Genetic diversity and differentiation of cultured Nile tilapia populations from Ethiopia revealed by ddRAD-seq: implications for better hatchery management
Published in Aquatic Living Resources (2025-01-01)“…Nile tilapia aquaculture in Ethiopia is dominated by small-scale fish farming in ponds, with seeds from poorly managed hatcheries and wild sources. Hence, the development of aquaculture in Ethiopia faces a major hurdle owing to the absence of good-quality seeds, largely because of the lack of genetic management practices within hatchery centers. …”

Identification of critical points of thermal environment in broiler production
Published in Brazilian Journal of Poultry Science (2010-03-01)“…Environmental temperature and relative humidity were the critical points identified in the hatchery and in both farms. The classes determined as critical control points in the broiler houses were poultry litter, feeding, drinking water, workers' hygiene and health, management and biosecurity, norms and legislation, facilities, and activity planning. …”

Egg quality markers in domesticated broodstock of Atlantic halibut (Hippoglossus hippoglossus) with relevance for optimization of hatchery protocols
Published in Frontiers in Aquaculture (2025-09-01)“…The percentage of normally developing embryos at blastopore closure 81 ± 18% (41–99%) was the strongest predictor overall and was significantly associated with both survival until hatching and hatching success.DiscussionSurvival until hatching and the proportion of embryos with successful blastopore closure can both serve as egg quality indicators, offering potential enhancements to commercial hatchery management practices.…”

Age at release affects developmental physiology and sex-specific phenotypic diversity of hatchery steelhead trout (Oncorhynchus mykiss).
Published in PLoS ONE (2025-01-01)“…Most steelhead trout hatcheries increase growth rate during rearing to produce and release yearling smolts for harvest augmentation, but natural steelhead exhibit variable age of smoltification, so this common rearing practice may not be ideal for programs focused on recovering imperiled wild stocks; therefore, it is important to investigate and compare alternative hatchery rearing methods that promote life history diversity. …”
