PREFACE In September 1993, W. Douglas Souter was contracted by Agricultural Cooperative Development International of Washington, D.C., USA in cooperation with the Asociacion de Exportadores of Lima, Peru to conduct an overview of vessels engaged in the fishing industries of Peru. The project required Mr. Souter to travel to Peru, visit the ports of Caleta Cruz, Paita, Chimbote and Ilo, note operational shortcomings of vessels and their equipment where observed and recommend improvements that may benefit vessel owners and the overall fishing industry. The time allocated for this overview did not permit an in­ depth survey of individual vessels. Therefore, interviews with vessel owners and fleet managers, coupled with previous experience and knowledge of the characteristics of Peruvian fishing vessels were used to compile this report. 2 II. PROJECT OBJECTIVES 1. To evaluate the Peruvian fishing fleet to determine the characteristics required for vessels to engage in harvesting Peruvian pelagic resources of demersal mid-water and surface species, with emphasis to be directed at the harvesting of jurel and caballa. 2. Vessel refrigeration. 3. Vessel sanitation. 4. Renovation of the current fleet of purse seine vessels. 5. New techniques and equipment available for the capture of under-exploited species. The following sections deal with each of the objectives. However, because there are no new techniques for the capture of the under-exploited species of pelagics, jurel, caballa and merlusa, the mid-water and bottom two-vessel trawl systems are emphasized. 3 III. EXECUTIVE SUMMARY 0 In 1991, from a combined biomass of over 7,000,000 tons and a permissible catch of 1,600,000 tons, only 140,000 tons of jurel and caballa were captured by Peruvian vessels. 0 To harvest jurel and caballa in greater quantities, the mid­ water trawling techniques must be employed. * During the period January 1 through October 31, 1991, only 75,000 tons of merlusa were landed (from a permissible catch of 150,000 tons) by a small fleet of bottom trawlers operating from the port of Paita. • A combined total of 5,340,000 tons of mixed anchoveta, sardina, jurel and caballa was landed by 383 operational Peruvian purse seine vessels in 1991. Non-operating vessels were reported to total 275. * A vessel's age is not the determining factor governing its suitability for continued operations; rather it is how it has been maintained, because purse seine vessels and their basic equipment have changed little during the past 25 years. At least 50 percent of the vessels engaged in purse seine fishing in Canada and the United States are over 30 years of age. • The operational section of the Peruvian purse seine fleet is equal to or better than those engaged in similar fisheries in other parts of the world. 0 Very few Peruvian purse seiners are insulated or have refrigeration systems. • It is recommended that insulation and refrigerated sea water systems be installed in vessels that offload to facilities that 4 process sardina, jurel and caballa for human consumption or for the manufacture of high-protein fish meal. 0 Bird radars are recommended for Peruvian purse seine vessels as a valuable fishing aid. 0 The merlusa bottom trawl fleet is operating as well as can be expected, given the size and power of the vessels and their equipment. 0 Fish holds of the fleet lack adequate insulation or have none. • Quality of the raw product could be improved if merlusa were chilled when caught and bruising was avoided by not overfilling trawls. 0 All bottom trawl vessels should carry adequate ice or install refrigerated sea water (RSW) or chilled sea water (CSW) systems. 0 Two-vessel bottom pair trawling could be more productive than the current one-vessel system being employed for harvesting merlusa. * Vessels currently engaged in the bottom trawl fishery could convert to conduct pair trawling operations at reasonable costs, including insulation and/or RSW or CSW. * Additional electronics are recommended regardless of which technique is being employed. The most important items are net sounders with rectifiers, global plotting systems with track plotter and ram cars, and sonar units. • Trawl nets or plans for nets should be purchased from Europe. 5 0 A project to determine the viability of the pair trawl system in Peru should be conducted using European fishermen to demonstrate the techniques. • The benefits visualized by using the pair trawl system for harvesting merlusa are: 1. Eliminate the necessity of investing in costly high­ powered vessels to increase production. 2. Allow some of the smaller anchoveta vessels to enter the fishery. 3. Keep the fishery in the hands of existing Peruvian vessel owners. 4. Allow the merlusa trawlers to also participate in the harvesting of offshore jurel and caballa populations. 0. Mid-water trawling for harvesting herring, jurel and other subsurface species is practiced in other areas of the world. • Russian and Cuban mid-water trawlers operating in Peruvian waters from 1983 through 1991 captured an average of 12,000 tons of mixed jurel and caballa per vessel per year. o Single mid-water trawl vessels are more costly to build and operate than the pair trawl units and are not recommended. * Mid-water pair trawling is recommended for a jurel/caballa fishery providing raw material prices can support a fishery. • Refrigeration systems and the use of ice all have good and possible bad features. 6 * Peru should adopt portions of the Canadian vessels sanitary regulations that apply to Peruvian vessels. 0 Financing the renovation of inactive vessels in the Peruvian purse seine fleet presents a dilemma because allowable catches are currently being harvested by the active fleet. W The merlusa fishery of Paita and possibly a jurel/caballa mid-water trawl fishery may be able to absorb some of the older Peruvian purse seine vessels. 7 IV. BACKGROUND Large populations of anchoveta, sardina, jurel, caballa and merlusa lie in close proximity to the Peruvian coast. Currently the harvesting of anchoveta, sardina, and to a lesser extent, jurel and caballa, is carried out by vessels using purse seines. This technique is employed to capture many species that inhabit the upper layer of the world oceans to a depth of about 35 fathoms. It has been practiced in Peru for the harvesting of anchoveta since the early 1960's and later for sardina, jurel and caballa. The fishery is well developed, but many of the older vessels involved are in very poor condition and need renovation or replacement. Although jurel and caballa are seasonally harvested by the use of purse seines in shallow coastal waters, the largest portion of these populations is found in deeper water and beyond the reach of purse seine nets. In 1991 from a combined biomass of over 7,000,000 tons and a permissible catch of 1,600,000 tons, only 140,000 tons were captured by Peruvian vessels. In order to capture the deep-swimming populations of these species, it will be necessary to employ the mid-water trawling technique that has proven to be effective at depths of 35 to more than 100 fathoms. There are currently no mid-water trawlers operating in Peruvian waters. Merlusa that inhabit the ocean bottom areas

