The Marine Life Fishery in Florida, 1990–98

The marine life fishery in Florida is defined as the harvest of live marine specimens (fish and invertebrate species including plants, and also live rock, and live sand) for commercial use, primarily as ornamentals for the aquarium market. This paper summarizes the regulatory measures that have been implemented and the data collected on 318 species between 1990 and 1998. Regional analysis shows the primary collecting areas, and seasonal analysis shows when the majority of landings occur. Statistics on the number of participants provide insight into the size of the industry.

Spatial and Temporal Distribution of Sea Turtles in the Western North Atlantic and the U.S. Gulf of Mexico from Marine Recreational Fishery Statistics Survey (MRFSS)

Systematic surveys, along with opportunistic sightings, have provided important information on sea turtle (Cheloniidae and Dermochelydae) distributions, knowledge which can help reduce the risk of harmful human interaction. In 1991 and 1992, the Marine Recreational Fishery Sta- tistics Survey (MRFSS) of the National Ma- rine Fisheries Service, NOAA, provided a unique opportunity to gain additional, synoptic information on the spatial and temporal distribution of sea turtles along the U.S. Atlantic and Gulf of Mexico coasts by asking recreational anglers if they had observed a sea turtle on their fishing trip. During the spring and summer months of those years, as water temperatures warmed, the MRFSS documented an increase in sea turtle sightings in inshore waters and in a northward direction along the U.S. Atlantic Coast and in a westward direction along the northern Gulf of Mexico. This pattern reversed in the late summer and fall months as water temperatures cooled, with sea turtles concentrating along Georgia and both coasts of Florida. Although the MRFSS did not provide species or size composition of sea turtles sighted, and effort varied depending upon location of fishing activity and time of year anglers were queried, it did provide an additional and useful means of ascertaining spatial and temporal distributions of sea turtles along these coasts.

William Francis Thompson (1888–1965) and the Dawn of Marine Fisheries Research in Californ

William Francis Thompson (1888–1965), an early fishery biologist, joined the California Fish and Game Commission in 1917 with a mandate to investigate the marine fisheries of the state. He initiated studies on the albacore tuna, Thunnus alalunga, and the Pacific sardine, Sardinops sagax, as well as studies on other economically important marine organisms. Thompson built up a staff of fishery scientists, many of whom later attained considerable renown in their field, and he helped develop, and then direct, the commission’s first marine fisheries laboratory. During his tenure in California, he developed a personal philosophy of research that he outlined in several publications. Thompson based his approach on the yield-based analysis of the fisheries as opposed to large-scale environmental studies. He left the state agency in 1925 to direct the newly formed International Fisheries Commission (now the International Pacific Halibut Commission). William Thompson became a major figure in fisheries research in the United States, and particularly in the Pacific Northwest and Alaska, during the first half of the 20th cent

A Preliminary Study of the Marine Biota at Navassa Island, Caribbean Sea

A preliminary study of reef fish and sharks was conducted at Navassa Island in the Caribbean Sea during a 24-h period beginning 9 September 1998. Conducting a study at Navassa Island was of particular interest because exploitation of Navassa Island’s fishery resources has been considered minimal due to its remote location (southwest of the Windward Passage, Caribbean Sea) and lack of human habitation. Reef fish (and associated habitats) were assessed with stationary underwater video cameras at 3 survey sites; sharks were assessed by bottom longlining at 5 survey sites. Fifty-seven reef fish identifications to lowest possible taxon were made from video footage. Longline catches produced 3 shark species and 3 incidental catch species. When results from the 1998 National Marine Fisheries Service (NMFS) project are combined with a previous 1977 NMFS survey of Navassa Island, 27 fish families, 79 fish identifications to lowest possible taxon, 4 invertebrate orders or families, 3 coraline families, and 2 macroalgae phyla are reported.

Caracterização ambiental preliminar de um sistema rio estuário tropical em área de Mata Atlântica, Ilha Grande (RJ).

