Feasibility of targeted fishing in mesoscale oceanic eddies: a study from commercial fishing grounds of Andaman and Nicobar Islands, India Anand Arur, Pandian Krishnan, R. Kiruba-Sankar, Arun Suryavanshi, K. Lohith Kumar, Ganesan Kantharajan, S.B. Choudhury, C. Manjulatha, D.E. Babu International Journal of Remote Sensing, 2020 Mesoscale eddies are important ocean phenomena that enhance biological productivity by mixing of water column and influence fishery catches, especially in stratified seas such as Bay of Bengal and Andaman Sea. The current study was conducted around the Andaman and Nicobar Islands (ANI), India located in the Eastern Indian Ocean. The study tested the feasibility of targeted fishing in eddies, by characterizing the mesoscale eddies in the region, towards developing operational altimetry-based fishery advisories for the fishers. We analysed fish catch data from 15,370 commercial fishing trips from the Islands using five fishing gears during 2014–17 spatially vis-à-vis the eddies delineated from Maps of Sea Level Anomaly (M-SLA). We show that 5-24% of the routine commercial catches occurred in eddies, fishery catches are positively influenced by different eddy zones and the fish catch using different fishing gear are significantly higher in some of the eddy zones. We generated experimental advisories showing locations of eddies and their zones, identified using Near Real-Time M-SLA data and guided the commercial fishers for targeted fishing in eddies. The fish Catch Per Unit Effort (CPUE) from the experimental fishing within the eddy zones was significantly (p < 0.01) higher than that from the traditional fishing grounds in the non-eddy areas. The spatio-temporal analysis of eddies around ANI during 2009–16 showed the occurrence of higher number of anticyclonic eddies, majority of which move westward and have a lifespan of less than 2 weeks and amplitude less than 4 cm. In the current study, the areas around ANI with frequent eddy occurrence and eddy density have been identified, which could aid in increasing the fishing intensity by targeting the pelagic fishes, using longlines, gillnets and ringnets. Thus, we show the possibility of using eddy fishing advisories generated from altimeter data, for augmenting the currently operational Potential Fishing Zone (PFZ) advisories that are generated using optical/thermal remote sensing data and disseminated to the coastal fishers in India. This will be helpful especially for the regions with and during periods of persistent cloud cover.

A histological study of polypoidal stomach in Nemipterus japonicus offVisakhapatnam coast Thelagathoti Conrad Diana, Chapara Manjulatha Indian Journal of Science and Technology, 2016 Background/Objectives: Histopathological screening of a typical polypoidal stomach and associated organs was performed on Nemipterus japonicus off Visakhapatnam coast. Methods: 1832 specimens were collected from Visakhapatnam coast at a depth of 45m-100m within the period January 2011 to December 2013 were examined for documenting lesions in the stomach. Of the total samples about 18% of fish were identified with typical mucosal polyps which were autopsied and tissues of skin, gill, muscle, stomach, intestine, liver, spleen, kidney and gonads of both normal and diseased fish were fixed in 10% buffered formalin for 48 hours and dehydrated in graded alcohols, followed by impregnation in paraffin. The embedded blocks are cut 5 μ thick on a microtome and sections stained with haemotoxylin and eosin, for the examination of pathological changes in the tissues. Findings: These studies revealed macroscopic lesions with a polyp arising from the mucosa of the gastric body leading to herniation of other digestive glands such as liver and pyloric caecum into the lumen of the polypoidal stomach. Histologically, the growth was differentiated as adenomatous polyp with abnormal proliferation of gastric mucosal glands in the stomach with focal erosion and hemorrhage. This evidence suggested chronic gastritis, but the cause of these unusual gastric polyps is unclear. Though earlier microbiological studies revealed the presence of enteric bacteria, with a dominance of Klebsiella pneumoniae, virological investigations failed to confirm any oncoviral particles and even aflatoxin analysis gave negative results. Immunological and karyological studies of N. japonicus with mucosal buccal polyps showed mitodepression. Application/Improvements: This is first histopathological report of this kind in N. japonicus and may help as a model for future studies on gastric polyposis in both human and animals.
