The many challenges of disease management in aquaculture
Regardless of the aquatic species an aquaculture venture produces, there are significant risks to su...
The sea urchin, Strongylocentrotus intermedius, is an important cultured species in China. Results from previous selective breeding studies have suggested interactive effects of genetics and culture practices. Zhang et al. (2019), in a 10-month growout trial conducted under commercial, sea-water conditions, found evidence of significant family by stocking density interactions on growth, suggesting that greater attention should be paid to these effects.
Early maturation of Atlantic salmon raised in land‐based, closed containment water recirculation aquaculture systems has created economic challenges and spurred research efforts to identify appropriate management strategies. Yossa et al. (2019) review the current literature on early maturation in Arctic char, offering useful insights on knowledge gaps and research directions that have important implications for commercial production of this species.
Yellowtail amberjack Seriola lalandi are a valuable marine fish for which aquaculture technology has made considerable advances. Reducing disease losses in the hatchery phase would reduce fingerling costs. Garcia-Mendoza et al. (2019) present the first report on bacteriological quality in recirculating aquaculture systems (RAS) for this species, contributing to understanding of disease management for this species and in land-based RAS.
Development of efficient aquaculture methods for cleaner species used to control sea lice is critical to the Atlantic salmon net pen industry. Little is known of the basic reproductive biology of corkwing wrasse, Symphodus melops, principal cleaner fish species. Gonzalez et al. (2019) describe the embryonic development and effects of temperature on egg viability of this species, contributing to commercial efforts to culture cleaner fish for the Atlantic salmon industry.
