Behavior of prey links midwater and demersal piscivorous reef fishes

Neotropical Ichthyology
Pelagic and demersal guilds of piscivorous fishes are linked by a variety of biological and physical processes that mediate interactions with common prey species.

Fish landings and Oman shelf area

Journal of Agricultural and Marine Sciences, 2016
Data from five field surveys carried out along the shelf in the 20-250m depth range and historical data on artisanal fishery were analyzed. A positive linear relationship between the demersal fish biomass and the shelf area was pronounced for a certain ...

DNA barcoding and misidentification of some marine fish species in Nigerian industrial trawl fishery

Scientific African, 2023
Identification of marine fishes across their geographical distribution is based primarily on morphological features. The ability of marine fishes to adapt to environmental changes sometimes leads to morphological differences that might give rise to wrong

Using hydrodynamics to modify fishing performance of a demersal fishing gear

Fisheries Research, 2023
This study demonstrates how hydrodynamics can be used to influence the fishing performance of towed demersal fishing gears. Sea trials are performed in the sea star fishery to show how modifications to the gear design alter the hydrodynamics of the turbulent wake and consequently affect the catching performance of trawl gears.

Supplements to the generalized quantitative assessments of benthic macrofauna in the Far Eastern Seas and adjacent waters of the Pacific Ocean. Report 1. Regional features of distribution for biomass of fish

Известия ТИНРО, 2016
Long-term information on mean annual biomass of the main taxa of bottom and demersal fishes on the shelf and upper continental slope (down to 2025 m) in the Far Eastern Seas and adjacent Pacific waters is summarized.

Testing the Improvement of Coral Reef Associated Fish Distribution Models Based on Multibeam Bathymetry by Adding Seafloor Backscatter Data

Frontiers in Marine Science, 2021
Demersal fishes constitute an essential component of the continental shelf ecosystem, and a significant element of fisheries catch around the world. However, collecting distribution and abundance data of demersal fish, necessary for their conservation ...

Latitudinal effect on the structure of snake–prey interaction networks is mediated by snake species richness

Ecography, EarlyView.
Despite the growing number of studies on trophic networks in recent decades, there are still important gaps in our understanding of how these networks are structured across broad environmental gradients. These gaps are even greater in some groups of terrestrial vertebrates, such as snakes, requiring a cohesive synthesis of their broader trophic ...

Community‐level egg and larval trait interactions with the Amazon River plume determine its role as a dispersal barrier

Ecography, EarlyView.
The Amazon River plume (ARP) functions as a dynamic and porous biogeographic barrier whose permeability to larval dispersal depends on the interplay between species' biological traits and oceanographic processes. Using biophysical modeling combined with a dual analytical framework, namely a multivariate regression tree (MRT) and a generalized additive ...

Demersal Fish Assemblages in NE Atlantic Seagrass and Kelp

Diversity, 2020
Global fisheries are in decline, calling for urgent evidence-based action. One such action is the identification and protection of fishery-associated habitats such as seagrass meadows and kelp forests, both of which have suffered long-term loss and ...
