For the first time the entire sequence of the mating behaviour of Antarctic krill (Euphausia superba) in the wild is captured on underwater video. This footage also provides evidence that mating can take place near the seafloor at depths of 400-700 m. This observation challenges the generally accepted concept of the pelagic lifestyle of krill. The mating behaviour observed most closely resemble...

Since 1993, massive mortalities have occurred among the penaeid shrimp Penaeus orientalis cultured in Korea. The major gross findings of the naturally occurring cases were 2 to 6 mm sized white spots on the inside of the carapace and reddish discolorization. Amphophilic to basophilic intranuclear inclusion bodies were readily observed in the epithelia of epidermis, foregut, gills, and lymphoid ...

Shrimps are an extremely good source of protein, yet are very low in fat and calories, making them a very healthy choice of food. The present was investigated the variation between the proximate and mineral compositions of the shell and flesh of Penaeus indicus. Shrimps were collected from the Vellar estuarine environment Southeast coast of India. The results of proximate composition shows that...

The hemocyanin of the tiger shrimp, Penaeus monodon, was investigated with respect to stability and oxygen binding. While hexamers occur as a major component, dodecamers and traces of higher aggregates are also found. Both the hexamers and dodecamers were found to be extremely stable against dissociation at high pH, independently of the presence of calcium ions, in contrast to the known crustac...

Farmers of Bangladesh like to stock wild post-larvae (PL) Black tiger shrimp (Penaeus monodon). However, PL collection is detrimental aquatic biodiversity, and the supply hatchery sufficient. The study was conducted in Cox's Bazar, Bangladesh, compare quality aspects terms size variation, survival, tolerance, morphology.

Phylogenetic relationships among all described species (total of 5 taxa) of the shrimp genus Penaeus, were examined with nucleotide sequence data from portions of mitochondrial gene and cytochrome oxidase subunit I (COI). There are twelve commercial shrimp in the Iranian coastal waters. The reconstruction of the evolution phylogeny of these species is crucial in revealing stock identity that ca...
