Abstract

Ever since marine fishery operations were extended beyond territorial  waters of respective states, the need was felt for incorporating spatial  component of fishing effort and catch for formulating marine fishery policies. The present study is an attempt of spatio-temporal analysis of changing  scenario of fishing operations in GIS platform with catch and effort data collected from fishermen, to highlight the need for the change in approach in fisheries management and also for updating the information of fishing along the Indian coast. Marine fishing operations by commercial fishing vessels operated from different states has extended up to 200 m depth since 2000 and duration of fishing, especially trawling extended from single day to 8-13 days per voyage. Present findings were drawn from the analysis of 1,217 days of trawling operations during 2007-2013 by a sampling trawler supplemented by additional fishing operational data support from a group of commercial trawlers. Study reveals that there is an organised and confidential maintenance of log sheets in most of the progressive trawler operators and the information available in spatial platform can be utilized for better fisheries management with fishermen’s participation. Spatial analysis of fish catch from the sampling trawler operated from Mangalore showed that more than 70% of the fish landed in Mangalore was brought from the area beyond the territorial waters of Karnataka signifying that majority of fish catch landing to the state is from waters beyond their jurisdiction. Even though the fishery beyond territorial waters of all maritime states is s governed by Government of India, so far, there is no comprehensive management plans regarding fishing operations beyond territorial waters of the states. The study further reveals that fishing grounds beyond territorial waters of each state are being intensively fished without any fishing regulations and there were many conflicts being reported from these waters concerning the fishing rights of different sectors and different states. In the light of the findings from the study on fishing operations and fishery, an action plan to regulate the fishery off the territorial waters of each state is felt essential. “Regional fisheries committees” with members constituting the officials from neighbouring states sharing same resources with the aegis of Central Government is recommended as a viable option to take care of the
management of the fishery within the Indian EEZ.
