Summary: This study sequenced and assembled the genome of the economically important Southern bluefin tuna. The researchers found that this fast-swimming fish has more hemoglobin genes and a mutated beta-hemoglobin compared to slower-moving fishes. These findings suggest that the high copy numbers of hemoglobin genes and the adjusted function of beta-hemoglobin may support the fast-swimming activity of tunas.

Summary: This study investigated the quality characteristics of southern bluefin tuna during refrigerated storage at 4 degrees C, finding that lipid and protein oxidation aggravated with storage time, leading to browning. The model constructed using partial least squares showed that thiobarbituric acid reactive substance content was significantly correlated with color stability.

Summary: The study found that Southern Bluefin Tuna showed the same pattern in changes in the surface area of MMCs, but blood fluke infection varied significantly between different cohorts and individual fish within the same cohort. Cardicola forsteri had a higher prevalence than Cardicola orientalis. This research contributes to our understanding of blood fluke infections in Southern Bluefin Tuna and their interactions with MMCs.

Summary: This study standardized the CPUE of southern bluefin tuna from the Korean tuna longline fishery using generalized linear models. The study found that the standardized CPUE decreased until the mid-2000s and has been increasing since then. The targeting patterns of Korean tuna longline vessels vary spatially, seasonally, and over the long term.

Summary: This study examines the foraging ecology of Pacific bluefin tuna in the California Current System. They found that the tuna's diet and foraging behavior varied over time, depending on the availability of prey. The study also highlights the importance of understanding the foraging ecology of this species for predicting its responses to changes in resource availability and its impact on fisheries.

Summary: Studies have found that southern bluefin tuna has high genetic diversity and can be divided into two clades, A and B, distributed in the Indian Ocean and the Atlantic Ocean. A historic differentiation event may have occurred in the past, but recent connectivity between the two oceans is still possible in southern bluefin tuna populations.

Summary: This study investigated the reproductive traits of Pacific bluefin tuna in the Nansei Islands and waters off southwestern Honshu Island. The results showed that the distribution of spawning fish was influenced by sea surface temperatures, with a peak in late June. Mature female fish were widely distributed in the study area. The spawning fraction increased over time, and batch fecundity was positively affected by fork length and days since the start of the season.

Summary: This study investigated the biochemical characteristics of key digestive enzymes in artificially produced Pacific bluefin tuna juveniles, revealing that long-term feeding of a commercial diet could significantly increase the storage/synthesis levels of digestive enzymes, while short-term feeding of the same diet resulted in faster gastric emptying and increased storage/synthesis levels of digestive enzymes.

Summary: Tuna's rigid body should limit their turning performance, but they overcome this limitation by increasing the flexibility of their tail and utilizing specific turning behaviors.

Summary: The study focused on the pre-flexion stages of Atlantic bluefin tuna larvae collected in the Gulf of Mexico and the Mediterranean Sea. It examined the growth, otolith biometry, and stable isotopes of the larvae. The results showed that the Gulf of Mexico larvae had faster growth, larger otoliths, wider daily increments, and lower δ15N values compared to the Mediterranean. In addition, the study found a direct relationship between growth potential, development, and maternal transmission of isotopic signatures.

Summary: In this study, we investigated the succession process of intestinal bacteria during seed production of Pacific bluefin tuna. The results showed a clear succession of intestinal bacteria during the seed production process. Proper management of the seed production process is crucial for the aquaculture of healthy fish.

Summary: The study examined the potential of otolith microchemistry in understanding the spatial dynamics of skipjack tuna, a valuable commercial species in the Indian Ocean. Differences in otolith chemical signatures were observed among individuals from different nursery areas, but there was significant overlap in the signatures of the three nurseries. Cohort effects on otolith trace element signatures were detected, highlighting the importance of understanding seasonal variations in oceanographic conditions for species with multiple reproductive peaks throughout the year.

Summary: Yellowfin tuna are highly exploited in the Indian Ocean, with their stock structure not well understood. This study collected otoliths from young-of-the-year yellowfin tuna in major nursery areas to explore the spatial distribution of trace elements and stable isotopes, revealing significant regional variations in the chemical signatures of the otoliths. The study demonstrates that these baseline chemical signatures can be used as natural tags to determine nursery origins in the Indian Ocean.

Summary: This study investigates the differences in growth parameters of swordfish and assesses the most appropriate hard part for age estimation. The results reveal methodological differences in estimating age using fin rays in the Pacific, and a clear bias in age estimates between fin rays and otoliths. The study recommends standardizing hard part reading methods and investigating otolith-based age estimation for billfish stocks and other fish species.

Summary: The study utilized otolith delta O-18 values of young-of-the-year yellowfin tuna from various nursery areas in the equatorial Indian Ocean to establish a reference isotopic signature for predicting the origin of sub-adult and adult individuals. The analysis found that sub-adult tuna from Reunion Island showed similarity to the West nursery signature, while those from Pakistan did not match any of the known nurseries sampled, indicating an additional nursery source.
