Listening to tuna: Acoustic characterization of captive juvenile yellowfin tuna (Thunnus albacares). [PDF]

J Fish Biol
Abstract The effectiveness of passive acoustic monitoring (PAM) for studying marine biodiversity highly relies on comprehensive libraries of species‐specific sounds. While sound production is well‐documented in reef and freshwater fishes, the acoustic behaviour of ecologically and economically vital pelagic species like tunas still remains largely ...

Sample size requirements for genetic studies on yellowfin tuna. [PDF]

PLoS One, 2021
In population genetics, the amount of information for an analytical task is governed by the number of individuals sampled and the amount of genetic information measured on each of those individuals. In this work, we assessed the numbers of individual yellowfin tuna (Thunnus albacares) and genetic markers required for ocean-basin scale inferences.

Comparative analysis of three bait types in deep-set pelagic longline gear in the Equatorial Atlantic Ocean

Boletim do Instituto de Pesca, 2022
The choice of bait is one of the fisheries tactics used to increase selectivity for particular target species. The performance of three bait types (mackerel, sardine, squid) was evaluated with a commercial vessel operating in the Equatorial Atlantic ...
