| Abstract: | Based on the test fishing in the Southeast Pacific Ocean,the basic biological characteristics of catch composition,the relationships of length weight and age growth,and mature stage etc.of horse mackerel ( Trachurus murphyi ) were investigated.The results indicated that the fork length and body weight of horse mackerel ( T. murphyi ) varied between 145~610 mm in length?42~1 950 g in weight respectively,and the age varied from 2 to 13 years old, consisting mainly of 3 and 4 years old individuals.The maturity rhythm of individuals at different ages varied markedly with the first mature age of 3. |
