TL;DR: Examination of factors that can critically affect fecundity, egg production, egg quality, spawning time, and maintenance of egg supplies examines aspects of brookstock management central to determining total number of eggs produced, quality of eggs, and timing of maturation and spawning.

TL;DR: Vitellogenesis is identified as the period in the maturation during which EFA are incorporated most effectively into the developing oocytes in European sea bass.

TL;DR: High levels of mortality in Pacific oysters Crassostrea gigas in the Republic of Ireland were recorded during the summer of 2009 and the new variant of Ostreid herpes 1 (OsHV-1 μVar) which first emerged in France in 2008 was identified from affected stocks.

TL;DR: In this article, the sperm of broodstock sea bass fed either a commercial pelleted diet or fed ‘trash fish’ were compared with sperm from wild fish, and the results showed that the results from the wild fish and broodstock fed commercial diet were generally very similar, but the fish fed a commercial diet had elevated 20:5 n − 3 and decreased 20:4 n − 6 reflecting the fish oil component of the diet.

TL;DR: Accelerated seasonally-changing and “square-wave” (direct change from short to long day) photoperiods advanced the timing of potential S1 (1+) and S2 (2+) smolts by a maximum of 3 and 7 months respectively and showed an increased post-smolt maturation.