Vessel types: Pair trawlers In the wet-fish trawler the fish is kept in the hold in the fresh/"wet" condition. Characteristics Midwater pair trawling Species Environment Midwater pair trawling can be effective in different situations: when fish are aggregated into large dense shoals and when (at another season or time of the day or according to physiological status) fishes are regularly distributed within a given water layer. In addition to the difference it makes whether the FAO Fisheries and Aquaculture Department fish are aggregated in a small volume or spread within a large one, fish may swim (and avoid the net) at different speeds according to its own physiological status and/or other external conditions. As a result, in addition to the fish which is targeted, other different conditions will affect the design and size of the midwater trawl, as well as the towing speed. Fishing Gear A midwater pair trawl has roughly similar design as other midwater trawls. Midwater pair trawls might, however, be designed to have a more rectangular opening than ordinary midwater otter trawls. Midwater pair trawls might be rigged with two towing warps from each vessel or alternatively with one towing warp from each vessel and a bridle arrangement.

  • European Trawlers Are Destroying the Oceans
    EUROPEAN TRAWLERS ARE DESTROYING THE OCEANS Introduction Nearly 100,000 vessels make up the European Union fishing fleet. This includes boats that fish both in EU waters (the domestic fleet), in the waters of other countries and in international waters (the deep-sea fleet). In addition, there is an unknown number of vessels belonging to other European countries that are not members of the EU which could approach a figure half that of the EU fleet. The majority of these vessels sail under the flag of a European country but there are also boats, particularly those fishing on the high seas, which despite being managed, chartered or part owned by European companies, use the flag of the country where they catch their fish or sail under flags of convenience (FOCs). The Fisheries Commission has called for a reform of the Common Fisheries Policy (CFP) to achieve a reduction of 40% in the EU fishing capacity, as forecasts show that by simply following the approved multi-annual plans, barely 8.5% of vessels and 18% of gross tonnage would be decommissioned1; an achievement very distant from scientific recommendations. Moreover, from among these almost 100,000 vessels, the EU is home to a particularly damaging fleet: the 15,000 trawlers that operate in European waters, as well as those of third countries or those fishing on the high seas. These trawlers are overexploiting marine resources and irreversibly damaging some of the most productive and biodiverse ecosystems on the planet. The 40% reduction called for by the Commission could be easily achieved if the primary objective of this proposal was focused both on eliminating the most destructive fishing techniques and reducing fishing overcapacity.

