SPC Fisheries Newsletter #105 — April/June 2003 SPC ACTIVITIES Provided As Customary Acknowl- Edgement to Dignitaries, Or Eaten by the Crew Number 105 (April–June 2003) ISSN 0248-076X Welcome to the latest issue of the SPC Fisheries Newsletter.I would like to draw your attention to the recent SPC publication "Horizontal Longline Fishing manual". The main purpose of this manual is to introduce the horizontal longline fishing method to Pacific Island fishermen,and assist those currently SPC activities Page 2 involved to improve their fishing success,particularly in commercial or semi- commercial situations. This manual is intended to act as a guide to the principles and techniques of good horizontal tuna longline fishing.Environmental and conservation issues and concerns have also been included to raise News from in and around awareness and to present ways to minimise impacts on unwanted species the region Page 15 or the environment as a result of horizontal tuna longline fishing activities. Michel Blanc presents on page 33 the results of the review of the SPC/Nelson Polytechnic Pacific Island Fisheries Officers Training Course. FAD Research Project: Summary It was considered essential by fisheries administrations that a of results at the end of the second comprehensive review be undertaken, with regards to the major changes fisheries in the Pacific have undergone over the last two decades with the year (June 2003) development of subsistence, artisanal and industrial sectors. by Lindsay Chapman, Ian Bertram Jean-Paul Gaudechoux and Brendon Pasisi Page 19 Fisheries Information Adviser ([email protected]) Aquaculture update for Vanuatu by Ben Ponia Page 27 Conservation through cooperation – The seabird bycatch issue in New Zealand by Alec Woods Page 31 SPC/Nelson course freshened up by Michel Blanc Page 33 The long awaited tuna longline has now been printed.

The first sessions covered the different tools and fishing gear to be used during the project, and the theory of the fishing technique. Participants were then divided into three groups for practical training. Each group completed two, six- week-long fishing trips. In total, 40 sets were made of the 200- hook longline over 26 fishing days. As the longline was short, two sets were generally made per day, one in the morning and one in the evening.

The FV Wa-Bal, was assessed as being marginally suitable as a tuna longline vessel, provided several improvements to work- ing conditions were made. The stability of the vessel in moder- ate to rough sea conditions needs to be improved. The elec- trical system on the vessel needs modifying, including the installation of a small generator to keep the batteries charged. Another limiting factor is the small size of the fish hold which hold around 1.5 to 2 mt of fish Cleaning the fish hold on FV Wa Bal in ice.

Once the sites were identified, three FADs were rigged, two spar buoys and one modified Indian Ocean design. Two FADs were rigged for 2500 m and the other for 1500 m, allowing for a 20 per cent scope in the rope length. All the materials for the three FADs, including three tonnes of 16 cm reject mooring chain for use as FAD anchors, were loaded onto a barge for deploy- ment.

    6.0 DESCRIPTION OF THE PELAGIC LONGLINE FISHERY FOR ATLANTIC HMS The HMS FMP provides a thorough description of the U.S. fisheries for Atlantic HMS, including sectors of the pelagic longline fishery. Below is specific information regarding the catch of pelagic longline fishermen in the Gulf of Mexico and off the Southeast coast of the United States. For more detailed information on the fishery, please refer to the HMS FMP. 6.1 Pelagic Longline Gear The U.S. pelagic longline fishery for Atlantic HMS primarily targets swordfish, yellowfin tuna, or bigeye tuna in various areas and seasons. Secondary target species include dolphin, albacore tuna, pelagic sharks including mako, thresher, and porbeagle sharks, as well as several species of large coastal sharks. Although this gear can be modified (i.e., depth of set, hook type, etc.) to target either swordfish, tunas, or sharks, like other hook and line fisheries, it is a multispecies fishery. These fisheries are opportunistic, switching gear style and making subtle changes to the fishing configuration to target the best available economic opportunity of each individual trip. Longline gear sometimes attracts and hooks non-target finfish with no commercial value, as well as species that cannot be retained by commercial fishermen, such as billfish. Pelagic longline gear is composed of several parts. See Figure 6.1. Figure 6.1. Typical U.S. pelagic longline gear. Source: Arocha, 1997. When targeting swordfish, the lines generally are deployed at sunset and hauled in at sunrise to take advantage of the nocturnal near-surface feeding habits of swordfish. In general, longlines targeting tunas are set in the morning, deeper in the water column, and hauled in the evening.

