Résumé :

Sharks is the dominant bycatch of purse seine and bottom longline vessels that landed in Kutaraja ocean fishing port, particularly pelagic thresher shark species (Alopias pelagicus). The management of shark fisheries in Aceh water is not well implemented. According to the IUCN red list, the pelagic thresher shark has been classified as an endangered species. The capture and trade of pelagic thresher sharks are regulated by CITES (Appendix II). So that Indonesia has to comply with the procedures of CITES due to it has been adopted through the Decree of Minister of Marine Affairs and Fisheries o

Résumé :

Mamuju Regency, West Sulawesi Province, has the potential for pelagic fish, especially large pelagic fish, namely tuna, skipjack and cob, which are very prospective. The majority of fishermen in Mamuju Regency use fishing rods to catch large pelagic fish. Fishing rod fishermen with a large pelagic catch target are in Mamuju Regency, Simboro District, precisely in Sumare Village but currently it is known that there has been a decrease in the number of fishing rod fishermen in Mamuju Regency since the last 5 years experiencing a decrease in production.

Résumé :

Ecosystem-based fishery management (EBFM) requires minimizing the risk of irreversible change to a natural assemblage of species. Because pelagic fisheries modify the biotic community rather than the physical environment and often target migratory species, the pelagic community can be expected to respond quickly after fishing pressure is reduced. We monitored the pelagic zooplanktivore community over 4 decades in the central Bering Sea before and after the closures of large-scale pelagic fisheries. We found a quick and steep change in the pelagic fish community structure after fishing pressure

Abstract Predators often predate on a limited size range of prey, which may or may not overlap with size ranges of same prey targeted by fisheries. When they do overlap, the effect of competition over that prey is immediate, as the predator removes prey, which are at the same time suitable for the fishery. However, if the predator consumes the same prey species as the fishery, but targets smaller prey sizes, this predation on smaller sizes may result in a potential loss of future, rather than current, fishing opportunities.

Résumé :

Abstract. First results of a coupled modeling and forecasting system for the pelagic fisheries are being presented. The system consists currently of three mathematically fundamentally different model subsystems: POLCOMS-ERSEM providing the physical-biogeochemical environment implemented in the domain of the North-West European shelf and the SPAM model which describes sandeel stocks in the North Sea. The third component, the SLAM model, connects POLCOMS-ERSEM and SPAM by computing the physical-biological interaction. Our major experience by the coupling model subsystems is that well-defined and

The paper aims at giving a brief review of the population structure, abundance and biomass dynamics of beaked redfish of the Irminger Sea obtained during the trawl acoustic surveys and analytical assessment. The adequacy of the current fisheries management measures for redfish in NEAFC is assessed. It was shown, that recent findings of the foreign genetic research apparently contradict to the relevant population structure for beaked redfish of the Irminger Sea applied in ICES, which specifies four stocks of the species.

Résumé :

Large-sized pelagic sharks and teleost fish are vulnerable to overexploitation by professional fisheries but little is known about the species caught by recreational fishing. This study presents for the first time in the Mediterranean an evaluation of the catch of pelagic sharks and teleost fish being caught by recreational fishermen by analyzing publicly available videos posted on social media. The analysis reveals that several vulnerable species, including the blue shark Prionace glauca, the shortfin mako Isurus oxyrinchus, the thresher shark Alopias vulpinus, the sixgill shark Hexanchus gri

Résumé :

Background: Ghana’s marine artisanal fisheries, particularly the small pelagic fisheries, are in a state of crisis. The decline in the number of small pelagic fish are attributable to overfishing, climate variability and unsustainable fishing methods. Similarly, in the wake of climate change, shellfishes (particularly oysters, scallops and mussels) are highly vulnerable. Methods: A total of 55 years’ worth of data from Ghana’s marine artisanal fisheries were studied in relation to climate indices. The primary objective was to develop a simple linear regression model for predicting shellfish ca

Abstract The purse seine is the dominant fishing gear operating at the Tumumpa Fishing Port with a vessel of >90%. The purse seines that have developed are large pelagic targets, with the main catch targets being skipjack, mackerel tuna, and tuna. Tuna, mackerel tuna and skipjack are important commodities for fisheries in Indonesia. This study aims to determine the characteristics of purse seine fishing gear and its catch in the Sulawesi Sea. Data collection was carried out for two years from 2019-2020 at Tumumpa Fishery Port. Indications for the use of fish resources are calculated by comp

Résumé :

Tuna fisheries have been identified as one of the major threats to populations of other marine vertebrates, including sea turtles, sharks, seabirds and marine mammals. The development of technical mitigation measures (MM) in fisheries is part of the code of conduct for responsible fisheries. An in-depth analysis of the available literature regarding bycatch mitigation in tuna fisheries with special reference to elasmobranchs was undertaken. Studies highlighting promising MMs were reviewed for four tuna fisheries (longline, purse seine, driftnets and gillnet, and rod and line – including recrea

Résumé :

Abstract Fisheries management is commonly based on the outputs of single-species stock assessment models. While such models are appropriate for tactical issues such as quota setting, they typically omit explicit trophic interactions between different parts of the ecosystem. To successfully manage multiple fisheries in the same ecosystem, we need to understand how fishing one species may indirectly affect other species. In this paper, we used a simulation model of the southern Benguela ecosystem, built in the Atlantis framework, to explore fisheries interaction effects. We first measured the im

Résumé :

The aim of this paper is to give a description of the Mediterranean fisheries, and its level of exploitation and to address the main questions dealing with its management. The Mediterranean is a semi-enclosed marine area with generally narrow continental shelves. The primary production of the Mediterranean is among the lowest in the world (26-50g C m-2 y-1). The Mediterranean fisheries can be broken down into three main categories: small scale fisheries, trawling and seining fisheries, which operated on demersal, small pelagic and large pelagic resources.

It is commonly acknowledged that body weight of fish is a key factor in determining market value of landed catch, thus influencing optimal harvest strategies. However, in management strategy evaluations and bioeconomic modelling, body size is often an overlooked economic parameter, and there are no systematic studies on the prevalence of size-dependent pricing.

To implement effective ocean governance, development of policies and management strategies needs to incorporate input from communities that will be impacted by the decisions.
