Predicting Historical Populations and Evaluating Shifting Baselines of Traditionally Exploited Fisheries

open access: yesFish and Fisheries, EarlyView.
ABSTRACT Development of data‐intensive stock assessment and ecosystem‐based models has improved our understanding of shifting species abundance in response to fishing, ocean ecology, and species interactions. Along with this analytical progress is evidence that many stocks lack data required for complex models, resulting in data‐limited options for ...

Global Analysis of Shallow Underwater Fish Observation Research: 70 Years of Progress, Persistent Geographic Biases and a Path Forward

open access: yesFish and Fisheries, EarlyView.
ABSTRACT Marine ecosystems are increasingly threatened by overfishing, pollution, coastal development and climate change, underscoring the need for long‐term, representative information on key fish populations and habitats to inform management and policy.

The repulsive and feeding-deterrent effects of electropositive metals on juvenile sandbar sharks (Carcharhinus plumbeus) [PDF]

open access: yes, 2009
Reducing shark bycatch and depredation (i.e., damage caused by sharks to gear, bait, and desired fish species) in pelagic longline fisheries targeting tunas and swordfish is a priority. Electropositive metals (i.e., a mixture of the lanthanide elements

High Contents of Trimethylamine Oxide Correlating With Depth in Deep-Sea Teleost Fishes, Skates, and Decapod Crustaceans

open access: yesThe Biological Bulletin, 1999
In muscles of shallow-living marine animals, the osmolyte trimethylamine N-oxide (TMAO) is reportedly found (in millimoles of TMAO per kilogram of tissue wet weight) at 30-90 in shrimp, 5-50 in crabs, 61-181 in skates, and 10-70 in most teleost fish.

Visual Modelling to Predict Behavioural Responses of Catsharks, Skates, and Plaice to Artificial Light for Use in Bycatch Reduction

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Light can be used to deter bycatch from fishing nets, but few studies have aimed to quantify how species view and respond to light. Here, we used visual models to predict how target (plaice Pleuronectes platessa) and bycatch (small‐spotted catshark Scyliorhinus canicular and undersized skates, Raja spp) species, captured in mixed demersal ...

Study of rheological properties of gels based on Thorny Skate cartilage broth (<i>Raja radiata</i>) in the technology of natural fish culinary products -aspic fish, in jelly, fish jellies and potions

open access: yesVestnik MGTU, 2020
The paper deals with methodological approaches to study the rheological properties of gelatin gels based on the thorny skate cartilage broth ( Raja radiate ), which is an aqueous extract of chondroitin sulfate, depending on the manufacturing technology.

Evaluating and Advancing the Use of Shore‐Based Observers for Scientific Sampling and Catch Verification in High‐Volume Fisheries

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Shore‐based observers are increasingly being used in place of at‐sea observers to monitor and sample commercial fisheries catch. However, few evaluations assess whether these programs meet their stated goals or how to optimize them, and industry data are rarely tested for accuracy despite serving as the foundation for catch accounting. Using a

High Cost and Low Trust: Insights From Qualitative Commercial Fishing Cost Data in the Northeast United States

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT In fisheries management, socioeconomic data, specifically qualitative data analysis, is often underutilized. This study qualitatively analyzed a primary federal data collection effort in the Northeast United States, The Greater Atlantic Region Commercial Fishing Business Cost Survey.

Giants in the cold: Morphological evidence for vascular heat retention in the viscera but not the skeletal muscle of the basking shark (Cetorhinus maximus)

open access: yesJournal of Fish Biology, EarlyView.
Abstract Fewer than 50 of the over 30,000 extant species of fishes have developed anatomical specializations facilitating endothermy in specific body regions. The plankton‐feeding basking shark (Cetorhinus maximus), traditionally classified as an ectotherm, was recently shown to have regionally endothermic traits such as centralized red muscle (RM ...

Metavirome survey of eight ray-finned fishes: Domination of giant viral members from pandoravirus and megaviricetes [PDF]

open access: yesJournal of Clinical and Basic Research
Background: Fish are an essential source of food worldwide. Most microbial diversity in marine ecosystems remains uncharacterized, with viruses accounting for most of the remaining diversity.
