| Abstract: | A study was carried out in fall 1987 to determine if red drum (Sciaenops ocellatus) spawned in the southern portion of Mosquito Lagoon, Florida, 30 km from the nearest tidal pass. Weekly plankton tows were taken from mid-September to mid-November. Floating sciaenid eggs were removed from the samples and incubated 16–36 h: 329 red drun eggs were hatched. Viable red drum eggs were collected from October 27 to November 18 at salinities of 29‰ to 32‰ and water temperatures of 21°C to 23°C. The largest number of eggs was collected on November 4, during a full moon. This is the first documentation of red drum spawning in an estuary. The physiography and high salinity (which are more characteristic of marine than estuarine waters) of Mosquito Lagoon were probable factors in producing this phenomenon. |
