The present study evaluated the potentiality of cage culture stinging catfish (Heteropneustes fossilis) under different feeding regimes. Fish experiments were consists three treatments (T1, T2 and T3), each with replicates, lasted for 90 days. stocking density was 300 fry (~1.5 g) per cage. given commercial floating feed (28% crude protein) twice daily (in morning evening) at 5% (T1), 7% (T2) 9...

Site selection is a key factor in any aquaculture operation, affecting both success and sustainability. Moreover, it can solve conflicts between different coastal activities, making a rational use of the coastal space. Geographical information systems (GIS) have become of increased significance for environmental planning and assessment mainly because of the need to compare a great number of spa...

Real and perceived aquaculture environmental impacts that must be considered prior to expansion to open ocean locations include: 1) benthic carbon loading, 2) water column nutrification, 3) stimulation of harmful algal blooms, and 4) escapement and implications to wild populations. A simulation model was developed for predicting the benthic impacts from offshore cage culture. The model simulate...

To investigate the potential of extensive net cage culture for Nile tilapia (Oreochromis niloticus) fingerlings, an experiment was conducted in net cages suspended in a fertilized pond. Mixed-sex population of Nile tilapia with an average initial body weight of 0.065 g was used to stock in experimental cages. Four treatments; non added-substrate without supplemental feeding (NSNF), non added-su...

haemato-biochemical studies in rainbow trout infected with saprolegnia were carried out under temperate climatic conditions of kashmir valley to find out the variation in blood parameters. the trial was carried out on 405 cultured rainbow trout fish ranging in length from 47.8 to 69.8 cm and in weight from 1300 to 1920 g. the same experiment was carried out on 2,70000.00 trout fish eggs from no...

Ship aquaculture platforms are expected to become a meaningful way expand offshore farming. The growth performance and nutritional composition of the large yellow croaker reared in an ship system nearshore traditional cage was evaluated this study. results showed that could effectively avoid harsh environment such as typhoons red tides. test adapted culture short time. No serious stress events ...

Cage fish farming in Indian reservoirs has the potential to enhance reservoir production manifold. The present study estimated that around 14,000 cages have been installed different of country which are producing 16% current production. Around 7.5 lakh mandays labour being generated by cage country. An empirical state Jharkhand State found adoption culture contributed 30% livelihood fishers. no...

The body tilt angle of a fish has a large effect on the acoustic target strength. For an accurate estimation of fish abundance using acoustic methods, it is necessary to measure body tilt angles in free-ranging fish. We measured diurnal body tilt angle distributions of threeline grunt (Parapristipoma trilineatum) while swimming in schools in a fish cage. Micro-acceleration data loggers were use...
