Artificial intelligence for fish behavior recognition may unlock fishing gear selectivity

Frontiers in Marine Science, 2023
Through the advancement of observation systems, our vision has far extended its reach into the world of fishes, and how they interact with fishing gears—breaking through physical boundaries and visually adapting to challenging conditions in marine ...

Fisheries management based on gear selectivity of a tropical reservoir, Lake Nasser, Egypt

Egyptian Journal of Aquatic Research, 2020
Lake Nasser, a large man-made tropical reservoir, is located in the southern part of Egypt. The lakes’ fisheries have undergone a steady decrease during the last 10 years obscuring its potential for sustainability. Fisheries assessment study based on the

Effect of the Nordmøre grid bar spacing on size selectivity, catch efficiency and bycatch of the Barents Sea Northern shrimp fishery.

PLoS ONE, 2022
The introduction of the Nordmøre grid in shrimp trawls has reduced the bycatch of non-target species. In the Norwegian Northern shrimp (Pandalus borealis) fishery, the mandatory selective gear consists of a Nordmøre grid with 19 mm bar spacing combined ...

Introduction of hook size as a tool for management measures of harvest control rules to improve grouper stock in Indonesia

Fisheries and Aquatic Sciences, 2023
Harvest control rules have been recently developed for some fisheries in Indonesia, including grouper fisheries, and are expected to reverse the trend of declining stocks. One of the proposed options of the harvest control rules is to implement the catch

Design and Operation of “Siklob”, a Mechanised Falling Gear Operated in Northern Iloilo, Philippines

Asian Fisheries Science, 2021
Fisheries in the Philippines is multispecies, and this is seen with the wide variety of fishing gears used in major and minor fishing grounds in the country. These gears constantly face modification and development to improve catch quality, quantity, and

Trap Happiness and Catch Bias in Sea Lamprey Traps

Fishes, 2019
Sampling fish by trapping can lead to biased conclusions about a population. We used catch data to assess differences between two types of traps for adult sea lamprey (Petromyzon marinus), submerged-funnel traps and studded-tile traps, which are angled ...

Comparing handline and trolling fishing methods in the recreational pelagic fishery in the Gulf of Oman

Scientia Marina, 2019
The choice of fishing gear and catching strategy should be taken into consideration in the management of fish stocks. Here, paired fishing trials in a pelagic recreational fishery compared the catch composition, catch rate and size selectivity between ...

Compensatory recruitment, dynamic habitat, and selective gear present challenges to large‐scale invasive species control

Ecosphere, 2020
Control of long‐established invasive species to aid threatened native species presents major logistic and economic challenges. Invasive common carp (Cyprinus carpio) recently accounted for over 90% of the fish biomass in Utah Lake (Utah, USA), driving ...

Assessment of a small-scale fishery: Lane Snapper (Lutjanus synagris) using a length metric method.

PLoS ONE, 2021
Small-scale fisheries are hard to assess because of the limited availability of data. Therefore, a method requiring easy-to-obtain catch-data is important for the assessment and management of small-scale fisheries.
