Most of the marine wild life becoming extinct or endangered due to natural and manmade activities. To contain the biodiversity the attempts has been made to conserve, preserve and protect the marine biodiversity. Number of acts including Indian Fisheries act were implemented since 19th century. In this paper review has been taken for endangered marine organism as on date and the acts and laws to conserve, protect and preserve biodiversity by the government point of view.

The Catch Per Unit Effort (CPUE) of all kinds of marine fishing fleet is depleting day-by-day as the number of fishing vessels of all categories has increased remarkably, making the fishing business uneconomical. The time spent by vessel on seeking the resources is more thus results into additional spending on fuel cost. Considering the problem of the fishers the present study was undertaken to validate Potential Fishing Zone (PFZ) forecast is generated and disseminated by Indian National Center for Ocean Information Services (INCOIS) for both west and east coast of India. Mirkarwada being one of the important fishing harbours landing majority of purse-seine catches in this area was selected as base-port in the study area. Coastal area between 18° 00́ N 72° 00́ E to 15° 43́ N 73° 33́ E with 288 km coastline was selected for the present study. Each potential fishing zone forecasts during the study period was disseminated to 15 purse-seiners, which were selected as sampling units and the feedback was collected from them regarding location of fishing, catch composition and duration of fishing. The analysis of data revealed that catches recorded in notified PFZs were significantly higher than non-PFZs with 43.90% enhancement in catches throughout the season (P < 0.05) except in the month of March. The relationship established between total catch on number of hauls of purse-seines fished in PFZ (Y-1353.9X) was better than the relation established for purse-seines fished in non-PFZ (Y=866.41X) whereas, fishing success rate in PFZ was 72.79% during the fishing season. The present study concluded that the vessels fishing in notified PFZ were benefited with increased Catch Per Unit Efforts and reduction in fuel expenditure and fishing hours over the vessels fished in Non-PFZs.

The study on the age, growth and mortality of white fish, Lactarius lactarius was carried out based on the length frequency data collected during August 2009 to August 2011. The asymptotic length ((L∞)) and growth coefficient (K) were estimated as 366 mm and 0.685 yr-1 respectively. The total, natural and fishing mortalities were 3.31, 1.30 and 2.01 yr-1 respectively. The exploitation rate (U) and exploitation ratio (E) were calculated as 0.61 and 0.62 respectively. Though Emax obtained at 0.91, it is not advisable for a stock to be exploited at that level as in future, it would be detrimental. © 2015, National Institute of Science Communication and Information Resources (NISCAIR).

Indigenous knowledge can be judiciously blended with modern scientific knowledge and its benefit to the fishers can be greatly improved. Bivalve fishery is traditionally practiced along the estuarine ecosystems in coastal district of Ratnagiri in Maharashtra. Fishermen, by virtue of their intricate association with coastal environment and daily observations of natural resources possess rich indigenous knowledge (IK). In present study, an attempt was made to validate the indigenous knowledge of fishermen related to the seasonal edibility of Baby clam (Katylesia opima) with respect to season-wise variation in the quantity of meat. Data on edibility of clams was collected from 50 fishermen using semi-structured schedules. For validation of the indigenous knowledge, laboratory data on percentage edibility, lipid, protein, ash and glycogen were collected and analyzed. In clams, all the variables tested only the lipid content and percentage edibility (PE) returned significant results (p < 0.05). The summer season displayed the median value, while monsoon the highest and winter the lowest for both the variables. Further, PE and lipid varied significantly during monsoon and winter season (p<0.05). An important aspect of IK that lowest edibility is associated with winter is validated by the study. © 2015, National Institute of Science Communication and Information Resources (NISCAIR).

Fishermen rely on their knowledge for their livelihood, so it has always been 'put to work' in the most practical sense. Study of the indigenous knowledge held by the fishermen will help in its recognition and preservation, besides generating important information base and pinpointing essential future research needs. The present study was conducted to gain access to the indigenous knowledge of the fishermen engaged in the bivalve fishery practiced in the region. A total of 100 fishermen constituted the sample size of the study. The data were gathered through a combination of personnel interview and non-participant observation methods. The study has documented rich, varied and potential indigenous knowledge associated with the management of the bivalve fishery. Indigenous knowledge on variety specific habitats, fishery season for bivalves, methods of their exploitation and preservation has been documented. Similarly indigenous knowledge related to preference timing and depth for bivalve exploitation, preparation of byproducts, and effect of different abiotic phenomenon on condition and availability of bivalves is noted.
