“…That of the same spp harvested from the Gulf of Carpentaria CROCOS, 1987 was even higher (17.0 cm) than that reported by KING, 1995 . Both reported estimates were comparable with each other, considering the geographic and temporal separation of their studies.…”

A total number of 338 specimens of Macrobrachium vollenhovenii were bought from fisher folks who fished from Ubeji, Jala and Soroghagbene; but marketed their landings at Ubeji. Specimens were collected at monthly intervals between March and November, 2011. The male to female sex ratio established was 1:2:3. The size at first maturity was 9.0 cm for males and 10.0 cm for females. The length-weight relationship revealed an increase in total length of each specimen as body weight increased. The regression coefficient 'r' was significant at p< 0.05 for male (0.901) and female (0.644) specimens. An average condition factor of 3.9 and 2.74 was recorded for males and females respectively. The Gonado-Somatic-Index (GSI) was generally higher, especially during the month of July for females (0.60) than for males (0.50). Distinct histological changes were observed in the gonads of both sexes. Gonad development revealed five distinct stages (dominant, developing, developed, ripe and spent) for both sexes. Fecundity ranged between 5,540-28,470 eggs, and was highly correlated with total length (0.979) but not with body weight (0.185). Fecundity was highest in the month of July (20,113) and lowest in the month of August (6,140). It could be concluded that matured specimens probably spawn, in March and in July, when GSI were at their peaks. This pattern of breeding suggests that they were capable of multiple spawning within a single reproductive season.

“…The occurrence of breeding peaks followed by recruitment peaks indicates fitness in the population (Crocos, 1987). Crocos and van der Velde (1995) proposed the term "effective spawning" when the reproductive activity of a given population contributes to the following recruitment within that same population.…”

Population biology of the commercially exploited shrimp Artemesia longinaris (Decapoda: Penaeidae) in an upwelling region in the Western Atlantic: comparisons at different latitudes

This study characterized the population biology of the dendrobranchiate penaeid shrimp Artemesia longinaris Spence Bate, 1888, focusing on population structure, sexual maturity, reproductive period and recruitment, and comparing reproductive parameters of a different populations along western South Atlantic..Samples were collected monthly from March, 2008 to February, 2010 in Macaé, northern coast of Rio de Janeiro State, Brazil, a region influenced by the Cabo Frio upwelling. There was a significantly higher percentage of females and with larger sizes than males. Both carapace length and sexual maturity in Macaé were similar to the dimensions found in populations in the South of the continent (Argentina). Reproductive females were present in all months, with main peaks during winter and summer. Recruitment was also continuous, with peaks, usually one to two months after the appearance of reproductive females, after the reduction of the bottom temperature values of water. These data suggest that November to January would be the appropriate months for legal off-season, due to the higher intensity of spawning females and juveniles during this period. A comparação latitudinal dos parâmetros reprodutivos, não confirma o paradigma de que tamanho do corpo e a maturidade sexual das fêmeas são menores em regiões tropicais e aumentam em direção às maiores latitudes, reforçando a hipótese da influência e importância da ACAS na dinâmica reprodutiva de A. longinaris na região The results of this study contribute to the understanding of the biology of A. longinaris, and could also be a reference to monitor this important fishery resource and consequent legal off-season. Furthermore, this population located at the northern limit of the species distribution is a source of highly relevant comparison for population studies in other areas.Keywords: Dendrobranchiata, sex ratio, recruitment, reproductive biology, shrimp fishery.

The reproductive biology including insemination frequency, ovarian maturation, gonadosomatic index (GSI), size at Wrst maturity, and fecundity of Melicertus kerathurus were investigated using monthly samples from Thermaikos Gulf. Insemination was recorded by the presence of a spermatophore in the thelycum, and ovarian development was based on macroscopic ovarian staging (ST1-ST5). Inseminated females were found throughout the year with high percentages recorded from April to July. Although all ovarian stages were represented in mated females, insemination increased with size and ovarian maturation. High percentages of vitellogenic or mature ovarian stages were observed from May to July, while immature and developing ovaries were predominant mainly in winter. Spawned ovaries occurred from May to October. Carapace length at Wrst maturity based on the presence of a spermatophore (CL 50sp ) was estimated at 39.20 mm, while that based on the presence of vitellogenic and mature ovaries (CL 50ov ) at 40.70 mm. The seasonal peak in the proportion of mature females (ST4) varied with size. Inseminated females at ST4 and GSI peaked in June-July. GSI varied in relation to insemination status and ovarian stage. In large females (>50 mm CL), the decline in mature ovaries and GSI increment with size indicates a relative reduction in the reproductive output. The number of oocytes ranged from 62,742 to 602,947 (mean § SD: 268,000 § 113,000). As the prawns are targeted during the spawning season, mainly by the artisanal Wshery, and female size at Wrst maturity is selected by artisanal net size, managerial measures toward artisanal Wshery should be implemented.
