Alive digeneans were collected from the digestive tract of Sparus aurata (Teleostei, Sparidae), caught from the Gulf of Gabès in Chebba, Tunisia (Eastern Mediterranean Sea). The male gamete of M. obovata is a filiform cell, tapered at both extremities and exhibits typical characters such as two axonemes of different lengths showing the 9+‘1’ trepaxonematan pattern, a nucleus, mitochondria, two bundles of parallel cortical microtubules, external ornamentation of the plasma membrane, spine-like bodies and granules of glycogen. -

Scientific Studies on Dry Tortugas National Park: an Annotated Bibliography
ATOLL RESEARCH BULLETIN NO. 449 SCIENTIFIC STUDIES ON DRY TORTUGAS NATIONAL PARK: AN ANNOTATED BIBLIOGRAPHY BY T.W. SCHMIDT AND L. PIKULA ISSUED BY NATIONAI, MUSEUM OF NATURAL HISTORY SMITHSONIAN INSTITUTION WASHINGTON, D.C., U.S.A. OCTOBER 1997 SCIENTIFIC STUDIES ON DRY TORTUGAS NATIONAL PARK: AN ANNOTATED BIBLIOGRAPHY Thomas W. schmidt1 and Linda pikula2 ABSTRACT Dry Tortugas National Park, located 110 km west of Key West, Florida, is an elliptical, atoll-like, coral reef formation, approximately 27 km long and 12 km wide with shallow water depths ranging from 12-20 m in channels between reefs. In 1935, the area was designated Fort Jefferson National Monument, the World's first underwater National Park unit. Central to the area is Fort Jefferson, America's largest coastal nineteenth century masonty fort. In 1992 it was re-designated Dly Tortugas National Park. Because of the islands' unique location, the first tropical marine biological laboratory in the Western Hemisphere was established on Loggerhead Key by the Carnegie Institution of Washington, Washington, D. C. Following the closure of the Tortugas Laboratory in 1939, aperiodic marine biological assessments have been conducted in response to man- made and natural environmental perturbations. This annotated bibliography is an attempt to provide researchers and resource managers with access to the rapidly accumulating body of information on the park's natural resources. A total of 424 references (published and unpublished) on scientific studies in, (and what later became) Dry Tortugas National Park were annotated and indexed according to major scientific topics. Studies from a wider area were included if they also sampled in Dry Tortugas National Park. -

Larry G. Allen, Ph.D., Principal Investigator Director, Southern California Marine Institute and Professor of Biology California State University, Northridge 9 EXECUTIVE SUMMARY • We tested the feasibility of using an innovative approach that will prove to be an extremely valuable technique for all future stock assessments of coastal pelagic species off southern California. We conducted a hydroacoustic (sonar) assessment of barred sand bass standing stock (abundance and biomass) using high resolution split beam sonar verified by both rod and reel sampling over sonar targets and underwater video observations. Simply put, we plan to visually identify conspicuous acoustic targets, identify these targets with both rod and reel sampling and underwater video towed by the research vessel. Once a target is verified (e.g., as an aggregation of barred sand bass), its target strength can be related quantitatively to abundance and biomass. • The feasibility phase of this study was conducted over five days in July (peak spawning months for barred sand bass) of 2010 over the 20-30m depth contour at Huntington Flats. Each day the sampling, area was easily determined by the positioning of the sport fishing fleet including Commercial Passenger Sportfishing Vessels (CPFVs) and private vessels targeting sand bass from San Pedro, Long Beach and Newport Beach. -

(Accepted 14 February 2005) Abstract For 40 years there have been problems in diagnosing sexual patterns in the serranid genus Paralabrax. Difficulties stem from a combination of factors including terminology, histological and morphological characteristics, and the complex inter-relationships in the Serranidae between gonad morphology, phylogenetic position and gonad function. A detailed study of four species of Paralabrax: P. maculatofasciatus, P. nebulifer, P. auroguttatus and P.clathratus, clarifies the problems and improves the diagnosis of sexual pattern in the Serranidae, and for similar families that do not have distinct morphologies for primary- and secondarily-derived males. An hypothesis was developed to account for the multiple appearance of gonochorism in the Serranidae, better known for its widespread hermaphroditism. Key words: Serranidae, sexual pattern, hermaphroditism, Paralabrax INTRODUCTION inversion (secondary male) or has been born as a male (primary male)’ (our italics).

Evaluation of Eelgrass Mitigation and Fishery Enhancement Structures in San Diego Bay, California
BULLETIN OF MARINE SCIENCE, 78(1): 115–131, 2006 EValuation of EelGrass MitiGation anD FisHerY ENHancement Structures in San DieGO BAY, California Daniel J. Pondella, II, Larry G. Allen, Matthew T. Craig, and Brooke Gintert ABSTRACT To offset habitat loss and increase fishery production, an eelgrass mitigation habi- tat was completed in San Diego Bay, California in 1997. This mitigation effort con- sisted of the transplantation of eelgrass, Zostera marina L., in the western portion of the bay. In addition to the establishment of a new eelgrass bed, four enhancement reefs made of either quarry rock or concrete rubble were created to further enhance fishery stocks and the area’s ecosystem. Two design criteria and a direct comparison between quarry rock and concrete reefs were examined in this 5-yr pilot program. The newly created eelgrass habitat quickly performed at the level of the existing eelgrass bed. The overall analysis found that the mitigation eelgrass habitat was not significantly different from the reference eelgrass habitat in terms of fishes. Neither reef material (quarry rock or concrete rubble) nor original reef design influenced fish utilization. In addition, aspects of fishery enhancement were examined on the enhancement reefs using three target species of Paralabrax (Perciformes: Serra- nidae). Resource utilization differed among these congeners with differing levels of production. Using enhancement reefs and eelgrass transplantation, enhancement and mitigation goals were achieved in San Diego Bay. Mitigation and enhancement to restore and offset habitat loss in estuaries contin- ues at an increasing pace throughout the world. This is necessary due to the world- wide degradation and loss of these habitats and, in particular, the characteristic seagrasses found in estuaries (Short and Wyllie-Echeverria, 1996). -

During a year and thereby all four seasons, 20 wild and 20 cultured groupers were examined for the pres- ence of parasites, except in the last season, in which 19 wild and 20 cultured fish were examined, totalling 159 groupers analysed from Ubatuba, southeastern Brazil. Prevalence, mean intensity of infection, mean abundance and mean rela- tive dominance were calculated. Five species of parasites were identified in fish from both origins: Pseudorhabdosynochus beverleyburtonae (Monogenea), Neobenedenia melleni (Monogenea), Pseudempleurosoma sp. (Monogenea), Helicometrina nimia (Digenea) and larvae of Contracaecum sp. (Nematoda). The prevalence of ectoparasites, in most cases, was higher than endoparasites. The most abundant parasite was the monogenea Pseudorhabdosynochus beverleyburtonae in both wild and cultured fish, along all seasons.
