  • Current Situation, Trends and Prospects in World Capture Fisheries‘
    JUNE 1995 CURRENT SITUATION, TRENDS AND PROSPECTS IN WORLD CAPTURE FISHERIES‘ S.M. Garcia and C. Newton FAO Fisheries- Department, Rome, Italy Abstract Following an earlier analysis provided by FAO (19931, the paper gives an update of the trends and future perspectives of world fisheries. It describes and comments on worldwide trends in landings, trade, prices and fleet size. It illustrates the decrease in landings in the last 3 years, the relationship between landings and prices and the large overcapacity in world fishing fleets. It provides a review of the state of world fishery resources, globally, by region and species groups, as well as a brief account of environmental impacts on fisheries. It presents an economic perspective for world fisheries which underlines further the overcapacity and subsidy issues that characterize modern fisheries. In conclusion, it discusses‘management issues including the need for fleet reduction policies, the potential combined effect of international trade on resources depletion in developing exporting countries, throwing into question the overall sustainability of the world fishery system.

    203 Widespread infection of the Eastern red-spotted newt (Notophthalmus viridescens) by a new species of Amphibiocystidium, a genus of fungus-like mesomycetozoan parasites not previously reported in North America T. R. RAFFEL1,2*, T. BOMMARITO 3, D. S. BARRY4, S. M. WITIAK5 and L. A. SHACKELTON1 1 Center for Infectious Disease Dynamics, Biology Department, Penn State University, University Park, PA 16802, USA 2 Department of Biology, University of South Florida, Tampa, FL 33620, USA 3 Cooperative Wildlife Research Lab, Department of Zoology, Southern Illinois University, Carbondale, IL 62901, USA 4 Department of Biological Sciences, Marshall University, Huntington, WV 25755, USA 5 Department of Plant Pathology, Penn State University, University Park, PA 16802, USA (Received 21 March 2007; revised 17 August 2007; accepted 20 August 2007; first published online 12 October 2007) SUMMARY Given the worldwide decline of amphibian populations due to emerging infectious diseases, it is imperative that we identify and address the causative agents. Many of the pathogens recently implicated in amphibian mortality and morbidity have been fungal or members of a poorly understood group of fungus-like protists, the mesomycetozoans. One mesomycetozoan, Amphibiocystidium ranae, is known to infect several European amphibian species and was associated with a recent decline of frogs in Italy. Here we present the first report of an Amphibiocystidium sp. in a North American amphibian, the Eastern red-spotted newt (Notophthalmus viridescens), and characterize it as the new species A. viridescens in the order Dermocystida based on morphological, geographical and phylogenetic evidence. We also describe the widespread and seasonal distribution of this parasite in red-spotted newt populations and provide evidence of mortality due to infection.

  • Common Diseases of Wild and Cultured Fishes in Alaska
    COMMON DISEASES OF WILD AND CULTURED FISHES IN ALASKA Theodore Meyers, Tamara Burton, Collette Bentz and Norman Starkey July 2008 Alaska Department of Fish and Game Fish Pathology Laboratories The Alaska Department of Fish and Game printed this publication at a cost of $12.03 in Anchorage, Alaska, USA. 3 About This Booklet This booklet is a product of the Ichthyophonus Diagnostics, Educational and Outreach Program which was initiated and funded by the Yukon River Panel’s Restoration and Enhancement fund and facilitated by the Yukon River Drainage Fisheries Association in conjunction with the Alaska Department of Fish and Game. The original impetus driving the production of this booklet was from a concern that Yukon River fishers were discarding Canadian-origin Chinook salmon believed to be infected by Ichthyophonus. It was decided to develop an educational program that included the creation of a booklet containing photographs and descriptions of frequently encountered parasites within Yukon River fish. This booklet is to serve as a brief illustrated guide that lists many of the common parasitic, infectious, and noninfectious diseases of wild and cultured fish encountered in Alaska. The content is directed towards lay users, as well as fish culturists at aquaculture facilities and field biologists and is not a comprehensive treatise nor should it be considered a scientific document. Interested users of this guide are directed to the listed fish disease references for additional information. Information contained within this booklet is published from the laboratory records of the Alaska Department of Fish and Game, Fish Pathology Section that has regulatory oversight of finfish health in the State of Alaska.

Halibut and Sablefish harvest statewide continues to see increased harvests, The Halibut harvest is 11.8 million pounds harvested 67% of the allocation has been taken. The Sablefish IFQ harvest is at 13.8 million pounds landed, the season is 53% of the allocation has been completed; Unalaska has had 46 landings for 820, 1171bs of Sablefish. Aleutian Island Golden King Crab allocation opened on July 15th with and allocation of 7.1 million pounds we have 4 vessels registered to fish the allocation. The Eastern District allocation is set at 4.4 million pounds and has had 7 landing for and estimated total of 600,000 to 800,000 harvested. The Western District at 2.7 million pounds there have been 5 landings for and estimated 200,000 to 250,0001bs harvested. For the week ending August 17, 2019 the Groundfish landings, showed a harvest of 58,255MT landed (130million pounds) most of last week's harvest was Pollock 48, 126MT (107 million pounds).
