| dc.description | From April 2010 to July 2012 data and samples on the biology and the fishery of Diapterus brevirostris (Teleostei: Gerreidae) were collected in the coasts of Colima and Jalisco. Total catches show fluctuations in the last twenty years in Colima. The catches in Jalisco do not show this species alone, but mixed with other “Mojarras” during the last eleven years. The highest catches in Colima and Jalisco are obtained during summer. First age and length of capture was at 2.04 years and 15.00 cm in Colima and 2.98 years and 19.80 cm in Jalisco. Total mortality was Z = 2.06 in Colima and Z = 1.96 in Jalisco. Natural mortality was M = 0.139 in both cases. Fishing mortality was F = 1.921 in Colima and F = 1.821 in Jalisco, with a survival rate of S = 0.127 in Colima and S = 0.141 in Jalisco. Exploitation rate was E = 0.933 in Colima and E = 0.929 in Jalisco. Yield per recruit was y/r = 106.47 g in Colima and y/r = 107.5 g in Jalisco. Increasing the age of first capture to four years old will get a y/r = 146.5 g for Colima and a y/r= 148.2 g for Jalisco. Keywords Capture, mortality, exploitation rate, yield per recruit, shortnose mojarra, Diapterus brevirostris. | |
