Pilot research on species composition of Korean purse seine catch at cannery
A preliminary study on species composition of a Korean purse seine catch landed at cannery was conducted in April 2011. In the cannery, all tuna catch are sliding through a sorting grid panel that filters and drops fish in the buckets by size class (above 9 kg, 3.4-9 kg, 1.8-3.4 kg, 1.4-1.8 kg and below 1.4 kg).

متن کاملModelling the Spatial Behaviour of a Tropical Tuna Purse Seine Fleet
Industrial tuna fisheries operate in the Indian, Atlantic and Pacific Oceans, but concerns over sustainability and environmental impacts of these fisheries have resulted in increased scrutiny of how they are managed. An important but often overlooked factor in the success or failure of tuna fisheries management is the behaviour of fishers and fishing fleets. Uncertainty in how a fishing fleet w...
متن کاملHydrodynamic characteristics of knotted and knotless purse seine netting panels as determined in a flume tank
Nylon (PA) netting is widely used in purse seines and other fishing gears due to its high strength and good sinking performance. However, hydrodynamic properties of nylon netting of different characteristics are poorly understood. This study investigated hydrodynamic characteristics of nylon netting of different knot types and solidity ratios under different attack angles and flow velocities. I...
متن کاملPost-release survival of juvenile silky sharks captured in a tropical tuna purse seine fishery
Juvenile silky sharks Carcharhinus falciformis comprise the largest component of the incidental elasmobranch catch taken in tropical tuna purse seine fisheries. During a chartered cruise on board a tuna purse seine vessel conducting typical fishing operations we investigated the post-release survival and rates of interaction with fishing gear of incidentally captured silky sharks using a combin...
