Publisher Summary

This chapter elaborates the different aspects of the reproductive biology of tunas. Tunas are predominantly dioecious and there is no sexual dimorphism in their external morphological characters. Tunas are oviparous, have asynchronous oocyte development, and are considered to be multiple or batch spawners, shedding their gametes directly into the sea, where egg fertilization occurs. The reproductive characteristics of a stock, along with those of growth and mortality, are among the most important factors in determining the regenerative ability of a population. Most studies of gonadal development in tunas, intended to describe maturation and spawning distributions, have been based on ovaries and have utilized various formulations of the gonosomatic index for the classification of condition. Oogenesis begins with the proliferation of oogonia by mitotic divisions within the oogonial nest, which become primary oocytes. The oocytes considered within this developmental category are unyolked. It is found that the initial primary oocyte has a relatively narrow, densely staining basophilic cytoplasm and a large clear nucleus.

Biology of kawakawa Euthynnus affinis in the East China Sea: Growth, reproduction, and stable isotope ratios
2024, Regional Studies in Marine Science
This study elucidated the age–growth relationship, maturation body size, and stable isotope ratios of kawakawa Euthynnus affinis in the East China Sea. A total of 396 individuals were collected, of which 266 were captured off the west coast of Kyushu and 130 around Okinawa. Ages were determined from otolith analysis, and the estimated von Bertalanffy growth functions were FL_t = 1007{1 – exp[–0.107(t + 3.835)]} near Kyushu and FL_t = 640{1 – exp[–0.381(t + 1.111)]} around Okinawa, where FL_t is fork length (mm) at age t for ages 0.25 to 5. The estimated fork lengths of the fish near Kyushu were larger than those around Okinawa. The smallest fork length of a fish in the spawning stages was about 440 mm. Mature females and males were observed from May to October near Kyushu and from March to July around Okinawa. Females in the spawning stages were observed from July to September near Kyushu and from April to June around Okinawa. The δ¹⁵N of fish captured near Kyushu (12.39‰ ± 0.55‰, mean ± standard deviation) was higher than that of those captured around Okinawa (9.94‰ ± 1.39‰). This suggests that the kawakawa caught in each area occupy distinct habitats, although some mixing of individuals between the two habitats might occur.
The effect of ocean acidification on otolith morphology in larvae of a tropical, epipelagic fish species, yellowfin tuna (Thunnus albacares)
2023, Journal of Experimental Marine Biology and Ecology
Increasing ocean acidification is a concern due to its potential effects on the growth, development, and survival of early life stages of tuna in oceanic habitats and on the spatial extent of their suitable nursery habitat. To investigate the potential effects of increasing CO₂ on otolith calcification of 9-day old pre-flexion stage yellowfin tuna (Thunnus albacares), an experiment was conducted at the Inter-American Tropical Tuna Commission's Achotines Laboratory in Panama during 2011. Fertilized eggs and larvae were exposed to mean pCO₂ levels that ranged from present day (355 μatm) to two levels predicted to occur in some areas of the Pacific in the near future (2013 and 3321 μatm), and to an extreme value equivalent to long-term projections for 300 years in the future (9624 μatm). The results indicated significantly larger otoliths (in area and perimeter) with significant, and increasing, fluctuating asymmetry at acidification levels similar to those projected for the near future and long-term. Otoliths increased significantly in size despite a significant decrease in somatic length with increasing pCO₂. A consistent correlation between otolith and somatic growth of yellowfin tuna larvae among treatments was evident (i.e., larger otoliths were still associated with larger larvae within a treatment). The observed changes in otolith morphology with increasing ocean acidification have the potential to indirectly affect larval survival through dysfunction of the mechanosensory organs, but this remains to be verified in yellowfin tuna larvae.
Revisiting the spawning fraction of Pacific bluefin tuna (Thunnus orientalis) caught in the Sea of Japan based on diurnal changes in spawning markers
2023, Fisheries Research
The spawning fraction (SF) is an important reproductive trait used to assess the reproductive potential of indeterminate spawning fishes. To estimate the SF more accurately, the durations of spawning markers in ovaries need to be determined. The SF of the Pacific bluefin tuna Thunnus orientalis (PBF) in the Sea of Japan (SOJ) is higher than the SFs in its other main spawning grounds. The present study aimed to revisit the SF of the PBF in the SOJ by focusing on diurnal changes in spawning markers and estimating the duration of spawning markers in PBF ovaries. According to diurnal changes in the postovulatory follicle (POF) degeneration process and final maturation process of oocytes, POFs were observed in ovaries up to 38.5 h after ovulation. The revisited total SF throughout the spawning season was 0.34–0.43 in Area 1 and 0.50–0.64 in Area 2; these values are smaller than the SF previously estimated in the SOJ. The estimated SF of the PBF in the present study was equal to or slightly higher than that in the water between the Nansei Islands, Japan, and the northeast of the Philippines and higher than that in the Kuroshio-Oyashio transition area.
