“…It is common in coastal waters with an extensive geographical distribution ranging from the Sea of Japan, around the Indian subcontinent to the Arabian Gulf (Haedrich, 1967). Few but contradicting reports related to the reproductive biology of silver pomfret are available (Gopalan, 1969; Pati, 1981; Abu‐Hakima, 1984; Kim and Han, 1989; Dadzie et al., 1998, 2000a; Almatar et al., 2000).…”

“…Studies on fecundity of silver pomfret are limited to counting the standing stock of advanced yolked oocytes (Pati, 1981; Abu‐Hakima, 1984; Dadzie et al., 2000a), assuming determinate fecundity (Hunter et al., 1992). Recent studies indicate that many temperate and tropical fish have an indeterminate fecundity (Hunter and Goldberg, 1980; DeMartini and Fountain, 1981; Conover, 1985; Hunter and Macewicz, 1985; Greer Walker et al., 1994; Lowerre‐Barbieri et al., 1996).…”

Silver pomfret, Pampus argenteus, were collected by fishing with drift gillnets on one spawning ground in Kuwait waters during 1998Kuwait waters during -2000. Fish size frequency, sex ratio, maturation cycle, spawning frequency, fecundity and egg weight were assessed. The length-weight relationship differed between sexes whereby females were significantly bigger than males. Spawning started in mid-May and continued until early October. During this time the water temperature ranged from 26.0 to 32.8°C, salinity was @ 39.0& and water depth ranged between 5 and 12 m. Large females spawned earlier than young spawners and the overall percentage of males during the spawning period was 70.3%. Spawning occurred after 13.00 h, with peak spawning between 15.00 and 18.00 hours during outgoing tide. Mean daily spawning frequency amounted to 63.2%. Spawning activity was found to be associated with the lunar cycle and spawnings were concentrated during the first and third quarters of the moon period, indicating a semilunar reproduction cycle. It was concluded that a female would spawn at least six times during the season. No change was observed in relative fecundity during the peak spawning season (June-August). Average relative batch fecundity was 176.3 eggs g )1 somatic weight (SW), corresponding to a relative total fecundity of 1058 eggs g )1 SW, which is 1.5 times higher than estimates obtained from counting the standing stock of oocytes. Bigger fish produced heavier eggs and the egg weight decreased as the spawning season progressed. Based on gonadal cycles, oocyte size frequency distribution and total fecundity, we concluded that silver pomfret is a multiple batch spawner with indeterminate fecundity.

“…Por outro lado, exemplos como os de Dadzie et al (2000) e Stequert et al (2003) permitem descrever a fecundidade de forma linear tanto para o comprimento quanto para o peso corporal. Godinho et al (1977) descreveram baixos coeficientes de correlação entre fecundidade e comprimento ou peso, os quais são indicativos de grande variação na fecundidade para peixes de um dado comprimento e peso, refletindo variações nas condições alimentares.…”

Foram determinados os tamanhos dos ovócitos e as fecundidades residual e relativa ao peso de corpo, ao comprimento padrão, ao peso do ovário e ao peso de corpo do líquido dos ovócitos vitelogênicos, e a fecundidade absoluta de 230 fêmeas de manjubas (Curimatellalepidura) coletadas no reservatório de Três Marias, rio São Francisco, MG durante três anos de coleta. Foi utilizado o método gravimétrico para determinar a quantidade de ovócitos vitelogênicos, que foram separados dos avitelogênicos, por diferença de peso. O diâmetro médio dos ovócitos foi de 711±44µm. O valor médio da fecundidade absoluta foi de 60.994,9±27.142,7 ovócitos por fêmea no estádio 2C de maturação (maduro). A fecundidade média relativa ao peso corporal e ao peso do ovário foi de 1.294,1±437,5 e 8.293,8±1.961,9 ovócitos por grama, respectivamente. Não houve diferença significativa (P<0,05) entre as fecundidades absolutas médias nos três anos de pesquisa. Foram encontrados elevados coeficientes de correlação, e os modelos lineares e potenciais foram os mais adequados para expressar as fecundidades absolutas e relativas, ou seja, quanto maior o grau de maturidade, maior a fecundidade dos peixes

“…Such as, Peprilus triacanthus's ovaries were described as symmetric and paralleled organs, fused at the posterior portion, having triangular-circular cross-sectional form and localized completely in the visceral cavity (Kobelkowsky, 2012). The ovaries of Pampus argenteus and Stromateus stellatus present an asynchronous development, which is consistent with partial spawning mode (Dadzie et al, 2000;Almatar et al, 2004;Lone et al, 2008;Carocca & Chong, 2010). The development of ovaries of Peprilus burti was briefly described by eight morphochromatic phases: immature, maturing virgin, early developing/resting, late developing I, late developing II, gravid, ripe and spawning/ spent (Murphy & Chittenden, 1991).…”

1 MALDONADO-AMPARO, M. A.; SÁNCHEZ-CÁRDENAS, R.; SALCIDO-GUEVARA, L.A. & RAMÍREZ-PÉREZ, J. S.Gonadal development of Peprilus medius (Peters, 1869) (Perciformes: Stromateidae) from southeast of the Gulf of California, Mexico. Int. J. Morphol., 35(1):56-61, 2017. SUMMARY:The gonadal development assessment is a fundamental work in researching the reproduction of Peprilus medius, on the way to understand its population dynamics and to achieve a sustainable management of its fisheries. The diagnosis based on morphochromatic features is the quicker, more practical and cheaper method, and properly validated, it may be an accurate procedure. This is particularly useful in researches when it is required to provide prompt and accurate information to support decision-making for fisheries management, and during long-term fisheries monitoring to detect changes in reproductive patterns due to environmental anomalies. These are issues of concern in P. medius and other fishery resources. In this context, a scale that describes the gonadal development through morphochromatic and histological features is presented, and plus anatomical observations of the reproductive organs. Ovarian development was characterized through six phases: immature, development (sub-phases: early and late), mature, spawning (sub-phases: partial and partial post-spawning), post-spawning and resting. Testicular development was described through five phases: immature, development, ejaculation, ejaculated and resting. The position and shape of the reproductive organs are apparently defined by the shape of the fish and the visceral cavity. P. medius's gonads show a gonadal lobe at lower position and an upper lobe in the visceral cavity, and both lobes presented a horizontal placement from gonopore toward the back of the fish. In addition, gonadal deformities occurrence due to deformities in the visceral cavity was evidenced. We recommend to use presented descriptions as a guide in gonadal assessment.
