|Title:||Catch rates and sustainable yield of Hook and Line Fishery - A Case Study of Kombuthurai village of Thoothukudi district of Tamilnadu|
|Keywords:||Hook and Line;Maximum sustainable yield;Surplus production models|
|Abstract:||To estimate the maximum sustainable yield (MSY) and optimum effort (FMSY) values during 2009-2013, the surplus production models (Schaefer and fox) were used. For the Schaefer model, they were 434 tons (R2 = 0.99) and 1252 hours respectively, while from the Fox model the values were 625 tons (R2 = 0.99) and 1000 hours respectively. For the period 2009-2013 the estimated monthly MSY and FMSY values for the Schafer model were 36.95 tons (R2 =0.88) and 185 hours respectively, while from the Fox model it was 31.8 tons (R2= 0.99) and 200 hours respectively. The sustainable catch during the study period (2009-2013) on a yearly basis was confirmed from MSY level, and hence, the overall catch can be considered as sustainable.|
