OES Theses and Dissertations
Mandibular organs of the mud crab, Rhithropanopeus harrisii (Gould) were histologically located and followed throughout the larval cycle to determine their role in metamorphosis. Specimens from each day of the four larval stages and the megalopa stage were embedded in paraffin, sectioned at 8 μm, stained and observed under the microscope for the mandibular organs. The organs were located in the mandibular area of second, third and fourth stage larvae. The organs were probably present in the first stage zoeae and in the megalopa stage, although the
techniques of the study were not sensitive enough to observe them. The …

The Influence Of Lobster Trap Escape Gaps On Capture And Behavior Of The Spiny Lobster, Panulirus Argus (Latreille), Denis William Frazel
HCNSO Student Theses and Dissertations
Interest in the potential usefulness of lobster trap escape gaps in the Florida spiny lobster fishery prompted an independent examination of their influence on capture and behavior of the spiny lobster, Panulirus argus. A trapping study was conducted off Southeastern Florida during 1984/1985 using control traps, and traps with escape gap openings of 51, 54, and 57 mm. The 51 mm escape gap caught significantly more legal lobsters than any other trap, while the 54 and 57 mm escape gap caught significantly fewer sublegal lobsters. Carapace lengths of lobsters increased as escape gap width increased.
