Births and growth models of sea lions and their application in the management of this resource

Based on studies of the sea lion carried out on the island of Angel de la Guarda in the Gulf of California during 1986, 1987 and 1988, it has been established that the reproductive season of sea lions is between May and June. The births begin in the third week of May and end in the third week of Jul...

The births begin in the third week of May and end in the third week of July. It has been recommended that special captures of live animals should only be allowed between the months of January and March. This study proposes that the weight and size increment of the pups during their first year of life responds, in the case of males to a potential model, and in females to an exponential model. From these models we can derive the minimum capture size of 100 cm length and 19 kg weight. This size is reached by the age of seven months. A partir de estudios realizados con el lobo marino en la isla Angel de la Guarda, Golfo de California, durante los años de 1986, 1987 y 1988, se establece que su periodo de reproducción se presenta de mayo a julio; los nacimientos se inician en la tercera semana de mayo y terminan en la tercera semana de julio. Se recomienda que las capturas especiales de animales vivos se realicen solamente de enero a marzo. Se propone que el incremento en peso y longitud de las crías durante su primer año de vida responde, en el caso de las crías machos, a un modelo potencial y en el caso de las crías hembras, a un modelo exponencial, de los cuales se deriva que las tallas mínimas de captura sean de 100 cm de longitud y 19 kg de peso; dichas medidas se alcanzan a los siete meses de edad.
