Preliminary results from a bottom trawl survey of Lake Rudolf with additional notes on trials with a midwater frame trawl [PDF]
, 1975 This paper includes a short report on preliminary midwater hauls with a frame trawl. The object is (a) to study the relationship between the vertical distribution of pelagic fish and the scattering layer, and (b) to find out if certain species, which at

Worldwide Invasions of Centrarchidae: The Dark Side of the Sunfish Family
Fish and Fisheries, Volume 27, Issue 4, Page 781-812, July 2026.ABSTRACT Freshwater fish invasions are major drivers of global ecological change, disrupting native biodiversity and ecosystem functions. However, many invasive fish hold significant socioeconomic value, resulting in conflict over their management. Centrarchidae, which are globally distributed and are important for sportfishing and aquaculture, are now

Fish and Fisheries, Volume 27, Issue 4, Page 912-926, July 2026.ABSTRACT The consequences of mis‐managing vulnerable stocks (i.e., those with low productivity and high susceptibility to depletion) are high and potentially permanent. To support sustainable fisheries management, stock assessments can be improved by increasing the quantity and quality of fishery‐independent survey (i.e., survey) data.

Environmental Drivers of Jumbo Squid During Fishery Collapse in the Gulf of California (2019–2024)
Fisheries Oceanography, Volume 35, Issue 4, Page 477-491, July 2026.ABSTRACT The jumbo squid (Dosidicus gigas) is a cephalopod endemic to the eastern Pacific with significant ecological and economic importance. Its exploitation in the Gulf of California (GC) peaked in the 1990s, with catches exceeding 100,000 tons, but collapsed in 2009 and virtually disappeared by 2015, largely due to environmental changes and ...

Fisheries Oceanography, Volume 35, Issue 4, Page 565-579, July 2026.ABSTRACT Small pelagic fish and other forage species are patchily distributed over space and time, resulting in variable foraging conditions experienced by their predators. The high‐resolution data necessary to understand the spatiotemporal structure of forage communities are challenging to collect with expensive fishery‐independent surveys, meaning ...

EVALUATION OF MIDWATER TRAWL SELECTIVITY AND ITS INFLUENCE ON ACOUSTIC-BASED FISH POPULATION SURVEYS [PDF]
, 2013 Thesis (Ph.D.)--University of Washington, 2013Trawls are used extensively during fisheries abundance surveys to derive estimates of fish density and, in the case of acoustic-based surveys, to identify acoustically sampled fish populations.

FEATURES OF FISH BEHAVIOR IN THE ACTION ZONE OF MIDWATER TRAWL
, 2017 Researches in the field of behavior and distribution of fish at different stages of fishing were conducted using midwater trawls in order to increase fishing efficiency, subject to the fact that, besides fish behavior, parameters of midwater trawls and ...
