Seasonal Spawning Cycles of Two Marine Cottid Fishes, Chitonotus Pugetensis and Icelinus Quadriceriatus from Southern California
Abstract:Spawning cycles are described for two marine cottids from southern California. Histological analyses of seasonal collections indicated both species had prolonged spawning periods with maximum spawning activity from late winter to early spring. Spawning declined in summer, however, small numbers of females in spawning condition were collected in fall and early winter indicating the likelihood of some year-round spawning. It is postulated that both species produce at least three egg clutches per year. The winter peak spawning activity began earlier in 1978 than it did in 1977.
