The use of a square mesh codend and sorting grids to reduce catches of young fish and improve sustainability in a multispecies bottom trawl fishery in the MediterraneanEl uso de copo de malla cuadrada y rejillas separadas para reducir las capturas de pece

Scientia Marina, 2006
In order to improve the capacity of bottom trawl fishing gears to reduce catches of young fish and discards in a highly exploited demersal trawl fisheries in the Mediterranean, the size-selection performance of a 36-mm square-mesh codend and two sorting ...

First Report of ‘Soft Flesh’ Induced by the Parasite Kudoa thyrsites (Myxosporea) in Commercial Codfish From Norway

Journal of Fish Diseases, Volume 48, Issue 4, April 2025.
ABSTRACT Kudoa thyrsites is a myxosporean parasite that infects the skeletal muscle of various teleost fish species globally. Severe infections lead to ‘soft flesh’ in fish fillets, resulting in food spoilage and subsequent discard. While K. thyrsites has previously been identified in migratory Atlantic mackerel in the northern Northeast Atlantic Ocean,

The Greenland–Scotland Ridge in a Changing Ocean: Time to Act?

Marine Ecology, EarlyView.
ABSTRACT The Greenland–Scotland Ridge is a submarine mountain that rises up to 500 m below the sea surface and extends from the east coast of Greenland to the continental shelf of Iceland and across the Faroe Islands to Scotland. The ridge not only separates deeper ocean basins on either side, that is, the North Atlantic and Arctic oceans, but also ...

Scope for Efficient Multinational Exploitation of North-East Atlantic Mackerel [PDF]

Marine Resource Economics, 2003
The three major harvesters of North-East Atlantic mackerel are modelled as exercising alternative coalitional strategies. Incentives for coalition formation are analysed by finding the maximum rents that harvesters can obtain under all possible coalition arrangements.

Fish Sperm Subpopulations Detection, Separation, and Application: Current State and Trends

Reviews in Aquaculture, Volume 18, Issue 4, September 2026.
Modern advances in sperm biology highlight the necessity of recognising intra‐ejaculate heterogeneity as a central concept for advancing both the fundamental understanding of fertilisation processes and the development of artificial reproduction techniques in fishes. ABSTRACT Sperm subpopulations represent a fundamental manifestation of intra‐ejaculate

Atlantic Mackerel (Scomber scombrus) Population and Habitat Trends in the Northwest Atlantic

, 2020
Atlantic mackerel (Scomber scombrus) has long been a significant marine resource in the northwest Atlantic, supporting commercial and recreational fisheries over two centuries. As a small pelagic fish feeding on planktonic organisms, mackerel serve a critical role in the marine food web as prey for higher trophic level species, including large ...

Fecundity of the Atlantic Mackerel (Scomber scombrus) in the Northwest Atlantic in 1987

Journal of Northwest Atlantic Fishery Science, 1992
Fecundity estimates of Atlantic mackerel (Scomber scombrus) were derived from fish collected in 1987 off the coast of USA and Canada from two spawning contingents in the Northwest Atlantic. Estimates for females of 310 to 446 mm fork length in USA waters ranged from 155 900 to 1 643600 eggs.

Tuning the tools: Validating empirical and modelled correction factors for diet estimation in pelagic teleosts

Methods in Ecology and Evolution, Volume 17, Issue 7, Page 2218-2233, July 2026.
Abstract As quantitative diet estimates from biochemical markers grow in popularity, the necessity for robust species‐ and tissue‐specific correction factors, including trophic discrimination factors (TDFs) for stable isotopes and calibration coefficients (CCs) for fatty acids, becomes increasingly urgent.

Advancing Ecological Understanding and Sustainable Management of Small Pelagic Fish

Fish and Fisheries, Volume 27, Issue 4, Page 850-864, July 2026.
ABSTRACT Small pelagic fish (SPF) are critical to the trophodynamic structure and function of marine systems and support some of the most valuable and socially important fisheries worldwide. Their “boom and bust” population dynamics, shifts in distribution, and importance as forage resources for other fish stocks place unique challenges to assessing ...

Parasites of Kunene horse mackerel Trachurus trecae (Smith-Vaniz, 1986) with a comparison of parasites of Cape horse mackerel T. capensis (Castelnau, 1861) in the northern Benguela

, 2013
Two species of horse mackerel (Trachurus trecae and Trachurus capensis) reside in the northern Benguela ecosystem. Both are important economic commodities for the Angolan and Namibian fisheries and therefore need to be managed appropriately. Although the
