This book was released on 2021-07-02 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document elaborates the revised International Standard Statistical Classification of Fishing Gear (ISSCFG), as endorsed and adopted for implementation by the FAO Coordinating Working Party on Fishery Statistics (CWP) at its Twenty-fifth Session in February 2016 in Rome, Italy. The classification applies to commercial, subsistence and recreational fisheries in marine and freshwater fisheries. The document provides definitions and illustrations of the configuration and mode of operation of typical fishing gears. The primary purpose is to assist FAO Members, regional fishery bodies, as well as those working on fishery statistics and management, to correctly attribute and report fisheries catches made by different gear types. The document also contributes to the prevention, deterrence and elimination of illegal, unreported and unregulated (IUU) fishing by providing monitoring, control and surveillance personnel with information to identify the type of fishing gear with regard to licence and authorization to carry out fishing operations. Finally, the document also provides context and references for some contemporary conservation issues related to major fishing gear types; it can therefore be used as a reference text for students and researchers in fisheries and marine conservation.
Download or read book Fishing with Electricity written by K. P. Biswas and published by Daya Publishing House. This book was released on 2019 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book envisages the use of under-water electric field for catching fish. The use of electricity for catching fish has been practiced from a long time by the fishermen of different regions, the recorded evidence of which goes to 1886, when one Mr. Isham Bagg was issued a patent in Britain for catching fish with electricity. The author is the first person, who undertook fishing with electric seine as early as 1962 in Odisha, and in 2015 by developing an electric fish catcher. Originally, after several studies on fish electrophysiology, in different countries, the technique was applied in freshwater fisheries, like, streams, rivers, lakes and reservoirs, mainly for research and investigations and fisheries management. In this book, the author has tried to compile the basic principles of electrofishing system, with reference to design, construction and field application with the precautions and safety measures to be followed while construction and use of the electrofishing gear not only for the operational crews, but also for the fishes to avoid unnecessary mortality and injuries. The experiments and trial of electrofishing in sea water, particularly, of pulse trawling for flat fish, Hovercran shrimp trawling, and experiments with pelagic fishes in design criteria for electrical fish harvesting systems, which includes netless fish harvesting and mid-water electric trawling have find place in the book. The principal system components of electric fishing machine, its design consideration, power transmission, both from battery operated backpack and boat mounted electrode array and the factors affecting the efficiency of electrical fishing gear have been taken into account in the book.

Download or read book Assessment of the sustainability of fishing technologies and operations in Thailand Options for innovation written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2023-11-06 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: To make small-scale fisheries in Thailand more sustainable, fishers need to invest in responsible fishing operations and technologies, reduce overfishing, contribute to fisheries management, and implement climate change adaptation measures. The Southeast Asian Fisheries Development Center and FAO carried out an assessment of the sustainability of currently used fishing technologies and operations in Thailand, to identify options for innovation and improvements. This circular provides information on the current technological status of the Thai fishing fleets, the costs of fishing operations, the management of the main fisheries, and on the status of the main marine fisheries resources targeted by the various fishing fleets. Options for introducing technological innovations for fishing vessels include the reconfiguration of the hull by installing a bulbous bow, stabilizing fins, duct propellors and wave resistance reduction measures. On-board equipment innovations identified include hydraulic hauling systems, power blocks, refrigeration systems, fuel flow monitoring systems, solar panels, and LED lights. To improve safety, vessel owners are recommended to provide lifesaving equipment, radio communications and firefighting equipment, first aid kits, cooking and sanitation facilities, emergency stops on winches and hauling devices, lightning conductors, and distress signal devices. Fishing gear innovations such as circle hooks, low-resistance gears, turtle excluder devices, juvenile and trash excluder devices, and fish aggregating devices are also important innovations for fishing vessel owners to consider.This circular gives fishing vessel owners and financial service providers in Thailand insights in the innovations available, to make better informed fisheries investment decisions.

Book excerpt: A detailed guide of everything you want and need to know about fish. A fish is a water-dwelling vertebrate with gills that doesn''t change form, as amphibians do, during its life. Most are cold-blooded, though some (such as some species of tuna and shark) are warm-blooded. There are over 29,000 species of fish, making them the most diverse group of vertebrates. Fishing is the activity of hunting for fish. Fishing is a very ancient practice that dates back at least to the Mesolithic period which began about 10,000 years ago. Fishing is the activity of hunting for fish. By extension, the term fishing is also applied to hunting for other aquatic animals such as various types of shellfish as well as squid, octopus, turtles, frogs and some edible marine invertebrates. Fish as a food describes the edible parts of water-dwelling, cold-blooded vertebrates with gills, as well as certain other water-dwelling animals such as mollusks, crustaceans, and shellfish. An aquarium (plural aquariums or aquaria) is a vivarium, usually contained in a clear-sided container (typically constructed of glass or high-strength plastic) in which water-dwelling plants and animals (usually fish, and sometimes invertebrates, as well as amphibians, marine mammals, and reptiles) are kept in captivity, often for public display; or it is an establishment featuring such displays. A detailed guide of everything you want and need to know about fish.
