Abstract
Crustacean nutritional studies, such as requirements for proteins, amino acids, lipids, fatty acids, vitamins, minerals, etc., are reviewed, concerning with the fact that the feeding requirement of crustaceans differs between species (for example, carnivorous species require feeds with high contents of protein and lipid, compared with omnivorous and herbivorous species). This information is useful in determining the optimum dietary level of some nutrients. However, little information is available on the nutritional requirements of the spiny lobster, Panulirus japonicus, in particular during the phyllosoma stage.
So far, it has been established that only Artemia and gonads of the blue mussel, Mytilus galloprovincialis, are effective as foods for phyllosoma. It is very difficult to rear phyllosoma to reach to the puerulus stage with a high survival rate, even though phyllosoma are fed these kinds of feeds. It shows a lack of information on some nutritional elements in Artemia and mussel. The aims of our studies are to search for or develop optimal foods for the phyllosomal stage of spiny lobster P. japonicus. Studies on making an artificial phyllosomal feed were started with checking the size, softness, leaching, etc. of the artificial feed by rearing phyllosoma. Seasonal variations in proximate compositions of gonad of blue mussel were also monitored.
This paper provides useful information in preparing the artificial feed for phyllosoma stage of spiny lobster.
