Selective breeding of rohu, Labeo rohita to Aeromonas hydrophila infection requires a challenge model to obtain LD50 dose and study of bacterial persistence in survivors’ tissues. Fish were bath challenged with various routes viz., only immersion, after scale removal (with and without high stocking), after skin abrasion (with and without high stocking), under only high stocking density and afte...

The following paper provides an overview of the current trends in marine fisheries, aquaculture and fish breeding, and highlights the technological innovations that occurred in the management and production of aquatic resources. The purpose of the paper is to explain the role technological innovation played in meeting the growing worldwide consumer demand for fish, and in dealing with scientifi...

ABSTRACT One of the constraints in pirarucu, Arapaima gigas farming is reproduction captivity, due to inconsistent number spawning events per reproductive cycle, thus, unreliable availability juvenile fish. This a first-hand report on predation pirarucu larvae by opportunistic fish species breeding pond. Fish samples were collected for stomach content analysis from pirarucu-breeding pond with r...

Nervous necrosis virus (NNV) could infect many economic fish species and cause the fish nervous tissue necrosis vacuolization in histopathology. Once the fish is infected with NNV, 80-100% mortality will occour in grouper breeding farm. However, the immune system does not develop completely in grouper larva. Therefore, the traditional vaccine may not be effective during larva stage. This study ...

Motile aeromonad septicemia caused by mesophilic strains of Aeromonas hydrophila is a widespread problem in cultured freshwater fish. We announce here the draft genome sequence of the multidrug-resistant A. hydrophila strain Ae25, isolated from a koi carp (Cyprinus carpio) with motile aeromonad septicemia that was collected from an ornamental fish-breeding farm in Sri Lanka.

Background Although several studies confirmed positive effects of fish oil on semen quality, the antioxidant status in omega-3 supplemented diets of several studies is a fuzzy point. The aim of this study was to investigate the effect of dietary fish oil and (or) vitamin E supplementation on cryopreserved sperm in Mehraban rams. MaterialsAndMethods Sixteen fertile rams were randomly allotted to...

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...
