Influence of conditioning diet and spawning frequency on variation in egg diameter for Greenlip abalone, Haliotis laevigata.

From: Journal of Shellfish Research | Date: April 1, 2006| Author: | Copyright information

ABSTRACT Both nutrient provisioning of eggs, during development within the ovary, and egg diameter are believed to be important factors governing the development and survival of invertebrate larvae. The diet of female broodstock and the conditioning regimen are likely to influence these parameters. In this study we examine the effect nf broodstock diet (three formulated diets differing in levels of the fatty acid, Arachidonic acid [ARA], and a red seaweed diet) and spawning frequency on egg diameter variability both within a batch of eggs spawned from one female and between ...
