- Abstract
This work determined the reproductive strategies of seven marine fish species from the coastal region of Rio Grande do Norte, Brazil. Life history traits of fish in relatively stable environments suggest a model of three reproductive strategies: (1) opportunistic strategists, fish with small body size, early first sexual maturity, short-life span and low fecundity; (2) seasonal strategists, fish with body size and first sexual maturity both intermediary, with intermediate to high fecundity; and (3) equilibrium strategists, fish of big body size, long life span, late first sexual maturity, with high fecundity. Aspects of reproductive strategies of Hirundichythys affinis, Hemiramphus brasiliensis, Pomadasys corvinaeformis, Oligoplites palometa, Scomberomorus brasiliensis, Lutjanus synagris and Mugil curema were verified according to the body size, sex ratio, length at first sexual maturity, aspects of gonad development, fecundity, type of spawning and reproductive period of the fish. The results suggest that H. affinis, H. brasiliensis, P. corvinaeformis and O. palometa could be considered as opportunistic strategists. On the other hand S. brasiliensis, Lutjanus synagris and M. curema could be considered as equilibrium strategists. This study provides information on the reproductive aspects of fish which constitute the fishery stocks of the coastal waters of Rio Grande do Norte, Brazil.
