Gulf and Caribbean Research
Of all the coastal shark species in the northern Gulf of Mexico, the nurse shark, Ginglymostoma cirratum, is one of the few species not documented in the Sound. Unlike most coastal sharks, nurse shark distribution is confined to a relatively specific suite of abiotic characteristics. Hannan et al. (2012) demonstrated that the distribution of nurse sharks in the northern GOM is primarily limited to hard bottom habitats with relatively high temperature, salinity, dissolved oxygen, and water clarity. Herein, we provide support for the findings of Hannan et al. (2012) and report the first documented occurrence of a nurse shark …

Estimates Of Harvest Potential And Distribution Of The Deep Sea Red Crab, Chaceon Quinquedens, In The North Central Gulf Of Mexico, Richard Waller, Harriet Perry, Christine Trigg, James Mcbee, Robert Erdman, Norman Blake
Gulf and Caribbean Research
Harvest potential, relative abundance, and geographic and bathymetric distribution are discussed for the red crab, Chaceon quinquedens, in the northcentral Gulf of Mexico. Harvest potential is expressed as the number of trapable crabs present on fishing grounds defined as depths ranging from 677 m to 1043 m between 87.5o and 88.5oW longitude. Using various estimates of the effective fishing area (EFA) of a trap, the number of trapable red crabs on the fishing grounds ranged from 3.7 x 106 to 10.7 x 106. Estimatesofcrabnumberssuggest there is a potential for commercial harvest in the …
Taxonomy And Distribution Of Edotea (= Tropedotea) Lyonsi (Menzies And Kruczynski, 1983) N. Comb. (Crustacea: Isopoda: Idoteidae), Gary D. Goeke, Richard W. Heard Jr.

Tropedotea lyonsi Menzies and Kruczynski, 1983, is reported from the waters off Alabama southeastward to Cape Romano, Florida. The monotypic genus Tropedotea was recently erected on the basis of coxal plates of pereonites V to VI1 visible in dorsal view and a reduced number of articles in both antennae. Pereonites V to VI11 are also visible in dorsal view in Edotea Guérin-Ménéville, 1843, and the number of articles in antenna 1 and 2 of Tropedotea Menzies and Kruczynski, 1983, is the same as in Edotea. Hence Tropedotea lyonsi is assigned to the genus Edotea and Tropedotea is designated a …
