Dynamic Simulation of Pelagic Longline Retrieval
Journal of Ocean University of China, 2019To improve fishing gear efficiency, it is important to understand the interactions among sea current, fishing vessel, line hauler, and catches during pelagic longline gear retrieval. In this study, fishing gear configuration parameters, operational parameters, and 3D ocean current data were collected from Indian Ocean.

The loss of seed mussels in longline aquaculture
Reviews in Aquaculture, 2021AbstractThe substantial loss of seed mussels during the early stages of longline aquaculture—often exceeding 95%—is a major issue that erodes the security and profitability of production while limiting the sustainable expansion of this industry in many parts of the world.

The dynamic simulation of the pelagic longline deployment
Fisheries Research, 2015Abstract It is important to understand the deployment of pelagic longline gear for reducing non-target species interactions, and increasing fishing efficiency. In the present study hook depth data, simultaneous settlement data, and three-dimensional (3D) ocean current data were collected aboard the fishing vessel “Huananyu 716” while operating near ...

The impact of longlines on the economy as a whole
2019Человек – важная часть экономики. Для эффективной работы системы очень важно психологическое состояние человека. Ежегодно во многих странах, в том числе и в России, отмечается рост числа одиноких людей. По статистике разводов Россия занимает четвертое место после Мальдив, Беларуси и Бельгии.

Estimating Abundance from Longline Catches
Journal of the Fisheries Research Board of Canada, 1960The various factors that enter into the catch of fish by a baited longline are combined into equations that permit using the information afforded by the catches to compute linear estimates of abundance, providing that all rates can be estimated reasonably accurately, and assuming they are linear.

Studies on the Depth of Longline Hook
1985The tuna fishing experiments were carried out in the southern region of the Hawaiian Islands in May 1985. Some informations were obtained on the relation between the calculated catenary value and the actual survey value of the depths of hooks of tuna long line and were discussed in comparison with the results of study in 1984.

Advice on threshold levels for longline fishing
2022ICES advises the use of a threshold of 10 VME indicators caught per 1000 hook segment or per 1200 m section of long line, whichever is the shorter, to indicate the presence of a VME.

Evidence of hook competition in longline surveys
2008Catch rates from surveys are used as indices of abundance for many fish species. Relative abundance estimates from surveys with longline gear do not usually account for possible effects of gear saturation, which potentially creates competition among fish for baited hooks and misrepresentations of abundance trends. We examined correlations between catch