O presente trabalho visa contribuir para a valorização e conservação dos cursos dágua e biodiversidade em área de Mata Atlântica no Estado do Rio de Janeiro, através da caracterização ambiental preliminar do sistema rio - estuário Córrego Andorinhas, localizado no Parque Estadual da Ilha Grande (RJ), utilizando indicadores abióticos e bióticos. As amostragens ocorreram de 20/10/11 a 22/10/11, pela manhã e tarde, em duas profundidades de três estações. O fitoplâncton e protozooplâncton foram coletados com frascos de polipropileno (500 ml), fixados com formaldeído 2% neutralizado com bórax e analisados em câmaras de sedimentação de Uthermöl. O zooplâncton foi coletado com rede de 68 μm de malha, fixado com formaldeído 4% neutralizado com bórax e analisado em subamostras. Variáveis abióticas foram analisadas in situ com sondas. Os nutrientes foram coletados com garrafa de Van Dorn e frascos de polipropileno, congeladas e levadas para análise no laboratório de Geoquímica da UFF. A estação AN-01 apresentou menores valores de temperatura da água (19 C), condutividade (2,3 μS/cm) e turbidez (1,1 UNT), mas com maiores valores de OD (9,6 mg/L). Maiores valores de turbidez (6,9 UNT) e pH (7,7) foram registrados na estação AN-02, enquanto a estação AN-03 apresentou maiores valores de temperatura da água (23,7 C) e condutividade (1951 μS/cm). O fitoplâncton apresentou valores máximos nas estações AN-02 manhã em 22/10/11 (4,28 x 103 ind/L) e AN-03 tarde em 20/10/11(3,4 x 103 ind/L). O zooplâncton apresentou valores máximos na estação AN-03 manhã (421,2 x 103 ind/L) e tarde (45,8 x 103 ind/L). Os valores máximos registrados para protozooplâncton foram registrados nas estações AN-02 manhã em 22/10/11 (35,1 x 103 ind/L) tarde em 21/10/11 (12,6 x 103 ind/L). A partir dos dados abióticos, caracterizou-se o sistema como oligo-mesotrófico, com características distintas em seus pontos de coleta: A dominância de sarcodinos, diatomáceas e calanóides, em riqueza e densidade, demonstram o caráter estuarino, pois protozoários são indicadores de ambientes lóticos continentais, calanóides de ambientes marinhos e diatomáceas representantes de ambos os ambientes. Este estudo preliminar demonstrou a integridade ambiental do estuário, fato que reflete em sua preservação e da Mata Atlântica em seu entorno.

History of a Systematics Odyssey: The Marine Flora and Fauna of the Eastern United States

On an early fall day in September 1962 I sat quietly, thoughtfully, at my large desk in a newly renovated corner office in the old Crane wing of the Lillie Building, Marine Biological Laboratory (MBL), Woods Hole, Massachusetts. Looking out through high, ancient windows, I could see the busy main street of Woods Hole in the foreground, Martha's Vineyard beyond, behind me the MBL Stone Candle House, across the street the Woods Hole Oceanographic Institution (WHOI) and to the far right, the Biological Laboratory of the Bureau of Commercial Fisheries (BCF)(Fig. 1). Down the inner hall from my office stretched renovated quarters for the fledgling, ongoing, year-round MBL Systematics-Ecology Program (SEP), which I had been invited to direct.

Fisheries and Marine Resources of Hawaii and the U.S.-associated Pacific Islands: An Introduction

The fisheries of Hawaii and other U.S.-associated islands in the Pacific Ocean are characterized by high diversity, both in the species exploited and the human cultures that exploit them. The commercial sector has undergone rapid growth in recent years, but recreational and subsistence sectors remain important. Information on these fisheries is generally not available in published form. This paper presents an overview and introduction to a volume of papers describing fisheries in the region, with the goal of making the information available to scientists and the general public. A great deal remains to be learned about the dynamics of these fisheries as well as the associated issues in biological research, fisheries management, and environmental protection.

