Life cycle ofCorophium insidiosum (Crustacea, Amphipoda) in laboratory culture
The age of the mother animal at the time of breeding proved to be of particular importance: Individuals from early broods have an apparently longer life span than those originating from late broods, and they have more moults, mostly a higher growth rate, higher number of brood, higher total number of offspring, and, surprisingly, also a longer period of incubating their broods.

Salinity was found to be the prominent factor controlling the abundance of gammarid amphipods, followed by temperature and dissolved oxygen, and representatives of the families Arnpeliscidae, Gammaridae and Photidae are negatively correlated with salinity.
The Arabian Sea: Physical environment, zooplankton and myctophid abundance

The Arabian Sea is one of the most productive regions of the world oceans. This productivity mainly results from coastal and open ocean upwelling in summer and cooling effects during winter. Earlier…

The results suggest that unilateral eyestalk ablation can be resorted to accelerate growth and conversion efficiency in penaeid prawns especially in juvenile forms especially in their physiology related to growth.
Experimental studies on the life cycle ofJassa falcata (Crustacea, Amphipoda)
Jassa falcata (Leach), an unselective suspension feeder, was cultivated in standing, unaerated finger bowls, feeding on a mixture ofBrachionus plicatilis, Scrippsiella faeroense, Ulva spec., and…
