Tagging Atlantic bluefin tuna from a Mediterranean spawning ground using a purse seiner
Fisheries Research, 2020 Atlantic bluefin tuna, Thunnus thynnus, is as an emblematic and commercially valuable large pelagic species. In the past ten years, the purse seine fishery in the Mediterranean represents more than 50 % of the catch.

Fundamental Studies on the Fishing Efficiency of Purse Seine
, 1986 Studies on the efficiency of purse seines were carried out in a water circulating experimental tank in a static water condition using five simplified seine models of different hang-in ratios. The results indicate that the seine with hang-in ratio of 34% sank the fastest and seines with 25% and 30% of hang-in ratios had sinking speeds nearly equal to ...

Estimating purse seine volume during capture: implications for fish densities and survival of released unwanted catches [PDF]
ICES Journal of Marine Science, 2019 High fish densities negatively impact catch welfare and the survival of unwanted catches released from purse seines. To avoid overcrowding fish before being released, regulations have been implemented in the Northeast Atlantic mackerel and herring ...

This chapter takes as its starting point Michel Callon’s famous paper, ‘Some elements of a sociology of translation: domestication of the scallops and fisherman of St Brieuc Bay’. After first introducing that paper and its core theoretical claims, the following sections attempt a re-reading of the famous ‘Tuna/Dolphin’ controversy, with a particular ...

The simulation of the geometry of a tuna purse seine under current and drift of purse seiner
Ocean Engineering, 2009It was necessary to obtain a more practical interactive precise model of the three-dimensional (3-D) geometry during purse seine operations considering movements of fishing vessel and details of the sea condition. The changes in the shape of a purse seine from shooting to pursing during pelagic skipjack fishing was recorded in the Southwest Pacific ...

A stochastic model for purse seining in a two-species fishery
Journal of Theoretical Biology, 1969Abstract Purse seine fishing in a two-species fishery is viewed as a semi-Markov process. Activities of a vessel during a fishing day are assigned to five states: searching, successfully setting on either species, and unsuccessfully setting on either species. Searching for fish schools is assumed to be a Poisson process.
