Abstract

The development of gamete manipulation and conservation is penaeid shrimp may have important effects in breeding programs. Artificial insemination makes it possible to obtain unbiased estimates of genetic parameters under current hierarchical mating designs. The use of factorial mating designs coupled with external or in vitro fertilization may allow more accurate estimates of genetic parameters and the presence of maternal effects, as well as design selection programs with higher genetic responses, decreased levels of loss in genetic variability and lower inbreeding levels. In turn, the conservation of semen may be useful in reducing loss of genetic variation in conservation programs, measuring genetic gains without control populations, and facilitating the use of foreign germplasm and the design of crossbreeding programs.
