High Coral Bycatch in Bottom-Set Gillnet Coastal Fisheries Reveals Rich Coral Habitats in Southern Portugal

Frontiers in Marine Science, 2020
Bottom-contact fisheries are unquestionably one of the main threats to the ecological integrity and functioning of deep-sea and circalittoral ecosystems, notably cold-water corals (CWC) and coral gardens.

Hooking efficiencies of SMART drumlines and their possible deployment rates vs gillnets for bather protection

Frontiers in Marine Science
IntroductionFor 87 years, gillnets have been deployed off up to 51 beaches in New South Wales, Australia, to reduce bites on humans by white (Carcharodon carcharias), bull (Carcharhinus leucas), and tiger (Galeocerdo cuvier) sharks. Recently, to minimise

Bycatch in gillnet fisheries threatens Critically Endangered small cetaceans and other aquatic megafauna

, 2019
The conservation status of small cetaceans has significantly worsened since the 1980s, when the baiji was the only species of small cetacean listed as Endangered by IUCN.

Comparative study on the catch efficiency and size selection of entangling nets in Lake Kainji, Nigeria [PDF]

, 2005
The relative catch performance and selectively of gillnets and trammel nets were investigated in 12 sampling stations in Lake Kainji, Nigeria. 3 types of nets with dimensions 50mx3m were constructed using 76mm and 178mm meshsizes for two gillnets, 76mm ...

KONSTRUKSI ALAT TANGKAP GILLNET DI WADUK JATIGEDE

ALBACORE Jurnal Penelitian Perikanan Laut, 2023
Waduk Jatigede merupakan waduk yang dipergunakan sebagai sarana penangkapan ikan. Usia yang terbilang muda berpengaruh bahwa informasi tentang penangkapan di Waduk Jatigede masih sulit ditemukan. Belum adanya informasi terkait pelaku kegiatan penangkapan ikan di Waduk Jatigede oleh pemerintah menyebabkan pengelolaan yang belum optimal.

Postmortem findings in Magellanic penguins (Spheniscus magellanicus) caught in a drift gillnet

BMC Veterinary Research, 2020
Penguin interaction with gillnets has been extensively reported in the Atlantic and Pacific Oceans, and is considered a major conservation threat. Among penguin species, Magellanic penguins (Spheniscus magellanicus) are currently considered of great ...

Sensory Biology of the Franciscana (Pontoporia blainville, Pontoporiidae, Cetartiodactyla): Ontogenetic Modifications of Vibrissae and Vibrissal Crypts

Integrative Zoology, EarlyView.
The transition of cetaceans from a terrestrial to an aquatic environment involved a crucial sensory adaptation to environments with limited visibility. Vibrissae, important mechanoreceptors, undergo an ontogenetic transformation in odontocetes. This research describes the histomorphology of vibrissae and crypts at different developmental stages ...

Harnessing Solar Energy to Reduce Sea Turtle Bycatch

Conservation Letters
Over the past decade, illuminating gillnets with LED lights or chemical lightsticks has emerged as a promising solution to reduce sea turtle bycatch while maintaining target fish catch across multiple ocean basins. However, LED lights require replaceable

Gillnet selectivity to roach, Rutilus rutilus, from the Szczecin Lagoon, Poland [PDF]

Acta Ichthyologica et Piscatoria, 2007
Background. Roach, Rutilus rutilus, comprise a large proportion of the total catch in the Szczecin Lagoon, and are caught mainly as bycatch in gillnets targeting perch, Perca fluviatilis. The minimum landing length for roach and perch is 17 cm TL and the