  • How Fish Are Caught
    How fish are caught Wild fish can be caught in a variety of different ways, from the traditional rod and line to traps and trawl nets large enough to capture a passenger airplane. Fishing gears can be categorized as either mobile/active or static/passive depending on whether they are towed across the seabed or fixed to it. Mobile/active gear includes any trawls, trolling and drifting nets or lines whereas static/passive gear includes fixed nets, traps and rod and line. Generally static /passive gear has a lower impact on the seabed. Here are the most commonly used fishing methods with a brief explanation of how they work and their environmental impacts. Beam trawl In this type of trawl, the mouth or opening of the net is kept open by a beam, which is mounted at each end on guides or skids which travel along the seabed. The trawls are adapted and made more effective by attaching tickler chains (for sand or mud) or heavy chain matting (for rough, rocky ground) depending on the type of ground being fished. These drag along the seabed in front of the net, disturbing the fish in the path of the trawl, causing them to rise from the seabed into the oncoming net. Electrified ticklers, which are less damaging to the seabed, have been developed but used only experimentally. Work is also being carried out to investigate whether square mesh panels (see below) fitted in the ‘belly’ or lower panel of the net can reduce the impact of beam trawling on communities living on or in the seabed.

  • Title: an Alternative Design of Trawls for Off-Shore Fishing in Vietnam
    PO Box 1390, Skulagata 4 120 Reykjavik, Iceland Final Project 2001 AN ALTERNATIVE DESIGN OF TRAWLS FOR OFFSHORE FISHING IN VIETNAM Tran Duc Luong Nha Trang University of Fisheries Vietnam [email protected] Supervisors: Mr. Jon Thordarson, University of Akureyri, Iceland [email protected] Mr.Einar Hreinsson, Netagerd vestfjarda HF [email protected] ABSTRACT This study deals with designing an alternative fishing gear for Vietnamese fisheries. It looks at both pair trawl and single trawl with doors for fishing in Vietnam seawater at depth 100 – 300 m. The study used a combination of knowledge pertaining to similarity method and experimental method in trawl designing. Although there is no exact design theory, similarity method gives a sound knowledge for designing trawl net better than experimental knitting method, which is commonly used by Vietnamese fishermen. As the designer has to be creative in each particular case, and the effectiveness of fishing gear so developed depends heavily on the knowledge acquired from fishermen and on information on bottom conditions and fish behaviour, This study could be used as an effort of trial and balance for further work in this direction. It leads to rational decisions regarding future development of suitable trawls for Vietnamese deep-sea fishery. Tran TABLE OF CONTENTS 1.

Nearshore marine habitats in Sussex are vital fish breeding, feeding and nursery grounds for many commercial fish species. They are essential fish habitats. Continued use of bottom towed trawling gear in the nearshore environment is not sustainable if these valuable areas are to be protected. Why is Government intervention necessary? The nature of fisheries means that without public sector intervention, most stocks would be overfished. Sussex IFCA considers that commercial pressures would lead some trawlers to pursue stocks in the area and damage the provision of public goods and services in the marine environment. What are the policy objectives and the intended effects? The policy objective is to review and update the current ‘Trawling Exclusion Byelaw’ (made in 1997 and confirmed in 1998) according to best available evidence, and to implement fisheries management measures that best protect the natural capital assets within the Sussex nearshore area.

Ávila-da-Silva2 1São Paulo State University - UNESP, Biosciences Institute of Rio Claro, SP, Brazil 2Instituto de Pesca, Centro APTA do Pescado Marinho, Santos, São Paulo, Brazil Corresponding author: Antônio O. Ávila-da-Silva ([email protected]) ABSTRACT. In 2008, the government of the São Paulo State, Brazil, established marine protected areas (MPAs) along its entire coast. Pair trawling was banned from most of these areas ever since. This study investigated how these MPAs influenced on pair trawling fleet's operational patterns and landings from 2005 to 2012 as well as on the other fleets dynamics. Landings of pair trawlers per unit effort remained stable, however, they had to look for farther fishing grounds and capture deeper and less profitable species, changing their landing composition and reducing income. Gillnet fleet, particularly, has intensified fishing in MPAs and showed an increase in catches of some species that was once targeted by pair trawlers. In this case, MPAs management acted more towards a territorial management, protecting artisanal fisheries, than in the protection of fisheries resources.
