ESPINO-BARR, Elaine; GALLARDO-CABELLO, Manuel; GONZALEZ-OROZCO, Fernando  and  GARCIA-BOA, Arturo. Growth and mortality of Anisotremus interruptus (Gill) (Perciformes: Haemulidae) on the coast of Colima, México.. Bol. Invest. Mar. Cost. [online]. 2004, vol.33, n.1, pp.69-77. ISSN 0122-9761.

This paper deals with the growth and mortality analysis of the burrito grunt Anisotremus interruptus on the coast of Colima, México. The estimated growth parameters are: L∞ = 50.59 cm; W∞ = 5,051.04 g; k = 0.147 years^-1; t_o = -0.916 years; A_0.95 = 19.46 years. Most of the growth occurred during the first year of life, when the grunt grows 12.52 cm, the second year it grows 4.95 cm and the third, 4.60 cm. The highest value of the condition index took place between February and September. The total mortality rate (Z) was calculated as 0.53 years^-1. These values are basic for the plan of administration of the fishery of this species.

Keywords : Anisotremus interruptus; Haemulidae; Growth; Mortality.
