1. 1. Embryos of the viviparous embiotocid fishes develop free within the ovarian cavity from small eggs for approximately 6 months. The biochemical composition of ovarian fluid was determined and compared to serum constituents in three embiotocid sp

1. 1. Plasma and liver metabolites were measured in goldfish after 3 weeks acclimation to one of four different photoperiod-temperature regimes (16L/8D-22°C; 16L/8D-13°C; 8L/16D-22°C; 8L/16D-13°C) during September and April. Samples were taken at

Previous evidence has demonstrated a relationship between the pineal organ and carbohydrate metabolism in goldfish Carassius auratus. Pinealectomy in this species causes a decrease in liver-glycogen stores, disappearance of the diurnal variation in l
