salmonid freshwater Fisheries Statistics england wales 1990
1992Co-Authors: I C RussellAbstract:This is the Salmonid & Freshwater Fisheries Statistics for England & Wales 1990 produced by the National Rivers Authority (NRA) in 1992. This report is focused on the maintenance, improvement and development of Fisheries of England and Wales. This report is the second compilation of salmon and migratory trout catch Statistics for England and Wales published by the National Rivers Authority (NRA). Before 1989, these Statistics were published by the Ministry of Agriculture Fisheries and Food (MAFF) Directorate of Fisheries Research in their Data Report Series. The 1990 data have been presented in a broadly similar format to those of 1989. However, two further NRA regions, four in all, provided effort data for rod Fisheries in 1990. This report makes a general review of different catches: Northumbria, Yorkshire, Anglian, Thames, Southern, Wessex, South West, Severn-Trent, Welsh and North West.

Puerto Rico’s small scale commercial Fisheries Statistics during 2004-2006
2007Co-Authors: Daniel Matos-caraballo, Jesus Leon, Hector Y. Lopez, Albaliz Mercado-porrata, Luis A. Rivera, Lucia T. VargasAbstract:The Fisheries Research Laboratory (FRL) of the Puerto Rico Department of Natural and Environmental Resources (DNER) monitors the commer-cial landings of fish and shellfish in Puerto Rico. The Commercial Fisheries Statis-tics Program (CFSP) was implemented in 1967 under the Commercial Fisheries Research and Develop-ment Act of 1964 (PL 88-309) to collect data on the commercial fishery. Currently, this project is funded by the NOAA/National Marine Fisheries Service (NMFS) through the State/ Federal Cooperative Fisheries Program, Interjuris-dictional Fisheries Programs and the DNER. The CFSP includes the following objectives: commercial Fisheries landings reports, collection of bioStatistics data, enter the collected data in computer format and estimate catch per unit effort (CPUE). The CFSP reached all the objectives during 2004 - 2006. A total of 1.86 millions pounds were reported in 2004, 1.57 millions pounds in reported in 2005, and 1.34 millions reported pounds were reported in 2006. The CFSP determined a correction factor to estimate the non reported landings. Using the correction factor of 61% for 2004 has been estimated that a total of 3.06 millions of pounds were landed in Puerto Rico. In 2005, the correction factor was 50%, a total of 3.1 millions pounds landed. In 2006, a correction factor was 52%, a total of 2.6 millions pounds were landed. BioStatistics data of fish and lobster were collected. BioStatistics data were obtained from a total of 54,685 organisms during 2004 - 2006. All data were entered in computers and sent to NOAA/Southeast Fisheries Science Center, at Miami, FL. The CPUE for landings and bioStatistics data were estimated and are presented in this report. Also the paper shows data from landings by species, by coast and by municipality. Comments about the implementation of the new Fishing Regulation to conserve fishery resources and the impact in commercial fishers and their behavior are also presented in this paper.

overview of puerto rico s small scale Fisheries Statistics 2001 2004
2004Co-Authors: Daniel MatoscaraballoAbstract:The Fisheries Research Laboratory (FRL) of the Puerto Rico Department of Natural and Environmental Resources (DNER) monitors the commercial landings of fish and shellfish in Puerto Rico. Using the correction factor of 86% to estimate the under reported landings data in Puerto Rico during 2002, it was estimated that a total of 3,805,595 pounds of fish and shellfish were landed, with a market value of $7,877,582. Raw data shows that for 2002 a total of 3,272,812 pounds was reported. The landings estimate for Puerto Rico during 2003, using the correction factor of 56% was 4,265,645 pounds of fish and shellfish, with a wholesale market value of $7,848,786. The raw data shows that for 2003, the landings reported were 2,388,761 pounds. The landings estimate for Puerto Rico during 2004 using the correction factor of 61%, was 3,056,852 pounds of fish and shellfish, with a wholesale market value of $7,519,857. The raw data indicates that for 2004, the landings reported were 1,864,680 pounds. The most important fish, in terms of percentage of total pounds landed (fish and shellfish), for 2002 - 2004, was the yellow-tail snapper (Ocyurus chrysu-rus) 8.2%, silk snapper (mainly Lutjanus vivanus ) 6.4%, various species of grunts mainly the white grunt (Haemulon plumieri) 4.6%, lane snapper (Lutjanus synagris) 4.2%, various species of tuna 4.2%, mackerel species (Scomberomorus cavalla) 3.3%, dolphin-fish (Coryphaena hippurus) 3.2%, various species of parrotfish 3.0%, various species of trunkfish 2.5% and red hind (Epinephelus guttatus),reported 2.3%. The most important of the shellfish species were the spiny lobster (Panulirus argus) 10.0% and the queen conch (Strombus gigas) 8.5%. The gear types, which accounted for the highest percentage of landing, by weight during 2002 - 2004, were bottom lines 30.0% of the total catch. Bottom lines were followed by fish traps that accounted for 20.3% of the total reported catch . Fish traps were followed by SCUBA divers that fished 19.6% of the total reported catch. A total of 62,990 finfish and spiny lobsters were measured to collect biostatistical data during 2002 - 2004. Sex determi-na-tion of fishes in the field has been difficult because of the reluc-tance of fishers to permit this activity, and the general limita-tion in available time for measuring samples. The species most frequent-ly measured from 2002 - 2004 were Ocyurus chrysurus, Haemulon plumieri, Lutjanus vivanus, Sparisoma viride, Panulirus argus, Sparisoma chrysop-terum, Epinephelus guttatus, Scomberomorus cavalla and Lutjanus synagris. A total of 519 fishing trips were interviewed to collect biostatistical data in 2002, 578 interviews in 2003, and 723 interviews in 2004.

