Variations in Weight and Proximate Composition of Newly Hatched Octopus vulgaris (Cuvier 1797) Paralarvae

Survival and growth of juvenile octopi vary considerably. The objective of this research was to determine variations in weight, total lipids (TL), and total protein (TP) of newly hatched Octopus vulgaris paralarvae (0 days old) over the course of the spawning period. Newly hatched paralarvae dry wei...
