Reproduction Of Black Drum, Pogonias Cromis, From The Chesapeake Bay Region, Brian K. Wells, Cynthia M. Jones

Virginia Journal of Science

Ovaries of black drum, Pogonias cromis, collected from the Chesapeake Bay region in 1992, were used to describe reproductive strategy and fecundity. Histological examination showed that black drum spawn in the Chesapeake Bay region from April through early June. Distributions of oocyte diameter showed distinct oocyte-developmental groups indicating that Chesapeake Bay black drum are group-synchronous batch spawners. Female black drum are extremely fecund ranging from 414,000 to 3,736,000 hydrated oocytes (mean = 1,389,000) per batch with a spawning periodicity of 3.8 days. Estimates of spawning strategy, spawning periodicity, and batch fecundity for black drum from the Chesapeake Bay region …

Reproductive Differences Among Delmarva Grass Shrimp (Palaemonetes Pugio And P. Vulgaris) Populations, Holly H. Ganz, Robert E. Knowlton

Virginia Journal of Science

Populations of female grass shrimps (Palaemonetes pugio and P. vulgaris) were sampled from five coastal embayments in Delaware, Maryland, and Virginia (Delmarva) and compared with respect to reproductive and life history attributes. We observed interspecific differences in timing of reproduction, carapace length, ratio of carapace length to total body length, body weight, clutch weight, clutch size, and egg volume. Onset of reproduction in P. vulgaris lagged behind P. pugio. Although there was no difference in the relationship between clutch size and carapace length for the two species, carapace length/total body length in P. pugio was greater than …

Hydrobiid Snails (Mollusca: Gastropoda: Rissooidea) From St. Andrew Bay, Florida, Richard W. Heard, Robin M. Overstreet, John M. Foster

Gulf and Caribbean Research

Heleobops sp. of Hershler and Thompson appears to be the only previously published record for the gastropod family Hydrobiidae Troschel in tidal waters of the St. Andrew Bay System, Florida. Six species occurred in bayous, marshes, and brackish ponds associated with the System during studies conducted between 1984 and 1999: Texadina barretti (Morrison), Texadina sphinctostoma Abbott and Ladd, Littoridinops monroensis (Frauenfeld), Littoridinops palustris Thompson, Onobops jacksoni (Bartsch), and Heleobops sp. A. The last is an apparently undescribed species closely related to Heleobops carrikeri Davis and McKee. Based in part on this study, Heleobops sp. A, which occurs in brackish habitats …

Tanaidacea (Crustacea: Peracardia) Of The Gulf Of Mexico. X. The Question Of Being Male, Kim Larsen

Gulf and Caribbean Research

Three new species Parafilitanais mexicana, Collettea elongata, and Paragathotanais medius are described from deep-sea localities in the Gulf of Mexico. The male of Parafilitanais does not vary conspicuously from the female, except for possessing pleopods. Male Paragathotanais reveal that the mouthparts display some degree of sexual dimorphism. Males of all 3 species possess functional mouthparts. The problems identifying male Tanaidacea are discussed. The number of terminal spiniform setae on the maxillule is considered invalid as a diagnostic character. Keys to the species of Parafilitanais and Paragathotanais are given.

First Record And Habitat Notes For The Genus Lightiella (Crustacea, Cephalocarida, Hutchinsoniellidae) From The British Virgin Islands, Joel W. Martin, Donald B. Cadien, Todd L. Zimmerman

Gulf and Caribbean Research

The crustacean class Cephalocarida, as currently understood, is comprised of five genera and ten species (Hessler and Elofsson 1996, Hessler and Wakabara 2000). Although in some instances numerous specimens have been collected in a single locale (e.g., the nearly 120 specimens of Lightiella incisa Gooding, 1963 from Puerto Rico studied by Sanders and Hessler (1964), and the numerous specimens of Hutchinsoniella macracantha Sanders, 1955 now known from Buzzards Bay, Massachusetts, see Hessler and Sanders 1973:193), most reports are based on very few specimens. For example, the original description of the genus Hutchinsoniella Sanders, 1955 was based on only eight specimens …

Tanapseudes Gutui, A New Species Of Apseudomorphan Tanaidacea (Crustacea: Peracarida) From The Caribbean Sea And The Taxonomic Status Of The Family Tanapseudidae Băcescu, Thomas Hansknecht, Richard W. Heard, Roger Bamber

Gulf and Caribbean Research

Tanapseudes gutui, n. sp., is described from depths of 3–34 m off San Juan, Puerto Rico, and 4– 5 m off Goat Island, Tobago. Tanapseudes sinensis Bamber from Hong Kong waters is re-examined and determined to represent a junior synonym of the type species T. ormuzana Băcescu which was originally collected in the Straights of Hormuz off Iran. Tanapseudes gutui can be distinguished from T. ormuzana by several characters including details of the mouth parts, the presence of a reduced spiniform seta on the distotergal margin of the propodus of pereopod 1, pereonites 3–6 with rounded anterior margins, and …

Spatial And Temporal Variability In Zooplankton Community Dynamics In Three Urbanized Bayous Of The Pensacola Bay System, Florida, Usa, Emile M. Lores, Michael A. Lewis, Ziad A. Malaeb

Gulf and Caribbean Research

Spatial and temporal patterns in zooplankton community composition and abundance in coastal areas of the Gulf of Mexico are not well understood. Spatial and temporal differences in zooplankton community composition and abundance from 10 stations located in four sites are presented (Pensacola Bay and Bayou Texar, Bayou Chico, and Bayou Grande, three adjacent mesohaline-tidal bayous affected by urban and industrial development). Statistically significant differences (P < 0.05) were found in log-biovolume among sites. The mean biovolume of zooplankton was highest in Pensacola Bay (0.38 ml m^-3) followed by Bayou Grande (0.21 ml m^-3), Bayou Chico (0.14 ml m^-3), and Bayou Texar (0.06 ml m^-3). Mean zooplankton abundances (organisms m^-3) in Pensacola …

Crustacea Of The Cayman Islands, British West Indies. I. Records Of Mysids From Shallow Water Non-Reef Habitats, W. Wayne Price, Richard W. Heard, Jason T. Harris, Croy M.R. Mccoy

Gulf and Caribbean Research

A single species of mysid Siriella chierchiae has been previously reported from the Cayman Islands. However, between May 1995 and August 1999, 20 species of mysids were collected from shallow water non-reef habitats surrounding Grand Cayman and Little Cayman Islands. Of the species collected, one species Anchialina typica has a cosmopolitan distribution in tropical and subtropical seas. Thirteen species (Amathimysis cherados, A. gibba, Bowmaniella johnsoni, Dioptromysis paucispinosa, Heteromysis bermudensis, H. mayana, Mysidium columbiae, M. gracile, M. integrum, Mysidopsis bispinulata, M. brattstromi, Parvimysis bahamensis, Siriella chierchiae) are …