Hawaii's Marine Fisheries: Some History, Long-term Trends, and Recent Developments

This paper provides an overview of Hawaii's marine fisheries from 1948 to the present. After three decades of decline following a brief period of growth at the conclusion to World War lI, Hawaii's commercial fisheries began a decade of sustained development in the 1980's. At the same time, fisheries management issues became more significant as different segments of the fishery came into more direct competition. This paper provides new estimates of commercial landings for the 1977-90 period, and summarizes limited information on recreational and subsistence fisheries in the 1980's. It also provides some historical context which may be useful in evaluating fishery development and management options.

Economics and Hawaii's Marine Fisheries

This paper reviews economic research conducted on Hawaii's marine fisheries over the past ten years. The fisheries development and fisheries management context for this research is also considered. The paper finds that new approaches are required for marine fisheries research in Hawaii: A wider scope to include other marine resource and coastal zone issues, and increased and closer collaboration between researchers and the fishing community.

Travel Characteristics of Marine Anglers Using Oil and Gas Platforms in the Central Gulf of Mexico

This study was designed to evaluate the travel characteristics of avid marine anglers off Louisiana in the Central Gulf of Mexico. It focuses on the complex marine travel patterns involving the extensive assemblage of oil and gas structures. In an intercept approach, marine recreationalf isherman were asked to identify near and offshore travel patterns on the day of the interview. Information was also solicited regarding how respondents selected and located fishing destinations as well as what method of fishing was undertaken that day. Petroleum platforms were a principal fishing destination, and platform anglers traveled an average distance of 75.5 km (40.7 n.mi.) to and from offshore fishing locations. In fishing an average of 6.5 platforms per trip, these anglers traveled about 21.3 km (11.5 n.mi.) between the first and last platform visited. Mean total distances for platform anglers were 96 km (51.8 n.mi). Travel distances for bay, nearshore, and bluewater anglers were also obtained.

Disease Risks Associated with Importation of Nonindigenous Marine Animals

Transfers and introductions of marine species have occurred and are occurring on a worldwide basis, largely in response to perceived needs of expanding aquaculture industries. Greatest interest is in salmon (cage rearing and ocean ranching), shrimp, and bivalve mollusks, although other organisms are being considered. Such movements of animals carry an associated risk of moving pathogens into areas where they did not occur previously, possibly resulting in infections in native species. Many case histories of the effects of introduced pathogens and parasites now exist-enough to suggest that national and international action is necessary. Viral pathogens of shrimp and salmon, as well as protozoan parasites of mollusks and nematode parasites of eels, have entered complex "transfer networks" developed by humans, and have been transported globally with their hosts in several well-documented instances. Examining the records of transfers and introductions of marine species, incomplete as they are, permits the statement of emerging principles-foremost of which is that severe disease outbreaks can result from inadequately controlled or uncontrolled movements of marine animals.

The National Marine Fisheries Service Habitat Conservation Efforts in Louisiana, 1980 Through 1990

Data quantifying various aspects of the Corps of Engineers wetland regulatory program in Louisiana from 1980 through 1990 are presented. The National Marine Fisheries Service (NMFS) habitat conservation efforts for this time period are described and averages involved delineated. From 1980 through 1990, NMFS reviewed 14,259 public notices to dredge, fill, or impound wetlands in Louisiana and provided recommendations to the Corps on 962 projects which proposed to impact over 600,000 acres of tidally influenced wetlands. NMFS recommended that impacts to about 279,000 acres be avoided and that more than 150,000 acres of compensatory mitigation be provided. During this period, marsh management projects proposed impounding over 197,000 acres of wetlands. On a permit by permit basis, 43% of NMFS recommendations were accepted, 34% were partially accepted, and 23% were rejected.
