This species is important in terms of recreational and consumptivefishing, and conservation. Although bigmouth sleeperstypically inhabit lotic habitats, they have been found in four reservoirs in PuertoRico. In Carite Reservoir, abundance and size data indicate that habitat is suitablehabitat for bigmouth sleepers, and the presence of a diversity of size classes ofsleepers suggests that either in-reservoir reproduction or significant recruitmentto the reservoir from an outside source is occurring.

This research was initiated to evaluate the likelihood of each, and to learn more broadly about bigmouth sleeperecology. Population biology, diet, and reproduction of bigmouth sleepers in CariteReservoir were examined between and Many sizes of bigmouth sleepers werecollected during this study, ranging from 25 to mm TL.

The estimated totalpopulation size in and was 1, and 3, fish, respectively. Daily growthrate of tagged fish ranged from Diet of small bigmouth sleepers 50 - mm TL mainlyconsisted of insects, whereas larger fish primarily preyed upon fish and freshwatercrabs.

Sexual dimorphism of bigmouth sleepers was evident in the anatomy of theirurogenital papillae; these differences developed at sizes as small as 50 mm TL and persisted throughout the year. Reproduction was seasonal, with the highest gonadosomaticindicies occurring in May and June and the lowest in January and February. The smallestmature male observed was mm TL, while the smallest mature female was mm TL.

The largest oocytes observed were 0. Fecundity was negatively correlated with date, suggesting batch spawning.
