Reproductive Seasonality in the Fishes of a Tropical Stream

Ecology, 1978
The reproductive seasons of 6 species of characoid fishes inhabiting a tropical forest stream in Panama were determined from observations on gonadal condition and size frequency distribution of the populations over an 18—mo period. In this area the relatively mild dry season lasts °4 mo, stream discharge increases moderately during the rainy season ...

Journal of Archaeological Science, 1982
Abstract The method of seasonal dating from fish remain suggested by Leach is shown to be unsatisfactory. The method requires catch statistics that are at present unavailable.

Effect of Season and Environment on the Retinal Pigments of Two Fishes

Nature, 1964
DARTNALL et al.1 have shown that in the paired-pigment species Scardinius erythrophthalmus (visual pigments based on vitamin A1 and on vitamin A2) the retina is dominated by the vitamin A2-based pigment in the winter and by the vitamin A1-based pigment in the summer (in England at latitude 52° N.). The present report concerns a similar investigation on

Seasonality of reproduction by liverbearing fishes in tropical rainforest streams

Oecologia, 1993
Reproductive ecology, population structure, and diets of three common livebearing poeciliid fishes (Alfaro cultratus, Phallichthys amates, Poecilia gilli) from rainforest streams in Costa Rica were investigated over ten continuous months. The region experiences little annual temperature variation, and although monthly rainfall is continuous each year ...

Seasonal energy investment and metabolic patterns in a farmed fish

Journal of Thermal Biology
The present research focuses on the seasonal changes in the energy content and metabolic patterns of red porgy (Pagrus pagrus) sampled in a fish farm in North Evoikos Gulf (Greece). The study was designed in an effort to evaluate the influence of seasonality in several physiological feauteres of high commercial importance that may affect feed intake ...
