To address the issue of overfishing, sustainability and its effect on marine fishers' income, this study was taken up in Mumbai, India. Greater Mumbai was studied at micro level. Primary data on capital costs, operating costs and returns to mechanized fishing were collected. Secondary data on marine fish landings, landings from the trawlers and tot...

Demand for marine fish is a function of availability and practically enjoys inelastic demand in Mumbai. This paper examines the catch sustainability-income paradox that negates real income improvements of fishers in Maharashtra in the long run. The income scenario of the marine fishers in Maharashtra has not been too encouraging. Rise in prices hav...

Diveagar Beach, located in Raigad District of Maharashtra stretches across 4 kilometres in length and at the northern end, small rivulets enter the sea. The surf clam Mactra violacea Gmelin, 1791 forms sustenance fisheries along the beach, providing livelihood to bivalve fishers. M. violacea burrow in subsurface layer and prefers sandy and silty ha...

Marine debris is a major global pollution threat having direct and indirect impact on marine and coastal environments, biodiversity, dependent community and their health etc. It has been affecting the fisheries sector in several ways especially in developing countries, which doesn't have much waste management practices or awareness on marine debris...

The Potential Fishing Zone (PFZ) advisory generated using satellite-based remote sensing data is a boon to the marine fisher folk and usefulness of it in fishing activity is increasing progressively. ESSO-INCOIS is the nodal agency to provide the PFZ advisory on daily basis with specific reference to 586 fish landing centers along the Indian coast....

Automatic Identification System (AIS) is a significant development in navigation safety since the introduction of RADAR. It was originally developed as a collision avoidance tool for commercial vessels to improve the helmsman’s information about his surrounding environment. AIS does this by continuously transmitting a vessels identity, position, sp...

Despite high potential and significance in domestic as well as international market, the ornamental fish trade remains an unorganized sector in the country. Nevertheless, the coordinated effort of the stakeholders offers enough scope for new avenues for horizontal and vertical expansion of the ornamental fish sector in India. Henceforth, it is esse...

The present study has been done in three hotspots areas of ornamental fish production and trade in India Viz. Kolkata (West Bengal), Chennai and Mumbai. The sociometric study revealed that the ornamental fishery is a male oriented activity in all the three study locations, but it holds as primary occupation only in case of Chennai. Moreover, it has...

A characteristic shore seine fishery is practised along southern Maharashtra, Goa and northern Karnataka region mainly for catching Indian mackerel Rastrelliger kanagurta. The mackerel shoals occurring close to shores during post monsoon season from November to January are spotted by the experts among the fishing community and caught with the shore...

Geographical information system (GIS) is an invaluable decision support tool, designed to address spatially related problems for management of natural resources. The power of GIS lies in its ability to visualise and relate various types of geo-referenced spatial and non-spatial data allowing users to analyse them. In India, use of GIS in fisheries...

Danio aequipinnatus (30 to 40 mm size) were collected from their natural habitats in an around Guwahati, Tejpur and Itanagar (North- East India) and brought to Central Institute of Fisheries Education (CIFE), Mumbai. The acclimatized and matured fishes were reared in 50× 25× 25 cm glass aquaria. Overall six different sets were arranged for captive...

A 60 day study was conducted to evaluate the impact of different timings of aeration during night hours between 18.00-24.00 h, 21.00-03.00 h and 24.00-06.00 h on growth, survival and production performance of rohu (Labeo rohita) fingerlings against a control with no aeration, in 50 m 2 outdoor concrete tanks (10 m×5 m×1.3 m). L. rohita fry were sto...

In the present study, endeavor was been made to document the different types of traditional fish aggregating devices (FADs) being practiced by the fishermen from the study area and to explore the fishers’ rationale behind their use. Looking into the nature of the study, the information was collected by personal interviews, field observations and co...

Central valley region of Manipur harbours great ichthyofaunal diversity; diverse fisheries resources, thus uses wide array of fishing methods which are evolved traditionally and being practiced extensively throughout the central valley. Some of the practices are unique to certain area such as the Loktak lake. The different traditional fishing metho...

A study was conducted for 60 days to delineate the individual and combined effect of dietary Mannanoligosaccharide (MOS) and Bacillus subtilis (BS) supplementation on growth and immune status of Labeo fimbriatus fingerlings. Results illustrated that the inclusion of MOS alone did not significantly (P>0.05) improve the overall growth compared to TC....

A 60 days growth experiment was carried out to evaluate the effect of dietary cod liver oil (CLO) replacement with palm oil (PO) on the growth, survival and muscle proximate composition of the Indian Major Carp, Cirrhinus mrigala. The experimental design consists of four distinct treatment groups viz. T1 (75% CLO+25% PO), T2 (50% CLO+50% PO), T3 (2...

Impact of varied durations of aeration on growth, survival and production performances of catla (Catla catla), rohu (Labeo rohita), fringe lipped carp (Labeo fimbriatus) and olive barb (Puntius sarana) were evaluated in outdoor concrete tanks (10 m×5 m×1.3 m) during fingerlings rearing. At a combined stocking density of 0.5 million fry/ha, provisio...
