The eggs of three deep-sea pandalid shrimps Heterocarpus abulbus, H. hayashii and H. sibogae are successfully hatched in the laboratory. The first zoeal stage of these shrimps are described, with those of H. abulbus and H. hayashii being reported for the first time. First zoeae of different Heterocarpus species can be distinguished by the spination at the anteroventral carapace, body size, rost...

The aim of the present study is to represent an annotated checklist of the Branchiopoda (Crustacea) reported from Chilean inland waters. Only Anostraca and Cladocera are found in Chile, while there are no reports on Notostraca and "Conchostraca". Our checklist contains 85 valid taxa, among which nine anostracans and 76 cladocerans. Such "low" biodiversity of the branchiopods in Chile is in real...

In the study, we were investigated effect of bioactive coating composed of quince seed mucilage (QSM) incorporating green tea extract(GTE) on oil and water content, lipid oxidation, texture, color and sensory evolution of shrimp after deep-fat frying. For this purpose, different concentration of GTE (0-20%) was blended to obtain five coating solutions (QG 0-4). We observed a significant effect ...

Vitamins are vital for normal growth and survival of living organisms and they are distributed in feedstuffs in small quantities. This review is focused on the liposoluble vitamins (A, D, E and K) in the diets and metabolic responses of the Argentine penaeoid shrimps Pleoticus muelleri and Artemesia longinaris, distributed along the South American coast line. Growth, survival and histological a...

Several immune-related molecules in penaeid shrimps have been discovered, most of these via the analysis of expressed sequence tag libraries, microarray studies and proteomic approaches. These immune molecules include antimicrobial peptides, serine proteinases and inhibitors, phenoloxidases, oxidative enzymes, clottable protein, pattern recognition proteins, lectins, Toll receptors, and other h...

Although among the less conspicuous members of the tropical shallow reef fauna, the caridean shrimps are not less abundant. Much scope for further study on the marine carideans of Indian waters still exists and many species must certainly remain to be discovered. Although, the recent checklist on prawn fauna of Indian waters reports 285 species of caridean shrimps (including fresh water forms) ...

Yellow head virus infects cultured shrimps and causes severe mortality resulting in a great economic loss. Haemolymph injection of dsRNA(pro) corresponding to the protease motif of YHV genome resulted in a complete inhibition of YHV replication. The effect of dsRNA lasted for at least 5 days. Injecting sequence-unrelated dsRNA(gfp) or dsRNA(TSV-pol) also resulted in an inhibition of YHV replica...

Cooperative breeding systems are characterized by nonbreeding helpers that assist breeders in offspring care. However, the benefits to offspring of being fed by parents and helpers in cooperatively breeding birds can be difficult to detect. We offer experimental evidence that helper effects can be obscured by an undocumented maternal tactic. In superb fairy-wrens (Malurus cyaneus), mothers bree...
