Calling for a National Broodstock Improvement Network
A National Broodstock Improvement Network for aquaculture could help to break the link between inbreeding and hatchery size.

‘Big picture’ connects shrimp disease, inbreeding
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.

Measuring real-world benefits of breeding programs
In general, benefits from genetic increases in growth rate result from better farm environments. Breeding programs should focus selection on genes expressed favorably in the environment that most affect farm profit.

Shrimp copyright: Inbreeding strategies effective against copying of genetically improved shrimp
Shrimp breeders often protect their genetic investment by selling broodstock that will accumulate increasing levels of inbreeding in successive generations.
