The outbreaks caused by Vibrio spp. are a notable threat to the potential growth of economy penaeid culture, which is still controlled administration antibiotics. At first, infected group was subjected phenotypic bacteriological examination with subsequent molecular identification via 16S rRNA gene sequencing, confirmed four strains spp., V. atlanticus, natriegens, alginolyticus, and harveyi, f...

The objective of this work was to compare the morphometry of hatchery‐reared and wild‐caught mangrove crab (Ucides cordatus) megalopae. Ten U. cordatus megalopae of each group (hatchery‐reared and wild‐caught) were individually analyzed using a stereoscopic microscope equipped with an ocular micrometer. Length, width, and height of all megalopae were measured, and the size of body appendices wa...

Despite identification of multiple factors mediating salmon survival, significant disparities in survival-to-adulthood among hatchery- versus wild-origin juveniles persist. In the present report, we explore the hypothesis that hatchery-reared juveniles might exhibit morphological defects in vulnerable mechanosensory systems prior to release from the hatchery, potentiating reduced survival after...

We have documented an early life survival advantage by naturalized populations of anadromous rainbow trout Oncorhynchus mykiss over a more recently introduced hatchery population and outbreeding depression resulting from interbreeding between the two strains. We tested the hypothesis that offspring of naturalized and hatchery trout, and reciprocal hybrid crosses, survive equally from fry to age...

Chitosan, a natural biopolymer composed of a linear polysaccharide of α (1-4)-linked 2-amino 2-deoxy β-D glucopyranose was synthesized by deacetylation of chitin, which is one of the major structural elements, that forms the exoskeleton of crustacean shrimps. The present study was undertaken to prepare chitosan from shrimp shell waste. The physiochemical properties like degree of deacetylation ...

The study has been focused on effect of untreated distillery effluent (Devans Breweries Ltd., Jammu) on germination of gobi sarson (Brassica napus. L. var. Punjabi Special). Six treatments (E0.... E100) each having three replicates were made. E0 was taken as control in which tap water was used for irrigation of the plants. For E20, E40, E60, E80 and E100, different concentrations i.e. 20, 40, 6...

The large land area requirement of constructed wetlands (CWs) is a major limitation of its application especially in densely populated and mountainous areas. This review paper provides insights on different strategies applied for the reduction of land area including stack design and intensification of CWs with different aeration methods. The impacts of different aeration methods on the performa...
