It is a rheophilic fish species that can thrive in a wide range of ecological and climatic conditions. Globally snow trout is now a 'threatened' species. Invasion of its natural habitats by exotic trouts, river valley hydropower projects as well as destructive fishing in the Himalayan region have long been attributed to the vulnerability of this species. The intrinsic characteristics of snow trout also make it a weak competitor in the Himalayan rivers. Climate change coupling with above mentioned threats poses a new challenge for Himalayan fish, especially snow trout, as it is confined to the Himalaya. Given these threats, an intense drive for snow trout conservation is urgently required. This contribution is an attempt to find out solution to this fact. In line with the opinions of ecologists and conservationists, we suggest a few measures like setting up free-flowing and undammed rivers as 'fish conservation zones', environmental flow to downstream areas of existing dams, prohibition of stocking of exotic fish species in natural habitats and use of hatcheries for stocking and restocking of snow trout in the rivers for the conservation of the species.

The present study is the first attempt to evaluate the qualitative and quantitative effects of crab depredation on marine gillnet fishery. Experimental gillnetting was conducted onboard F V Sagar Harita from February 2017 to January 2018 along the south-west Indian coast. Depredation by the deepsea swimming crab Charybdis smithii caused intentional discard of Indian mackerel (17.59%), kawakawa (14.77%), shrimp scad (10.74%) and horse mackerel (10.02%). Financial loss due to depredation was high for Indian mackerel (19.99%), followed by shrimp scad (19.17%), kawakawa (14.77%) and horse mackerel (14.16%). A total of ₹2554.30 per operation was lost due to crab depredation. C. smithii showed a preference towards scombrids (Indian mackerel and kawakawa) over carangids (shrimp scad and horse mackerel) due to the inherent flavour and texture of scombrids.

Due to the importance of trawl fisheries along the Ratnagiri coast of Maharashtra, the present comparative study was undertaken on single and multiday trawl fishing in the region. In this study, monthly variations in fishing depth, catch per hour (CPH), discard per hour (DPH), spatio-temporal species distribution and spatial prediction of catch-discard of 136 trawl hauls were analysed. Single and multiday trawlers were operated from 15°53’24’’N to 18°00’36’’N latitude and 72°55’55’’E to 73°25’48’’E longitude within a depth range of 10 to 64 m in the Arabian Sea. For the multiday trawlers, maximum CPH of 68.30 kg h-1 was recorded in October 2015, while single day trawlers recorded CPH of 42.70 kg h-1 in November 2015. Average DPH for multiday and single day trawlers were recorded as 7.66 and 3.84 kg h-1 respectively. The study found that CPH and DPH were significantly (p<0.05) higher in multiday trawlers than single day trawlers.

However, the scope of the reservoirs in India is yet to be explored for its full fisheries potential and the scientific/management personnel are engaged in bridging the yield gap. This paper reviews the research progress made in Indian reservoir fisheries from 1998 to 2019 as a case and compares with global studies using bibliometric indicators extracted from the Web of Science (WoS) database. A total of 7607 papers published globally, mainly by the USA (2662 papers), Brazil (874 papers), and People’s Republic China (678 papers) were considered. India produced 162 publications (2.13% of total papers) during the period mainly authored by research institutes of Indian Council of Agricultural Research (ICAR). The predominant research subjects both globally and in India were ‘Environmental Sciences, Ecology, Marine and Freshwater Biology, and Fisheries’, though the composition varies. The trend in the reservoir research output indicated a shift towards applied research such as spatial planning and cage culture which offers scope for the international scientific fraternity to collaborate with Indian counterparts to solve common researchable issues. Indian authors have collaborated with 29 countries on various researchable issues, and preferred Indian journals for publications. The reservoir research in India is mainly funded by public sources and the extent of work carried out on a particular geographical area depends on the nearness to laboratories and availability of the infrastructure. This study advocates that creation of research network at pan-India level in collaboration with international partners would benefit the reservoir fisheries research in the future. This analysis including the trend and dynamics of Indian reservoir fisheries portrayed as a case study would aid in prioritising research efforts for the development of the sector in India and elsewhere.

Electron Beam Irradiation (EBI) is a non-thermal processing technique used to preserve the nutrient value and shelf-life extension of food products. In the present study, the effect of electron beam irradiation on the quality of tilapia fish chunks was evaluated. Tilapia fish chunks were vacuum packed and exposed to 0, 2.0, and 4.0 kGy doses of electron beam irradiation and kept under chilled storage. Biochemical, microbiological, and sensory qualities were analysed for up to 41 days. pH (6.85 to 7.10), total volatile base nitrogen (TVB-N), peroxide value (PV) and thiobarbituric acid (TBA) content showed an increasing trend during storage. It was observed that TVB-N content was lower in the irradiated sample than control. Thiobarbituric acid reactive substances (TBARS) values were within the acceptable limits during storage. Microbiological analysis revealed that irradiated fish chunks had lower total plate count, Pseudomonas count and Brochothrix thermosphacta count compared to the control. The hydrogen sulfide formers count and Lactobacillus count were nil in the irradiated fish chunks. In terms of microbial and sensory qualities, it was found that electron beam irradiated samples had an extended shelf-life of 28-38 days (with respect to dose level), compared to the control which had a shelf-life of only 16 days.