  • RECREATIONAL FISHING GEAR Setline - Longline
    RECREATIONAL FISHING GEAR Setline - Longline Marker buoys Main line Branch line (snood) Buoy line Hook Anchor weight Gear Description A longline is a setline which is set horizontally on the sea floor. It consists of four main parts; the main line, branch lines (or snoods), hooks and bait. Other components are marker buoys or dhan poles, the buoy line, anchor weights, swivels and clips. The longline is set with an anchor weight at each end. The branch lines are clipped at regular intervals onto the main line. They consist of a shark clip with a short length of braided line tied to a sharp, heavy gauge circle or double hook. Buoy lines and surface marker buoys at each end help the fisher to locate and retrieve the long line. Additional buoys and a dhan pole and flag may also be attached to increase the visibility of the longline for the fisher and other boats. A GPS fix may also assist when locating gear. How it works Longlines are set by attaching snoods to a weighted mainline while the boat is moving so that it lies along the sea floor. As the longline settles on the sea floor, scent from the baits attracts shark and fish to the hooks. Movement of the baits due to the current further entices fish. Squid or octopus tend to be the preferred bait because the leathery texture increases the ability of the bait to stay on the hooks. Fresh scalefish such as jack mackerel and Australian salmon are popular alternative baits. Wild Fisheries Management Branch Department of Primary Industries, Parks, Water and Environment Recreational Fishing Gear Longline Target Fish In Tasmania, longlines are primarily used to target school and gummy shark.

    3.1.2 LONGLINE CHAPTER 3.1.2: AUTHORS: LAST UPDATE: LONGLINE Domingo A., Forselledo R., Miller March 2014 P., Jiménez S., Mas F. and Pons M. 3.1.2 General description of longline fisheries 1. General description of longline gear and vessels Longline is a fishing gear that is comprised of a main line, with secondary lines attached and hooks placed on the end of them. Longline is a very old gear, derived from “volantín” or “three hook line”, which was used by the Phoenicians and the Egyptians in the Mediterranean Sea (Canterla, 1989). The word “longline” is possibly of Catalonian origin, and derived from southern Italian or Greece (Prat Sabater, 2006; González García, 2008). Since their beginnings and up to the 15th century at least, the longlines that were used were fixed, anchored to the coast with stalks. Later, in the open sea, “jeito” and “vareque” net gears were used which drifted while remaining moored to the vessels, and which could have given rise to drift gears, one of which is longline (Canterla, 1989). 1.a General description of pelagic longline 1.a.1 Introduction Drifting pelagic longline is used worldwide to catch widely distributed pelagic and semi-pelagic fish. This gear is very effective in catching tunas, billfish and sharks, among others (Doumenge, 1998; Matsuda, 1998). It consists of a main line or “mother” line, suspended in the water by secondary lines called float lines, which carry the floats. The branch lines hang from the main line and carry hooks on the ends. The characteristics of the materials, dimensions, types of floats and hooks, as well as the configuration of the lines are quite variable, depending mainly on the origin of the fleets, the fishermen and the target species.

More than half of the individuals (55 %) were observed swimming toward the bait and then turning around or tasting it without performing any attacks. These observations showed that individual fish motivation and behaviour are important factors in determining whether European catfish are attracted to bait and eventually hooked. Keywords: Bait, fishing, predation, river, top predator, video. INTRODUCTION Throughout history people have developed techniques to capture animals. Among these techniques the use of baits has been widespread.
