“…It is possible that the maximum length of both female and male specimens collected in this study was larger than those from other regions. Owing to the nature of the model, the greater the size of the collected individuals, the greater the maximum length [37]. Accordingly, it is necessary to collect fish samples in the same manner to analyze the growth differences accurately in each sea area.…”

To investigate the age and growth characteristics of shotted halibut, Eopsetta grigorjewi, in the West Sea of Korea, the samples were collected using gill nets throughout 2019. A total of 861 specimens (693 females and 168 males) were analyzed. The BW-TL relations were BW = 0.0034TL3.3278 (R2 = 0.8716) for females and BW = 0.0031TL3.3359 (R2 = 0.8860) for males. This analysis revealed that males exhibited a larger growth rate than females (p < 0.05). Notably, the anterior and posterior sections of the otolith displayed an elongated oval shape, exceeding the radius of the dorsal and ventral regions. By examining the correlation between radii in four directions and total length, the highest correlation was observed between the total length (TL) and the ventral radius (R). The evaluation of the relationship between the fish total length and the otolith ventral radiusresulted in an equation of TL = 14.657R + 9.1601 (R2 =0.7081) for females and TL = 15.037R + 5.0265 (R2 = 0.6992) for males (p < 0.05). The formation of annuli occurred annually, consistently in January each year, as discerned through monthly changes in marginal index (MI) values. The von Bertalanffy growth equations from the relationship between the otolith annuli radius and the total length were Lt = 83.6 (1 − exp−0.046(t+4.70)) in females (n = 693, p < 0.05) and Lt = 56.8 (1 − exp−0.078(t+2.16)) in males (n = 168, p < 0.05).

“…There are various factors determining the success of aquaculture, including water quality, environmental aspects, genetics, reproduction and life cycles, nutrition, food and feeding, disease, post-harvest technology and processing, and economics and marketing ( Lucas and Southgate, 2012 ). To date, most research conducted on this species is related to ecology, including the development of fertilized eggs, larvae, and juveniles ( Yusa, 1960 ; Han et al., 2001 ), reproduction and population dynamics ( Lee et al., 1985 ; Kang et al., 1985 ; Kume et al., 2006 ; Seo et al., 2010 ), feeding habits ( Huh et al., 2012 ), age, and growth ( Solomon et al., 1987 ; Kim et al., 1991 , 2015 ; Lee et al., 2009 ; Joo and Gwak, 2014 ). Among the factors for successful aquaculture, foods are critical because they generally constitute half of the total production costs.…”

An 8-week feeding trial was conducted to determine the optimal dietary protein level for juvenile marbled flounder. Five semi-purified test diets were formulated to contain different protein levels (CP) including 42.7%, 47.4%, 53.3%, 58.8%, and 64.5% (dry matter), named as CP42.7, CP47.4, CP53.3, CP58.8, and CP64.5, respectively. Five hundred and twenty-five juveniles (6.0 ± 0.1 g) were randomly distributed into 15 tanks (300 L tanks), resulting in 35 fish per tank ( n = 3 tanks). Fish were fed the test diets 5 times per day until satiation. The CP58.8 resulted in the highest gain in weight and the best efficiency in feed utilization among the tested protein levels ( P < 0.05). Fish fed the CP58.8 diet showed significantly higher whole-body protein and lipid contents than the fish that were fed the other diets ( P < 0.05). Fish fed the CP53.3, CP58.8, and CP64.5 diets showed a significantly higher dorsal-muscle lipid content than the fish that were fed the CP42.7 and CP47.4 diets ( P < 0.05). The one-slope straight broken-line regression analysis on the results of the thermal growth coefficient and feed conversion ratio indicated that the estimated optimum dietary protein level was 58.8%. Taken together, it is suggested that the dietary protein level of 58.8% is optimal for better growth and high efficiency in feed utilization for the juvenile marbled flounder.
