage selection that controls the pedigree of every animal to minimize inbreeding.
