The Influence Of Habitat And Fishing On Reef Fish Assemblages In Cuba, Gaspar Gonzalez-Sanson, Consuelo Aguilar, Ivet Hernandez, Yureidy Cabrera, R. Allen Curry
Gulf and Caribbean Research
The abundance of selected fish species was estimated using the stationary visual census technique in the northwestern region of the Cuban shelf. A total of 26,809 individuals of 32 species were counted in 1,172 stationary point censuses made at 10 reef sites along the coast. We found that the abundance patterns were most probably the consequence of the presence/absence of mangroves and seagrass beds in adjacent lagoon areas. A second factor influencing the spatial variation appeared to be overfishing on an east-west gradient, with lower abundances of commercially targeted species near Havana City in the east.

Morphological Characteristics Of The Carapace Of The Hawksbill Turtle, Eretmochelys Imbricata, From Cuban Waters, Mari Kobayashi
Gulf and Caribbean Research
Hawksbill turtles, Eretmochelys imbricata (Linnaeus, 1766), from Cuban waters of the Caribbean were analyzed to determine the relationships between straight carapace length (SCL) and either straight carapace width (SCW) or body weight (Wt). The regression equations were SCW = 0.9136(SCL)0.951 (R2 = 0.923, n = 315) and Wt = 4.17 x 10–4(SCL)2.68 (R2 = 0.798, n = 289), respectively. The regression equations between the first costal width (C1W) and either SCW or Wt were SCW = 3.223(C1W)0.847 (R2 = 0.919, n = 156) and Wt = 1.416 x 10–2(C1W)2.426 …

Spawning Aggregation Sites Of Snapper And Grouper Species (Lutjanidae And Serranidae) On The Insular Shelf Of Cuba, Rodolfo Claro, Kenyon C. Lindeman
Gulf and Caribbean Research
Twenty-one spawning aggregation sites on the Cuban shelf were identified for eight species of snappers (Lutjanus) and groupers (Epinephelus and Mycteroperca) using information from experienced fishers and field studies. Three sites are on the southeastern shelf, eight on the southwest shelf bordering the Golfo de Batabanó, two in the northwest, and eight in the north-central region along the margins of the Archipiélago de Sabana-Camagüey. These numbers may reflect sampling effort as much as absolute aggregation numbers, with most effort concentrated in the southwest and north-central regions. Additional studies, particularly field assessments, are needed to determine the …
