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

Study on Dynamic Characteristics and Fracture Failure of Rigid Truss Trawl System During Towing Process

Journal of Marine Science and Engineering
Deep-sea fisheries depend on various fishing methods, including trawling, purse seining, and longline fishing, among others. Studying the dynamic characteristics of trawling operations is essential for the trawl mechanism.

VERDA: A Multisampler Tool for Mesopelagic Nets

Journal of Marine Science and Engineering, 2023
Different types and systems to discriminate plankton samples at different strata in the water column have been developed in recent decades. For sampling at sufficient depth, opening and closing zooplankton multinets are ideal because there is no ...

Contrasting life‐history strategies of three sympatric icefish species in the northern Scotia Sea

Journal of Fish Biology, EarlyView.
Abstract Comprehending a species' life‐history strategies is crucial to inform effective conservation efforts. Commercial fishing impacts icefish (family: Channichthyidae) in the Scotia Sea, but detailed information on species‐specific life histories remains largely unknown.

The state of knowledge on four families of Syngnathoidei fishes (Teleostei: Syngnathiformes): Aulostomidae, Centriscidae, Fistulariidae and Solenostomidae

Journal of Fish Biology, EarlyView.
Abstract Knowledge on the ecology and life‐history traits of coastal marine species is vital to inform their conservation and management, especially as their coastal habitats come under increasing threats. However, such data have never been collated for four of the five families in the suborder Syngnathoidei—the close relatives of the better‐studied ...

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

The Meso- and Bathypelagic Fishes in a Large Submarine Canyon: Assemblage Structure of the Principal Species in the Gully Marine Protected Area

Frontiers in Marine Science, 2020
Midwater trawl surveys were conducted during 2007–10 at meso- and bathypelagic depths in and near The Gully, a large submarine canyon off Nova Scotia that is also a Marine Protected Area.

Exploration of the “larval pool”: development and ground-truthing of a larval transport model off leeward Hawai‘i [PDF]

PeerJ, 2016
Most adult reef fish show site fidelity thus dispersal is limited to the mobile larval stage of the fish, and effective management of such species requires an understanding of the patterns of larval dispersal.

Using Stock Vulnerability to Evaluate Fishery‐Independent Survey Coverage and Inform Sampling Priorities

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.
