Abstract Skipjack (Katsuwonus pelamis), yellowfin (Thunnus albacares) and bigeye
(Thunnus obesus) tuna are the target species of tropical tuna fisheries in the Indian Ocean …

Changing environmental temperatures impact the physiological performance of fishes, and
consequently their distributions. A mechanistic understanding of the linkages between …

Tracking the movement of migratory fish is of great importance for efficient conservation,
although this has been technically difficult to achieve in small fish to which artificial tags …

Natural chemical markers (stable isotopes and trace elements) in otoliths of bigeye tuna
(Thunnus obesus) and yellowfin tuna (T. albacares) were used to investigate their origin and …

We evaluated the use of the stable oxygen isotope (δ 18 O) in the otolith as a proxy for the
temperature history of Japanese sardine Sardinops melanostictus individuals. Japanese …

Identifying the source of seafood is critical for combatting seafood fraud, but current tools are
predominantly developed and applied on a species‐specific basis. This study investigates …

Oxygen isotope ratios of the core region of otoliths were examined in Anguilla japonica
glass eels collected from two rivers in Japan to verify the possible temperature and depth …

Metabolic rate underpins our understanding of how species survive, reproduce and interact
with their environment, but can be difficult to measure in wild fish. Stable carbon isotopes …

This study aimed to reconstruct temperatures experienced during the larval period by adult
Pacific bluefin tuna Thunnus orientalis using high-resolution otolith stable oxygen isotope (δ …

Atlantic bluefin tuna (Thunnus thynnus) from the two main spawning populations in the
Mediterranean and Gulf of Mexico occur together in the western, central and eastern …
