Seminar Abstract

Dietary astaxanthin requirements of juvenile tropical spiny lobster Panulirus ornatus

A major focus of recent aquaculture nutrition research in Australia, has been to develop a high performance pelleted feed for the spiny lobster Panulirus ornatus. In the wild, this fast growing tropical species will reach 1 kg in size after only 18 months post-settlement making it a good aquaculture candidate. Carotenoids, in the form of astaxanthin, are a very expensive component of crustacean feeds but little is known of the requirements of this spiny lobster.

This talk discusses our experiment assessing growth, survival and tissue carotenoid levels of juvenile Panulirus ornatus. Lobsters were fed either pelleted feeds supplemented with astaxanthin or one of two fresh mussel reference feeds - green-lipped Perna canaliculus and blue Mytilus edulis. Results of this experiment are described and their implications discussed in the context of pelleted feed development for this species.
