“…Stearns (1992) suggested that sexual selection strongly favors larger male size in polygynous mammals, whereas fecundity selection favors larger females in fishes, because fish fecundity increased isometrically with body weight. However, male-biased body sizes have been reported in some fish species that show intense competition between males for females (Beacham and Murray 1985;Blair et al 1993;Katano 1998;Quinn et al 2001). In addition, patterns of sexual size dimorphism sometimes vary among populations within fish species, and the variation in the relative strengths of sexualselection and fecundity-selection would produce the observed sexual size dimorphism pattern (Holtby and Healey 1990;Tamate and Maekawa 2006).…”

To examine the potential linkage between sex-biased growth and dispersal in demersal fish, we studied the movement distance and growth of tagrecaptured sablefish (Anoplopoma fimbria). Tagging was conducted by teams from Japan and the United States. From 1980 to 1984, 58,918 sablefish were captured by Japanese vessels and tagged with anchor tags, and between 1980 and 2007, 3319 sablefish were recaptured in the Bering Sea and northeastern Pacific. Of these 3319 fish, we analyzed data on 659 individuals for which we have reliable data on recapture location, sex and fork length at the time of release and recapture, and elapsed time longer than 10 days. Annual growth increments (mean±S.D.) were 2.5±6.5 cm (males) and 3.5±8.6 cm (females), and the movement distances (assumed to be straight) were 712±800 km (males) and 877±920 km (females). Females grew larger and moved longer distances than males. We calculated the growth increment deviation that accounted for the effects of elapsed time, curvilinear growth, and initial fork length at release using a von Bertalanffy growth model. The growth increment deviation increased significantly with the distance moved over elapsed time. In addition, the relationship between distance moved over elapsed time and the growth deviation differed significantly between sexes; females grew faster than males at a given movement distance. We suggest that femalebiased dispersal is a factor generating female-biased growth in sablefish.

“…Thus, newly hatched larvae of C. sieboldii are smaller than those of C. temminckii. At our study site, however, growth rates of C. sieboldii after hatching were higher than that of C. temminckii observed by Katano (1998). Katano (1998) also suggested that the growth rates of C. temminckii were highest from April to May, and those of males Figure 6.…”

We investigated the breeding season, growth rate and dispersal of the dark chub, Candidia sieboldii, an endangered species in Japan. A markrelease-recapture survey was performed in three branches of the Ishizu River system in Osaka Prefecture, Japan, between May 2012 and August 2013. A total of 963 individuals were marked in one river branch and 275 (29%) were recaptured at least once in the same river section. The breeding season was determined to be June-August, and the size at maturity for both males and females was estimated at about 70 mm standard length. Growth rates calculated from standard lengths of recaptured individuals were higher between April and September than between October and March. Among 963 marked individuals, only a single fish was found 500 m downstream from the release point. Moreover, although we released 409 more marked individuals in the three branches to follow inter-branch dispersal between September and December 2013, we observed none. These results indicate that this species has low dispersal and a short lifespan of 1-2 years. This short lifespan could increase the risk of breeding failure, and the low frequency of dispersal, restricted by weirs, could make population re-establishment and recovery difficult.

“…Further, from the fi gure in Marconato and Rasotto (1989), growth rates in size from May to July (the breeding season) can be perceived to be smaller than those from July to September (after the breeding season). Males of both the Japanese fl uvial sculpin Cottus pollux (see Natsumeda et al, 1997) and the dark chub Zacco temmincki (see Katano, 1998), which show male-biased SSD and whose male mating success depends on the body size, were reported to grow even in the breeding season. In the present study, Lefua sp.…”

“…S exual size dimorphism (SSD) has been recognized in many fi shes (Echeverria, 1986;Natsumeda et al, 1997;Katano, 1998;Kohda et al, 2002;Henderson et al, 2003). Male-biased SSD has been ultimately explained mainly as sexual selection for males (male-male interference competition and female choice) (Natsumeda et al, 1997;Katano, 1998) and female-biased SSD mainly as natural selection for females (Echeverria, 1986). Reproductive roles to gain reproductive success for individuals are different between sexes, i.e., maximization of mate acquisition for males and maximization of offspring production for females (Trivers, 1972).…”

The maturation and growth pattern of the fl uvial eight-barbel loach Lefua sp. (Japanese name: nagare-hotoke-dojo), an endangered species, was investigated using an individual identifi cation-recapture method from 1995 to 1998 in an upper reach of a headwater tributary of the Kako River, Hyogo Prefecture, Japan. Based on observations of the gonads through the abdominal skin, the loach was estimated to breed mostly from May to July. All the males matured by age 1 + , and all the females matured by age 2 + . Gamete release in all individuals of both males and females was predicted from recaptured loaches during each breeding season. The standard length of mature females was signifi cantly larger than that of males, showing sexual size dimorphism (SSD). The maximum sizes recorded were 75.4 mm SL for females and 61.2 mm SL for males. Both males and females of immature specimens grew mainly from May to November, including the breeding season, with no signifi cant differences in growth rates between them. After sexual maturity, both males and females grew mainly from July to October (or November), after the breeding season, and the females exhibited higher growth rates than males. Therefore, SSD of the species seems to be attributable to the different growth rates after maturity. The longevity of the loach was estimated to exceed ten years based on individual growth patterns of various sizes during the survey period. It is likely that the loach has an iteroparous life history, breeding every year, and moderate growth rates after maturity.
