Age, Growth, Maturation, and Mortality of Grass Goby Zosterisessor ophiocephalus (Gobiidae) of the Karkinitsky Gulf, the Black Sea

Age and Growth of Japanese Anchovy (Engraulis japonicus, Temminck & Schlegel, 1846) in Coastal Waters around Shandong Peninsula, China

“…The growth coefficient (K) of anchovies calculated in this study was 0.604, which falls within the category of medium growth according to the classification proposed by Sparre and Venema [55]. This relatively higher growth coefficient (K) value suggests that the maximum asymptotic length will be attained more quickly, a characteristic often observed in fish species with short life cycles [84]. Compared with previous studies (Table 3), our findings show a growth coefficient (K) value consistent with those reported previously.…”

Age, growth, maturity and mortality of the tapetail anchovy Coilia brachygnathus (Engraulidae) in Lake Honghu, China

“…This contrasts with McCarthy and Marriott's (2018) and Kutsyn et al .' s (2022) finding that the latitude decreases while the growth rate ( K ) increases. Relatively, a slight lower growth performance index ( ɸ′ ) of Lake Changhu in comparison to the Three Gorge Reservoir is likely related to its lower asymptotic length ( L ∞ ) (Table 3), which is highly affected by intensive fishing pressure (Basilone et al ., 2017; Samsun et al ., 2006; van Beveren et al ., 2014).…”

“…In this study, the K values of the male (0.206–0.209 year −1 ), female (0.34–0.36 year −1 ) and both (0.33 year −1 ) of C. brachygnathus from Lake Honghu were greater than 0.20, thus indicating that the fish is a rapid‐growing species. High values of the K coefficient revealed the rapid achievement of the maximum asymptotic length, which is typical for species with a short life cycle (Kutsyn et al ., 2022). The rapid growth of the C. brachygnathus population in Lake Honghu is affirmed by higher growth performance index ( ɸ′ ) values of 2.66, 2.41 and 2.58 for females, males and both, respectively, compared with most of the other lakes (Figure 7).…”

“…This difference might be explained by the fact that Lake Changhu was sampled before 2020, while the Three Gorge Reservoir sample was conducted after 2020 when 10 years of closed fishing in the Chang‐Jiang started to be implemented. The increase in the growth rate and growth performance index along with the longitudinal gradient is mainly attributed to water temperature and diet availability (Basilone et al ., 2017; Kutsyn et al ., 2022; McCarthy & Marriott, 2018).…”

“…Similar studies have been reported by Stewart and Hughes (2007), McCarthy and Marriott (2018), and Kutsyn et al . (2022) from other fish species, and this is a phenomenon common in most animals where females mature earlier than males (Ancona et al ., 2020). No comparisons can be made here with other Chinese congeneric species because there are no analyses on the size and age at 50% maturity of these fishes.…”
