“…Moreover, males reached 50% maturity at a smaller size than females, 65.4 and 73.1 mm TL, respectively. This could indicate a different growth rate in each of the sexes (Moreno and Morales-Nin, 2002). Palmer (1979) also observed an increase with age in the proportion of females in this species, and also in A. boyeri females reached larger sizes than males (Castel and Cassifour, 1977;Gon and Ben-tuvia, 1983;Fernández-Delgado et al, 1988).…”

“…Namely, Dorman reported male domination at smaller and female at higher length classes (TL [ 80.0 cm). The observed difference in sex ratio at size is probably due to sexually dimorphic growth patterns (Moreno and Morales-Nin 2003). Additionally, higher difference in sex ratio at size could also be attributed to fishing gear and its vulnerability and selectivity.…”

A recent study concerning the reproductive biology of the garfish (Belone belone, L. 1761) has been carried out in the eastern part of the Adriatic Sea along the Croatian coastline. Specimens of the fish (N = 3,393) were collected over a 6-year period (2003)(2004)(2005)(2006)(2007)(2008). Their length varied between 20.8 and 75.4 cm (mean ± SD = 38.3 ± 7.94). Female garfish were dominant in larger length groups being most apparent during the resting phase of sexual cycle and in the peak of the spawning period, occurring in April and May. The sexual ratio of all specimens was m/f = 0.98. Males were prevalent in March-at the beginning of the highest spawning activities. Fifty percentage of the garfish population sexually matured at 28.5 cm of total length. Males and females reached their sexual maturity at 28.0 and 31.5 cm of total length, respectively. Spawning began in January peaking during March to May. According to their maturity stages, gonad weight and the gonadosomatic index, males began to spawn one month earlier (April) than females (May). The mean batch fecundity of garfish was 1,242.46 ± 843.64 of matured oocytes per ovary. Matured oocyte diameters ranged from 1.223 to 4.283 mm with the mean value of 2.269 ± 0.332 mm.

Pelagic larval duration and settlement sizes in species of Apogonidae, Labridae, Scaridae, and Tripterygiidae in a coral lagoon in southern Japan were examined. Sampling was conducted monthly from July 2004 to June 2005 in the coral lagoon and channel of the Oh-do Beach on Okinawa Island, Japan. Pelagic larval duration was estimated by the number of otolith increments. Mean standard length at settlement of apogonids ranged from 7.7 to 13.9 mm, and mean pelagic larval duration ranged from 14.0 to 30.6 days (14 species, 418 individuals). In labrids, mean standard length at settlement and pelagic larval duration varied greatly (mean standard length: 5.4-11.0 mm; pelagic larval duration: 18-57 days, four species, four individuals). Scarids showed consistent mean standard length at settlement and pelagic larval duration (mean standard length: 7.1-7.6 mm; pelagic larval duration: 29-42 days, five species, 25 individuals). In tripterygiids, pelagic larval duration was more consistent (range: 18-29 days, mean: 22.2 e 2.1 days), but mean standard length at settlement ranged from 7.8 to 10.3 mm (six species, 32 individuals). These results suggest that the pelagic larval duration of Apogonidae and Tripterygiidae (nonpelagic egg spawning) is shorter than that of Labridae and Scaridae (pelagic egg spawning), and the dispersal strategy of labrids and scarids may include wider dispersal than that of apogonids and tripterygiids.The life history of most coral reef fishes includes a pelagic larval phase (Leis 1991).Hatched larvae inhabit open water and grow to become pelagic larvae. These pelagic larvae search for suitable benthic habitats on coral reefs using visual, acoustic, chemical, or other senses before settlement (Montgomery et al. 2001). The length of the pelagic larval duration influences the survival and dispersal of coral reef fishes (Wellington and Victor 1989, Doherty 1991, Cowen 2002.Pelagic larval duration and size at settlement are basic life history characters of coral reef fishes and are important in understanding coral reef ecosystems. Pelagic larval duration can be determined by examining otoliths of fish larvae that reach settlement sites. Pannella (1971) showed that microincrements of otoliths form daily. Many studies have shown that increments in otoliths form daily in both temperate (Kingsford and Milicich 1987) and tropical (Thresher et al. 1989, Moreno andMorales-Nin 2003) reef fishes. Researchers have estimated the pelagic larval durations of some coral reef fishes by the number of otolith increments of larvae and juveniles just before or after settlement (Brothers et al. 1983,