Spatial variation in bigeye tuna Thunnus obesus size at sexual maturity in the eastern Pacific Ocean
2023, Aquaculture and Fisheries
Understanding the reproductive characteristics of a species is of crucial for accurate stock assessment and management plans to ensure sustainable fisheries. In this study, the size at 50% sexual maturity (L₅₀) parameters in different bio-ecological provinces were estimated for bigeye tuna, Thunnus obesus, sampled from the Eastern Pacific Ocean tuna fisheries-dependent survey from 2013 to 2019. The overall sex ratio of the catch during the sampling differed significantly from 1:1. Bigeye tuna exhibit sexual dimorphism in the growth of males and females, with a clear shift in predominance from female to male with increasing sizes. In the North Pacific Sub-tropical Gyre (east) (NPST-east), North Pacific Tropical Gyre (NPTG), Pacific North Equatorial Countercurrent (PNEC), and Pacific Equatorial Divergence (PEQD), females (meals) reached sexual maturity round 102 cm (106 cm), 106 cm (100 cm), 125 cm (110 cm), and 113 cm (110 cm), respectively, the estimated L₅₀ of bigeye tuna was 124.08 cm, 121.97 cm, 139.92 cm and 132.45 cm, respectively. The degree of populations mixing between equatorial (PNEC and PEQD) and high-latitude regions (NPST-east and NPTG) is extremely small, but it is reasonably high between the NPST-east and NPTG or PNEC and PEQD. These parameters were significantly different, suggesting the occurrence of a spatial difference in the size-at-maturity of bigeye tuna between these bio-ecological provinces. The findings of this study provide the key information for understanding the life history of bigeye tuna in the Eastern Pacific Ocean and will contribute to the conservation and sustainable yield of this species.
Reproductive biology of yellowfin tuna (Thunnus albacares) in the northcentral U.S. Gulf of Mexico
2023, Fisheries Research
The reproductive biology of yellowfin tuna (Thunnus albacares) was investigated from fish collected throughout 2000–2017 in the northcentral U.S. Gulf of Mexico (GOM; n = 1135 females, 776 males), predominately from recreational anglers fishing off the Mississippi River (93 %). Histological evidence, along with mean gonadosomatic index (GSI) values, showed that peak spawning occurred from May to August, with the highest mean GSI value for both sexes observed in May (females, 1.52 %; males, 0.57 %). During the reproductive season, the amount of active spermatogenesis in spawning capable males varied monthly as observed by the progression of germinal epithelium (GE) subphases (i.e., early-GE, mid-GE, late-GE), with the mid-GE subphase observed most frequently throughout the peak spawning season. The upper and lower 95 % confidence intervals among length at 50 % maturity (L₅₀) estimates had the largest degree of separation between the physiological (cortical alveoli, L₅₀ =1002 ± 7.18 mm CFL) and functional maturity thresholds (primary or secondary vitellogenesis; L₅₀ =1071 ± 4.89 mm CFL), indicating that the physiological maturity threshold should be used with caution as it may underestimate L₅₀. Using the postovulatory follicle (POF) method, the minimum spawning interval was estimated during peak spawning months for all functionally mature females at 2.10 days, with a minimum of 17.30 % daily spawning. Batch fecundity estimates for 24 females was linearly related to size and ranged from 37,956–6.2 million eggs per batch. These data allow for U.S. GOM reproductive parameter estimates to be incorporated, for the first time, into future Atlantic yellowfin tuna stock assessments done by the International Commission for the Conservation of Atlantic Tunas.
Reproductive dynamics of Pacific bluefin tuna (Thunnus orientalis) off the Nansei Islands, southern Japan
2022, Fisheries Research
To describe seasonal changes in the reproductive traits of Pacific bluefin tuna (Thunnus orientalis), we examined the spawning season, spawning fraction (SF), spawning interval, batch fecundity (BF) and monthly changes in the horizontal distribution of spawning fish (SP) in the Nansei Islands and the waters off southwestern Honshu Island, Japan. SP were observed at sea surface temperatures (SSTs) between 19 and 29 °C, and the frequency of SP tended to increase with SST. SP were observed from early May to mid-July and most frequently in late June. The SP distribution in the Nansei Islands tended to expand northward with time. Mature female fish were widely distributed between the Nansei Islands and the waters off southwestern Honshu Island throughout the study period. The total SF during the spawning season was 0.24, which was equal to the 4.17-day spawning interval. The SF tended to increase with time. The number of days since the start of the fishing season (Days) positively affected the probability of the occurrence of specimens with postovulatory follicles among mature fish. The mean and relative BFs during the spawning season were 9.74 ± 6.72 (million oocytes) and 64.8 ± 38.4 (oocytes/g), respectively. The BF was positively affected by increases in the fork length (FL) and Days. These results suggest that the reproductive traits of Pacific bluefin tuna in the Nansei Islands are influenced by environmental and maternal conditions.
