Cholecystokinin and Trypsin Responses of Larval Red Drum (Sciaenops Ocellatus) to Soluble Components of Rotifers (Brachionus Plicatilis) and Algae (Isochrysis Galbana) por Webb, Ken, Holt, Joan

“…While there are a number of other labs alsoinvestigating CCK and other digestive hormones such as bombesin, PPY, and gastrin; research into the roles of thesehormones in fish is still in its infancy. Previous research with red drum larvae suggests that some component ofrotifers and algae enable red drum larvae to more efficiently utilize microparticulate diets than when these are notincluded in the culture system. …”

Nutrition and Feeding of the Brazilian Pink Shrimp Farfantepenaeus paulensis por O. Cavalli, Ronaldo, C. Abreu, Paulo, Wasielesky, Wilson

“…In recent years, however, renewed interest in the farming of the pink shrimp Farfantepenaeus paulensis insouthern Brazil has been stimulated by its market value and higher tolerance to comparatively low temperature levels.F. paulensis proved relatively easy to rear through the larval stages but juveniles reared in ponds perform poorly onformulated feeds, usually displaying low growth rates. …”

Characterization of Insulin-Like Peptides and Their Relation to Molt and Metabolism of the Shrimp Litopenaeus vannamei por Gutiérrez, Ana, Nieto, Julie, Pozo, Francisco, VandenBosch, Luc, Van Soest, Sofie, Schoofs, Liliane

“…On the basisthat common biological function may be related to a similar structure, we searched for an insulin-related substance inthe shrimp Litopenaeus vannamei and further investigated its function. An IGF-I-like molecule was detected inneurosecretory cells of the brain and thoracic ganglion in shrimps at different molt stages. …”

Worldwide Fish Meal Production Outlook and the Use of Alternative Protein Meals for Aquaculture por W. Hardy, Ronald.

“…This development was the result of increased demand from theaquaculture industry coupled with recent global fish meal production significantly lower than the 15-year average. Itis likely that fish meal prices will remain higher than the normal price range for the foreseeable future, resulting inhigher use level of conventional alternative protein sources as well as those that, until recently, have been tooexpensive to consider in aquafeeds. …”
