“…However, this approach incurs significant costs and cannot be universally applied to all species. Despite these challenges, otolith microstructure analysis remains the most commonly used and reliable approach for age determination in teleost fishes [34]. The analysis provides a powerful tool for gathering essential biological data particularly well-suited for investigating the age, growth, and survival rate of early-stage fish [38,39].…”

“…Otoliths are small calcareous structures found in the inner ear of fish that function as valuable repositories of their life history [31,32]. Unlike other structures, otoliths possess resistance to reabsorption and continuous growth, providing critical insights into fish life and growth, thus making them indispensable tools in ecological fish studies [29,[33][34][35]. Various innovative methods using sophisticated technology have been employed in fish age determination [31,36,37].…”

Japanese anchovy (Engraulis japonicus) is a small pelagic fish with commercial and ecological importance. In spite of its importance, in recent years, specific research on anchovy in the Shandong Peninsula area has been relatively scarce and outdated. This study aims to estimate the age and growth characteristics of anchovy through year-round seasonal sampling from 2016 to 2017, utilizing length–frequency and otolith microstructure analysis. The higher coastal abundance and larger size observed in the spring and summer suggest a potential peak spawning period for anchovies dominated by larger-sized individuals. Based on otolith analysis, anchovies range in age from 0 to 4 years, with a limited presence at age 0 and dominance in the age-1 group. The length–weight relationship (LWR) equation shows hyper-allometric growth for each season, with a mean relative condition factor (Kn) of 1.025 ± 0.005, indicating good health. Additionally, the von Bertalanffy growth equation of can be expressed as Lt = 154.40 [1 − e−0.604 (t + 0.965)], suggesting a medium growth rate (K = 0.604). These findings contribute to the understanding of anchovy age and growth patterns, emphasizing the continuous need for research and monitoring to support rational and sustainable fisheries management and conservation efforts.

“…This study aimed to provide baseline information on the life-history parameters of this species, such as the length-weight relationship, sex ratios, and condition factor. For sustainable management, more studies on fish growth are necessary (Vieira 2023). Therefore, this study serves as fundamental information for understanding the growth characteristics of L. savala in Lampung Bay.…”

Abstract. Julian D, Reza M, Putra MGA. 2024. Length-weight relationship and condition factors of Lepturacanthus savala in Lampung Bay, Indonesia. Biodiversitas 25: 510-515. Scarce information exists regarding the growth aspects of ribbon fish (Lepturacanthus savala Cuvier, 1829) in Lampung Bay waters. Thus, this study aimed to analyze the growth characteristics as fundamental information for managing L. savala fishery resources in the waters of Lampung Bay. The method of this quantitative and descriptive study was to analyze the growth of L. savala. Length, weight, and sex ratio data were acquired through a purposive sampling method based on the catch results from gillnet landings at Lempasing Fishing Port, Bandar Lampung. A total of 347 specimens were collected during data collection from May to August 2023, with a length range between 21.6-59.8 cm of total length (TL) and the highest frequency observed in the length interval class of 33-36 cm, consisting of 105 specimens. The results showed that the growth pattern of L. savala is positively allometric, with a value of b equal to 3.0915. The sex ratio between males and females is 1:2.4. The condition factor values ranged from 0.0442 to 2.9281, with the highest average value observed in June for males and females, reaching 1.03.
