Post-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...

Fishing Capacity Reduction Program for the Southeast Alaska Purse Seine Salmon Fishery

NMFS establishes regulations to implement a fishing capacity reduction (buyback) program and an industry fee system to repay a $23,476,500 loan for the Southeast Alaska Purse Seine Salmon Fishery (Reduction Fishery). The fee system involves future landings of the Reduction Fishery. This action’s intent is to permanently reduce the most fishing capacity at the least cost and establish the fee sy...

Hydrodynamic 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...

Multi-species Assessment of Tunas Caught in the Tropical Atlantic Purse Seine Fishery: Sensitivity of Production Models to Biases in Reported Catches

In this document, different scenarios of uncertainties in a multispecies fishery are presented. Uncertainties have been considered in the estimation of the species composition of the tropical tuna catch as well as in the total catch. Although three species (yellofin, skipjack and bigeye) are involved in the tropical tuna fishery, only uncertainties in the bigeye vs skipjack have been taken into...
