The By-catch From the Artisanal Shrimp Trawl Fishery, Gulf of Paria, Trinidad

Samples of shrimp trawl catches were collected from a commercial artisanal vessel fishing inside the 6-fm isobath in the Gulf of Paria, Trinidad. From August 1986 to May 1987, 34 late evening-early morning trawl trips were made and 97 hauls were sampled. Annual ratio estimates were 9 (SD 1.3) finfish:shrimp and 14.7 (SD 2.0) by-catch: shrimp, with the highest ratios observed August through December and the lowest from late January through May, the dry season. Extrapolation of ratios, using shrimp catch statistics, indicates that for 1986, 974,000 kg of finfish and 620,000 kg of crabs, Callinectes spp., were caught incidentally by artisanal shrimp trawlers fishing in the Gulf of Paria. Of this total incidental catch (1,594,000 kg), about 1,500,000 kg were discarded (94 percent). Four penaeid shrimp species are targeted: Penaeus schmitti, P. notialis, P. subtilis, and Xiphopenaeus kroyeri. Callinectes spp. were caught in large quantities from Augustto mid-January. Small (4-15 cm) pelagic and demersal species of little commercial importance dominated the finfish by-catch: Harengula spp., Cetengraulis edentulus, Chloroscombrus chrysurus, Eucinostomous spp., Diapterus rhombeus, and Cyclopsetta spp. Altogether, the monthly percentage of the species ranged from 70 to 85 percent of the total finfish by-catch.

Understanding the Market for Charter and Headboat Fishing Services

Published and unpublished research findings regarding charter and headboat fishing customers from 11 studies were reviewed to provide a marketing data base for operators and to guide further research efforts. Generally, charter/headboat fishing is a male-oriented activity. Customers were between 30 and 55 years of age. Although both groups of anglers considered themselves to be experienced, charterboat anglers had fished for more years. Charter anglers fished more often with their families and headboat anglers more often with their friends. Charterboat anglers reported higher incomes than headboat anglers. Relaxation, having fun, and escaping from daily pressures were generally more important to both groups of anglers than motives relative to catching fish. Most anglers indicated that the skills and performance of the captain and crew contributed heavily to the overall evaluation of their fishing experience. Anglers were more heavily influenced to choose a particular captain or boat by informal advertising methods (i.e., word-of-mouth recommendations, reputation, and visits to the marina) than formal methods (i.e., advertisements, brochures, radio, and television). Charter anglers relied more on word-of-mouth recommendations and headboat customers were more influenced by previous experiences. Implications for further research are discussed.

Coastal States and Distant-water Fishing Nation Relations: An Economist's Perspective

The widespread implementation of Extended Fisheries Jurisdiction (EFJ) has confronted coastal states with several resource management problems. One of these consists of the economic relations, if any, that the coastal state should establish with distant-water fishing nations (DWFN's) seeking access to the coastal state's 200-mile zone. Several of the other papers presented here deal with specific aspects of the issue. This paper, on the other hand, will concern itself with the question of the analytical framework to be used by economists in studying this issue. It will offer some suggestions with respect to possible components of the framework. In doing so, the paper will restrict itself to the coastal state's perspective of EFJ and the management issues arising therefrom. It goes without saying, of course, that an enlightened coastal state will attempt to acquaint itself with the DWFN view of the world.

