- Abstract
The article presents information on cyprinodon laciniatus, a rare fish. The bodies of water that this species inhabits are brackish with salinities ranging from 10-14 ppt. The bottom is marl over limestone in the form of coarse cobble and boulders. Algae, chiefly Batophora are abundant. Transect studies reveal the greatest abundance of individuals to be within 10 m of the shore at depths ranging from 0.3 to 1.2 m. Although feeding studies have not been done, the Bahama pupfish is probably similar to the sheepshead minnow in consuming mainly plant matter and detritus. The differences in dentition between the two species suggest some feeding specializations, however. Reproduction: Although studies on the reproductive biology of C. lacinicitus have not been done, fecundity measurements of several populations of Gyp rinodon from New Providence have been performed. Total number of eggs produced closely correlates with size of the individual and ranges from 20 to 250 eggs per ovary. The presence of eggs at different stages of maturation indicates that spawning takes place throughout the year.
