The specimen was female and obtained during an otter trawl survey on 4 April 2013 in the East China Sea (31852.16′N 127842.94′E) at a depth of approximately 140 m on the slope of the continental shelf. Morphometric measurements and meristic counts are reported in this paper. We also report profiles of water temperature, salinity, dissolved oxygen and chlorophyll-a taken immediately prior to the trawl, and species composition of concurrent catch with the otter trawling as environmental and biological characteristics of the habitat.

  • Description of the Biology and an Assessment of the Fishery for Adult
    94 NSW Dept of Primary Industries 3. COMMERCIAL FISHERIES Bruce Pease and Trudy Walford - NSW Dept of Primary Industries 3.1. Introduction In this report, the harvest of any life history stage of naturally occurring longfinned eels for commercial profit is considered to constitute a commercial fishery. The eels may be sold for direct consumption or may be sold to the aquaculture industry for further grow-out and value-adding. Any translocation of naturally occurring eels for further growth and later harvest for commercial profit is also considered to be a commercial activity. Harvest of a range of life-history stages for an increasing range of markets has lead to a complex set of commercial fisheries and related catch and effort reporting systems for river eels in NSW. Based on the following comments by Roughley (1955), who was Superintendant of NSW Fisheries from 1939 to 1952, it is apparent that there were no commercial eel fisheries in NSW prior to 1955: “In view of the fact that there is so little demand for eels in Australia they can be viewed only as being in the nature of pests, for they destroy large quantities of fish that are appreciated by the public and, when occurring in streams containing trout, they prey on these valuable sporting fish extensively. In North Gippsland farmers who endeavour to raise ducks are pestered by eels, which bite off the legs of the ducklings when swimming or drag them to the bottom to consume them. Although found in greatest abundance in fresh water, eels sometimes occur in considerable concentrations in the brackish water of estuaries, where they may interfere seriously with the operations of net fishermen.” The first reported commercial landings of eels in NSW appear in the annual Report of the Chief Secretary on Fisheries in New South Wales for the Year Ended 30th June, 1970 (Pease and Grinberg 1995).

  • 1 Apresentação
    1 1 APRESENTAÇÃO O presente produto faz uma análise do meio ambiente marinho existente na área do Parque Estadual Marinho da Pedra da Risca do Meio e arredores. Este produto (4-diagnóstico ambiental) é uma etapa fundamental para poder elaborar ações de fiscalização e gestão para poder conservar o parque. Assim, este produto visou entender os principais componentes do ambiente local como a vida marinha, as características físicas e químicas do mar, a existência de poluição e impactos humanos na área bem como compreender os atores principais que realizam atividades na área como mergulhadores e pescadores. Para isso, foram realizadas atividades embarcadas por dez dias no mar bem como atividades em terra que incluíram análises nos laboratórios e questionários aos pescadores e mergulhadores. O Produto 4 do Projeto de elaboração do plano de manejo do Parque Estadual Marinho da Pedra da Risca do Meio (PEMPRIM) consiste em um documento técnico-científico de diagnóstico dos aspectos bióticos, abióticos e socioeconômicos do Parque. Para tanto, foram realizados dez dias de embarque (ver datas, fotos e atividades da apresentação nos ANEXOS) à área da unidade à bordo da embarcação Argo Equatorial – Labomar/UFC, assim como entrevistas com a comunidade de pescadores e mergulhadores que utilizam a região do Parque. Dessa forma, neste diagnóstico serão abordados aspectos relacionados à biodiversidade marinha (bentos, plâncton e nécton), oceanografia física (correntes, ondas e marés), oceanografia geológica (batimetria, sedimentologia, caracterização geológica
