Abstract The interactive effects of turbulence and suspended particulate matter (SPM) on copepod feeding and egestion remain poorly understood. We experimentally examined how turbulence (0, 10−3, and 100 cm2 s−3) and SPM (0 and 150 mg L−1; Diatomaceous Earth), alone and combined, affect ingestion, fecal pellet production, gut passage time, assimilation

ABSTRACT Central to ecosystem‐based fisheries management is ensuring the sustainability of bycatch and byproduct species. However, the sustainability of these species is difficult to assess as the lack of information limits the use of traditional stock assessment methods.

Advancing Ecological Understanding and Sustainable Management of Small Pelagic Fish
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 ...

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.

ABSTRACT Rapid changes in marine ecosystems highlight the need to account for time‐varying productivity in stock assessments used to support fisheries management. Common approaches incorporate annual variation or regressing processes such as recruitment, natural mortality, or growth on environmental variables.

ABSTRACT Technological innovations for predicting fish age represent a paradigm shift from conventional age estimation methods used in fisheries science. Recently developed secondary methods rely on models trained on conventional age estimates, derived from subjective interpretation of growth patterns and a biological property of the fish to predict ...

Challenges and Opportunities for Strengthening Bottom‐Tow Fisheries Sustainability
ABSTRACT Bottom‐tow gear fisheries (trawls and dredges) produce ~24 million mt of harvest annually, representing a globally important animal‐sourced food system. While many are currently sustainably managed, growing concern over the potential for ecosystem impacts from bottom‐tow gears has increased pressure to improve these fisheries.

Numerical modeling of bottom trawling-induced sediment transport and accumulation in La Fonera submarine canyon, northwestern Mediterranean Sea [PDF]
Bottom trawling leads to recurrent sediment resuspension events over fishing grounds. Recent studies have shown how bottom trawling can drive seascape reshaping at large spatial scales and enhance sediment transport in submarine canyons, which ...

The recent markedly reduced recruitment success (recruitment per spawner stock biomass) of Northeast Arctic cod (Gadus morhua, Gadidae) is seemingly largely attributed to the joint negative effect of increased temperature and cannibalism but also predation on the postlarvae by Northeast Atlantic mackerel (Scomber scombrus, Scombridae).
