“…In sustainable fishery management, it allowed estimation of the stock population, the potential yield of productivity, mortality and recruitment pattern. However, information on growth, mortality and recruitment pattern of mudskippers are limited to several species like Periophthalmus barbarus (Chukwu & Deekae 2010;Etim et al 2002Etim et al , 1996Turay et al 2006), Periophthalmus waltoni (Sarafraz et al 2011), Periophthalmus novemradiatus (Rahman et al 2015), Scartelaos gigas (Kim et al 2011;Park et al 2008), Scartelaos tenuis (Salarpouri et al 2013), Periophthalmodon schlosseri (Mazlan & Rohaya 2008) and Boleophthalmus pectinirostris (Nanami & Takegaki 2005). Currently, the documented knowledge on population parameters of P. chrysospilos is scarcely reported.…”

This study reports the length-weight relationships (LWR), body condition factor (K n) and growth parameters of Periophthalmus chrysospilos in Bayan Bay of Penang, Malaysia. The values of exponent b for all categories of fish were higher than 3 indicating a positive allometric growth. The mean condition factor (K n) for all categories of fish also higher than 1 which reflect the well beings of fish in the study area. The b values of LWR and condition factors for male was similar to female fish, but the b values of LWR and condition factors were significantly higher in rainy months compared to the dry months. The parameters of population dynamic show the asymptotic length (L∞) of 13.20 cm, growth coefficient (K) of 0.68 year-1 , growth performance index (Ø') of 2.074, total mortality (Z) of 2.47 year-1 , and fishing mortality (F) of 0.70 year-1. The exploitation level (E) was 0.28 year-1 indicating of low exploitation and estimation of length at first capture was 7.69 cm. The annual recruitment pattern of P. chrysospilos was recruited in two peaks per year.

“…Scartelaos gigas (Perciformes, Gobiidae), a kind of mudskipper goby, is restricted to the mud flats of Korea, China, and Taiwan (Murdy, 1989;Lin et al, 1994;Randall and Lim, 2000;Park et al, 2008). In Taiwan, S. gigias is considered in danger of becoming extinct (Dr. Shao, personal communication).…”

“…In Taiwan, S. gigias is considered in danger of becoming extinct (Dr. Shao, personal communication). This fish may be at a high risk of extinction because of its very restricted habitat compared with Boleophthalmus pectinirostris (Park et al, 2008). Regarding habitat character-istics, Kim et al (in preparation) documented that S. gigas prefers to live in mud flats with more than 99% mud, but B. pectinirostris prefers less than 95% mud; accordingly, the former shows a very restricted distribution.…”

“…Regarding habitat character-istics, Kim et al (in preparation) documented that S. gigas prefers to live in mud flats with more than 99% mud, but B. pectinirostris prefers less than 95% mud; accordingly, the former shows a very restricted distribution. Additionally, habitat destruction by indiscreet coastal development by government and overexploitation by fishermen can hasten the extinction of these species (Park et al, 2008). Many studies have focused on the more widely distributed mudskipper, B. pectinirostris, was excavated, following the method of Koga and Noda (1992).…”

“…There have also been many reports on B. pectinirostris in Korea, including studies of its oocyte maturation (Chung et al, 1989), sexual maturation (Chung et al, 1991), age and growth (Jeong et al, 2004), growth of age-0 fish (Kim and Jeong, 2007), and habitat and spawning (Jeong et al, 2010). However, there is no reported study of S. gigas except a single study on its age and growth (Park et al, 2008). This dearth of studies on S. gigas is probably attributable to its very limited habitat compared with that of B. pectinirostris, as mentioned above.…”

Scartelaos gigas is an amphibious mudskipper species that inhabits mud flats in Korea, China, and Taiwan. This fish is at risk of extinction because of its very restricted habitat and overexploitation. Information about this fish's reproductive characteristics is needed for species conservation. The sexual maturity and early life history of S. gigas were investigated through histological methods and direct observation of eggs in the wild, respectively. In total, 560 individuals of S. gigas were collected with the aid of fishermen from March 2003 to October 2003 at Jung-do Island, southwest Korea. Through microscopic observations of gonadal development, it was determined that S. gigas of both sexes were immature in April, but began to reach maturity in May, and were then fully mature by June, which was maintained until July. In August, some female fish developed early oocytes, but by September oocytes were observed to have degenerated and had been absorbed. Spawned eggs were elliptical and had an average size of 1.37 mm (long axis) by 0.69 mm (short axis). The newly hatched larvae (3.03 mm total length, TL) had an open mouth and anus, two melanophores near the anus, and one large melanophore between the 18th and 19th myomeres. The larvae (3.18 mm TL) showed absorption of the yolk and oil globule within 5 days after hatching and became prelarvae. This species should be considered vulnerable or conservation-dependent, and thus parental fish need to be protected from fishermen during the main spawning season (June).