FAO Fisheries and Aquaculture Circular No . 1034 A REVIEW ON CULTURE , PRODUCTION AND USE OF SPIRULINA AS FOOD FOR HUMANS AND FEEDS FOR
Aquaculture, 2008Co-Authors: M. Habib, M; Parvin, M.; Huntington, T.; HasanAbstract:Spirulina are multicellular and filamentous blue-green microalgae belonging to two separate genera Spirulina and Arthrospira and consists of about 15 species. Of these, Arthrospira platensis is the most common and widely available spirulina and most of the published research and public health decision refers to this specific species. It grows in water, can be harvested and processed easily and has significantly high macro- and micronutrient contents. In many countries of Africa, it is used as human food as an important source of protein and is collected from natural water, dried and eaten. It has gained considerable popularity in the human health food industry and in many countries of Asia it is used as protein supplement and as human health food. Spirulina has been used as a complementary dietary ingredient of feed for poultry and increasingly as a protein and vitamin supplement to aquafeeds. Spirulina appears to have considerable potential for development, especially as a small-scale crop for nutritional enhancement, livelihood development and environmental mitigation. FAO Fisheries Statistics (FishStat) hint at the growing importance of this product. Production in China was first recorded at 19 080 tonnes in 2003 and rose sharply to 41 570 tonnes in 2004, worth around US$7.6 millions and US$16.6 millions, respectively. However, there are no apparent figures for production in the rest of the world. This suggests that despite the widespread publicity about spirulina and its benefits, it has not yet received the serious consideration it deserves as a potentially key crop in coastal and alkaline areas where traditional agriculture struggles, especially under the increasing influence of salination and water shortages. There is therefore a role for both national governments as well as intergovernmental organizations to re-evaluate the potential of spirulina to fulfill both their own food security needs as well as a tool for their overseas development and emergency response efforts. International organization(s) working with spirulina should consider preparing a practical guide to small-scale spirulina production that could be used as a basis for extension and development methodologies. This small-scale production should be orientated towards: (i) providing nutritional supplements for widespread use in rural and urban communities where the staple diet is poor or inadequate; (ii) allowing diversification from traditional crops in cases where land or water resources are limited; (iii) an integrated solution for waste water treatment, small-scale aquaculture production and other livestock feed supplement; and (iv) as a short- and medium-term solution to emergency situations where a sustainable supply of high protein/high vitamin foodstuffs is required. A second need is a better monitoring of global spirulina production and product flows. The current FishStat entry which only includes China is obviously inadequate and the reason why other countries are not included investigated. Furthermore, it would be beneficial if production was disaggregated into different scales of development, e.g. intensive, semi-intensive and extensive. This would allow a better understanding of the different participants involved and assist efforts to combine experience and knowledge for both the further development of spirulina production technologies and their replication in the field. A third need is to develop clear guidelines on food safety aspects of spirulina so that human health risks can be managed during production and processing. Finally, it would be useful to have some form of web-based resource that allows the compilation of scientifically robust information and Statistics for public access. There are already a number of spirulina-related websites (e.g. www.spirulina.com, www.spirulinasource.com) whilst useful resources, they lack the independent scientific credibility that is required.
