“…Individual relative fecundity ( F R ) was defined as F B divided by M R of females (Hunter et al., ): F R = F B × M R −1 . Since K. audax have indeterminate batch fecundity, individual annual fecundity ( F A ) was estimated from F B , spawning frequency ( F S ) and the duration of spawning season ( S S ) (Arocha & Bárrios, ): F A = F B ( F S ) −1 × S S .…”

“…24 h after spawning (Hunter et al ., ; McPherson, ; Nikaido et al ., ; Schaefer, ) and degeneration has been reported to show a strong correlation with temperature (Fitzhugh & Hettler, ). The spawning of many large pelagic species appears to show concordance with temperatures of about 24° C (Schaefer, ; Young et al ., ; Arocha & Bárrios, ) and actively spawning K. audax have been documented at temperatures of 24·8–28·3° C (Kopf et al ., ). Therefore, using the degeneration rate of tuna POFs as an approximate guide, it was assumed that the POFs of K. audax were histologically detectable until 24 h after spawning.…”

Length and mass data for 1260 (536 females, 683 males, 41 sex unknown) striped marlin Kajikia audax were collected at the fish markets of Tungkang, Singkang and Nanfangao from July 2004 to September 2010. Of these samples, 534 gonads (236 females and 298 males) ranging from 95 to 206 cm in eye-to-fork length (L EF ) and 8 to 88 kg in round mass (M R ), were collected. Chi-square tests indicated sex ratios were homogeneous among months in 2004 and 2006-2008, but not in 2005, 2009 and 2010; and there were significant differences in sex ratio by size. The overall sex ratio (R S ) differed significantly from the expected 0·5. Kajikia audax are sexually dimorphic and the proportions of females increased with size between 140 and 210 cm L EF . Reproductive activity was assessed using a gonado-somatic index (I G ), external appearance of the gonads and histological examination and results indicated that the spawning season occurred from April to August with a peak in June to July. Based on histological observations and the distribution of oocyte diameters, K. audax are multiple spawners and their oocytes develop asynchronously. The estimated length-at-50% maturity (L EF50 ) was c. 181 cm (c. 4·8 years of age) for females. The proportion of reproductively active females in the spawning season with ovaries containing postovulatory follicles (0·27) indicated that they spawned every 3·7 days on average. The hydrated oocyte method estimated mean ± S.D. batch fecundity (F B ) to be 4·4 ± 2·02 million eggs; average relative fecundity was 53·6 ± 13·9 oocytes g −1 M R ; and the average annual fecundity was 181·3 ± 48·3 million eggs. The parameters estimated in this study are key information for stock assessments of K. audax in the north-western and central Pacific and will contribute to the conservation, management and sustainable yield of this species.

“…Spawning is reported to occur in a broad area through the tropics, (Nakamura, 1985), and regional studies have provided insights into spawning seasons in particular regions (Prince et al, 2005;Arocha and Bárrios, 2009;Rooker et al, 2012). Conventional tagging of white marlin has occurred primarily in the western North Atlantic (reviewed in Ortiz et al, 2003) and results demonstrate considerable movements within that region.…”

“…Batch spawning is commonly found in a variety of marine tropical pelagic fishes which permits fish to increase fecundity as well as the chances for spawning success and survival of eggs and larvae (Hunter et al, 1985;Hunter and Macewicz, 1985a, b;Sadovy, 1996;Arocha and Bárrios, 2009). Large size snapper species, such as the mutton snapper L. analis, performs mass spawning aggregations and can persist for many days in the spawning grounds (Burton et al, 2005;Kojis and Quinn, 2011).…”

Lutjanid species exhibit multiple spawning behaviour during an extended spawning season in warm months, asynchronous oocyte development and indeterminate fecundity. Although early studies have contributed to knowledge of the reproductive cycle of many species within the group, they have not considered aspects about the number of cortical alveoli oocyte stage throughout maturity phases along spawning season. The latter aspect is also considered very important to confirm indeterminate fecundity hypothesis. In the present study, were analyzed 154 Brazilian snapper Lutjanus alexandrei female gonads obtained from artisanal fisheries in Pernambuco State (Brazil) between October 2010 and March 2011. Were measured oocyte size frequency distribution for maturity phases (developing, spawning capable and actively spawning), and oocyte development stage (unyolked oocytes, cortical alveoli, primary, secondary and tertiary vitellogenic oocytes and hydrated oocytes), and also the oocyte stage frequency during spawning season. The frequency of cortical alveoli oocyte stage was constantly found in the spawning period (>37%), showing slight variation throughout maturity phases. The absence of gap in the oocyte size frequency distribution between primary and secondary oocyte growth stages during spawning season is a strong indicator of continuous oocyte recruitment from reserve stocks. In addition, co-occurrence of tertiary vitellogenic oocytes, hydrated oocytes, post-ovulatory follicles and yellow-brown bodies in the histological sections of ovaries reinforce indeterminate fecundity hypothesis.Keywords: multiple spawning, asynchronous development, ovulation.Desenvolvimento ovocitário e tipo de fecundidade da baúna de fogo Lutjanus alexandrei Moura & Lindeman, 2007 (Perciformes: Lutjanidae) ResumoOs lutjanídeos apresentam um comportamento de desovas parceladas ao longo de uma extensa estação reprodutiva nos meses mais quentes do ano, desenvolvimento assincrônico dos ovócitos e padrão de regulação de fecundidade indeterminado. Embora muitos estudos anteriores tenham contribuído no conhecimento do ciclo reprodutivo das espécies do grupo, não foram considerados os aspectos relacionados ao percentual dos ovócitos em estágio de cortical alveoli entre as fases de maturidade sexual durante a estação reprodutiva. Este último aspecto, considerado importante para confirmação da hipótese de fecundidade do tipo indeterminada. Para isso, no presente trabalho foram analisadas 154 gônadas de fêmeas da baúna de fogo Lutjanus alexandrei obtidas da pesca artesanal em Pernambuco entre o período de outubro de 2010 a março de 2011. Foram mensurados os diâmetros dos ovócitos nas fases de maturidade sexual (desenvolvimento, capaz de desovar e ativamente desovando), e para todos os estágios ovocitários (ovócitos pre-vitelogênicos, cortical alveolar, vitelogênese primária, secundária, terciária e ovócitos hidratados), e avaliada a frequência de ocorrência ao longo do período de desova. O percentual de ovócitos em estágio cortical alveoli permanece...
