Teleosts lack a hypophyseal portal system and hence neurohormones are carried by nerve
fibers from the preoptic region to the pituitary. The various cell types in the teleost pituitary …

The ability to fully control sexual maturation and spawning and to produce large numbers of
high quality seeds 'on demand'(ie all year long) is a primary requirement for the successful …

Oogenesis in fishes follows a universal plan; yet, due to differences in the synchrony and
rate of egg development, spawning frequency varies from daily to once in a lifetime. Some …

In many cultured fish species, particularly in those new for aquaculture, unpredictable and
variable reproductive performance is an important limiting factor for the successful mass …

Recently, the importance of the female to population dynamics—especially her non‐genetic
contribution to offspring fitness or maternal effect—has received much attention in studies of …

Broodstock diet formulations are essential for the development of marine fish breeding and
propagation. Japanese research has mainly focused on red sea bream (Pagrus major) …

As increasing amounts of novel raw materials are used in aquafeed production, it is
important to measure their quality against existing ingredients and their effects upon …

The induction of triploidy and gynogenesis by chromosome set manipulation has
traditionally been studied more intensively in freshwater than in marine fish. In the last years …

The effects of the polyunsaturated fatty acids (PUFAs), arachidonic acid (AA),
eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and prostaglandins (PGs) on …

We investigated the effect of dietary n− 3 highly unsaturated fatty acids (n− 3 HUFA) on egg
and larval quality in the Japanese flounder Paralichthys olivaceus. Diets with similar …