Versuche zur Verringerung des Dorschbeifanges in Grundschleppnetzen

Bottom otter trawls with cut back upper panels were tested in the fischeries on Baltic Sea flounder and North Sea plaice to reduce cod by-catch. In a first series of experiments on board the fishing research cutter “Clupea” the cod-bycatch was reduced by 63 %. The catch of flounder was by 92 % higher in the cut back trawl. The same trawl with the same experimental set-up achieved aboard the fisching research vessel “Solea” on the other hand a reduction in cod-bycatch by 69 %. The catch of flounder was 23,3 % lesser in the topless trawl, which was in contrast to the “Clupea” trials. In the second series of experiments with the same cut back trawl the splits were shortened to reduce the net opening height from 0,9 m to 0,6 m previously. The cod-bycatch was reduced by 86 % and the catch of flounder was 81 % higher in comparison to the complete trawl. A prototype made of stronger net material but based on the cutting and rigging design of the tested cut back trawl with the shortened splits was tested with commercial twin trawlers. The cod-bycatch was reduced by 82,2 %, the catch of plaice by 43,3 % and the catch of dab by 44,6 % in the comparison to the commercial used trawl TV280. The flounder catch was in the topless trawl 10 % higher. In the North Sea in the comparison to a bottom trawl TV300 the cod by-catch was reduced by 89,8 %, but the catch of plaice and dab were 54 % and 58,7 % lesser. In the next step was a prototype of a normally in the North Sea plaice fisheries used trawl tested with a cut back of 2 m only. The cod catch was reduced by 16,9 % but the plaice catch, however , by 22,3 %. Kurzfassung Schleppnetze mit verkürzten Oberblättern wurden in der Fischerei auf Ostseeflunder und Nordseescholle zur Verringerung des Dorschbeifanges erprobt. In einer ersten Versuchsserie mit dem Forschungskutter „Clupea“ wurde der Dorschbeifang um 63 % reduziert. Die Fänge der Zielart Flunder waren im reduzierten Schleppnetz dagegen um 92 % höher. Das gleiche Schleppnetz mit gleichem Versuchsaufbau erzielte auf dem Fischereiforschungsschiff „Solea“ dagegen eine Reduktion des Dorschbeifanges um 69 %, wobei im Gegensatz zu den „Clupea“-Versuchen der Flunderfang um 23,3 % im reduzierten Netz geringer war. In der zweiten Versuchsserie wurden die Netzstander am reduzierten Schleppnetz verkürzt, um die Netzöffnungshöhe zu verringern. Dadurch wurde der Dorschbeifang in Versuchen mit dem Forschungskutter „Clupea“ um 86 % verringert und die Flunderfänge waren im reduzierten Schleppnetz 81 % höher. Basierend auf dem Zuschnitt des erprobten Schleppnetzes, jedoch aus stärkerem Netzmaterial gefertigt, wurde ein Prototyp auf kommerziellen Doppelnetz-Kuttern erprobt. In der Ostsee wurde in diesen Versuchen der Dorschbeifang um 82,2 %, der Schollenfang um 43,3 % und der Klieschenfang um 44,6 % mit dem im Oberblatt verkürztem Schleppnetz im Vergleich zum Kutterschleppnetz TV280 reduziert. Der Flunderfang war im reduzierten Schleppnetz 10 % höher. Auf der Nordsee wurde mit diesem Versuchsnetz im Vergleich zu einem TV 300 der Kabeljaubeifang um 89,8 % verringert, die Schollenfänge waren jedoch 54 % geringer und die Klieschenfänge 58,7 % geringer als im Vergleichsnetz. In einer weiteren Variante wurde ein in der Nordseeschollenfischerei verwendetes Grundschleppnetz mit 2 m geringfügig im Oberblatt zurückgeschnitten und mit dem Prototyp auf einem Doppelnetz-Heckschlepper verglichen. Der Kabeljaubeifang wurde dadurch um 16,9 % der Schollenfang aber um 22,3 % verringert

Climate change and fisheries: perspectives from small-scale fishing communities in India on measures to protect life and livelihood

Through consultations with key fisheries-based stakeholders in four States of India, this study attempts to assess perceptions of fishing communities about the impact of climate change on their lives and livelihoods. It also evaluates the traditional knowledge, institutions and practices of fishing communities that are relevant to climate-change preparedness. The study identifies adaptation and mitigation measures that may need to be adopted by fishing communities and the State in relation to climate change. Based on this overall analysis, the study proposes measures to protect the lives and livelihoods of small-scale fishing communities in the context of climate-change policies and programmes at different levels. This study will be useful for researchers, policymakers, students and anyone interested in climate change and its potential effects on the lives and livelihoods of small-scale fishing communities.

Reserved parking : marine reserves and small-scale fishing communities: a collection of articles from SAMUDRA report

As the earth’s resources continue to face increasing pressure from a variety of human and natural causes, protection of the environment and biodiversity is a matter of contemporary concern, The conservation of coastal and marine resources, in particular, has become a priority for countries around the world. In this context, marine protected areas (MPAs) are being widely promoted as one of the most effective tools for the conservation of coastal and marine resources. Most MPAs are located in coastal areas of great biodiversity, and hence their development has direct impacts on the lives and livelihoods of coastal communities, especially small-scale and traditional fishing communities. Typically, they are the ones who have to bear the costs of conservation practices–lost livelihood options, expulsion from traditional fishing grounds and living spaces, and violation of human/community rights, to name a few. The articles in this dossier, drawn chronologically from the pages of Samudra Report, the triannual publication of ICSF, draw attention to these issues. They show that conservation and livelihoods are closely intertwined, and that top-down, non-participatory models of conservation can be counter-productive. Despite being poor and powerless, fishing and coastal communities can be powerful allies in conservation efforts, given their longstanding dependence on natural resources and their traditional ecological knowledge systems. As the examples in this dossier reveal, it is possible for fishing communities to protect and conserve the environment, while continuing with sustainable fishing operations. Clearly, only an integrated approach to fisheries management and conservation will prove successful. This dossier will be useful for policymakers, social scientists, non-governmental organizations and others interested in fisheries, conservation, communities and livelihoods.
