Ontogenetic and spatial variation in the trophic ecology of the shortfin mako shark (Isurus oxyrinchus) in temperate eastern Australia

Journal of Fish Biology, EarlyView.
Abstract The shortfin mako (Isurus oxyrinchus) is a fast‐swimming pelagic shark of global ecological and socioeconomic importance, yet it is relatively understudied in temperate eastern Australian waters. This study investigated the trophic ecology of mako sharks using stable isotope analysis (SIA) of nitrogen (δ15N), carbon (δ13C) and sulphur (δ34S ...

Discards in fisheries - a summary of three decades of research at IMARES and LEI [PDF]

, 2011
Discards and the possible ecological and economic effects of discarding are a hot topic in discussions about sustainable fisheries. The perception of the effects of discarding differs between parties and it is influenced by the ecosystem functioning and ...

Engaging small-scale fishers in a circular bioeconomy: valorization of Rhizostoma pulmo (Macri, 1778) jellyfish bycatch for sustainable collagen production

Frontiers in Marine Science
Jellyfish bycatch poses challenges for small-scale fisheries by increasing costs and generating underutilized biomass. Yet this same biomass could represent a valuable resource, as jellyfish are an emerging source of collagen with a wide range of ...

Mismatches between genetic and assessment units in commercial fish species: A systematic review in the North‐East Atlantic

Journal of Fish Biology, EarlyView.
Abstract While sustainable fisheries depend upon spatial and temporal identification at below the species level (i.e., stock units), the choice and identification of appropriate units remain challenging. Advances in DNA sequencing and improved computational power have generated extensive genetic and genomic data on the spatio‐temporal dynamics and ...

The National Marine Fisheries Service’s National Bycatch Strategy [PDF]

, 2004
The National Marine Fisheries Service (NMFS) launched its National Bycatch Strategy (NBS) in March 2003 in response to the continued fisheries management challenge posed by fisheries bycatch. NMFS has several strong mandates for fishand protected species

Revealing potential Atlantic salmon bycatch hotspots from pelagic fisheries landings across the Northeast Atlantic

Journal of Fish Biology, EarlyView.
Abstract Atlantic salmon (Salmo salar) marine survival has declined markedly over the past five decades, leading to concerns about future population viability. While many studies have explored the impacts of stressors such as climate change and predation, less is known about bycatch from pelagic fisheries targeting finfish species.

Southeast United States fisheries bycatch reduction research in shrimp trawl fisheries [PDF]

, 1997
Presented in the paper are the two devices that were developed by some states in the southeast United States to reduce fisheries bycatch in shrimp trawls. These were Turtle Excluder Device (TED) and Bycatch Reduction Device (BRD).

Competitive exclusion, not predation, likely drove the decline in native fish diversity following carnivorous fish introductions to Lake Titicaca in the mid‐20th century

Journal of Fish Biology, EarlyView.
Abstract Lake Titicaca is a continental centre for ichthyological biodiversity, with over 90% of native species being endemic. However, these species face significant threats from invasive species, particularly from invasive salmonids and invasive Argentine pejerrey.

The Bioeconomic Implications of A Bycatch Reduction Device as a Stock Conservation Management Measure [PDF]

The proposed regulation to reduce bycatch and discarding of finfish in the southeastern region is a gear modification that excludes finfish from shrimp trawls.

False killer whales and fisheries in Hawaiian waters: evidence from mouthline and dorsal fin injuries reveal ongoing and repeated interactions

Endangered Species Research
Monitoring bycatch in fisheries is essential for effective conservation and fisheries sustainability. False killer whales Pseudorca crassidens in Hawaiian waters are known to interact with both commercial and recreational fisheries, but limited observer ...
