“…Investigation of genetic background is an essential precondition for fishery resource management [9]. However, most studies on H. nehereus have been conducted focusing on stock assessment, morphological traits, biological habits and nutrition processing [10][11][12][13], and limited studies involve the field of genetics. For example, these studies include population genetic structure and genetic variation analysis based on simple sequence repeat (SSR), sequence-related amplified polymorphism (SRAP) and mitochondrial DNA (mtDNA) markers [14][15][16][17], the molecular phylogenetic relationship revealed by mtDNA Cyt b, 16S rRNA and the complete mtDNA genome [17][18][19], and the expression analysis of calcium cycling genes by transcriptome sequencing [20].…”

Harpadon nehereus forms one of the most important commercial fisheries along the Bay of Bengal and the southeast coast of China. In this study, the genome-wide survey dataset first produced using next-generation sequencing (NGS) was used to provide general information on the genome size, heterozygosity and repeat sequence ratio of H. nehereus. About 68.74 GB of high-quality sequence data were obtained in total and the genome size was estimated to be 1315 Mb with the 17-mer frequency distribution. The sequence repeat ratio and heterozygosity were calculated to be 52.49% and 0.67%, respectively. A total of 1,027,651 microsatellite motifs were identified and dinucleotide repeat was the most dominant simple sequence repeat (SSR) motif with a frequency of 54.35%. As a by-product of whole genome sequencing, the mitochondrial genome is a powerful tool to investigate the evolutionary relationships between H. nehereus and its relatives. The maximum likelihood (ML) phylogenetic tree was constructed according to the concatenated matrix of amino acids translated from the 13 protein-coding genes (PCGs). Monophyly of two species of the genus Harpadon was revealed in the present study and they formed a monophyletic clade with Saurida with a high bootstrap value of 100%. The results would help to push back the frontiers of genomics and open the doors of molecular diversity as well as conservation genetics studies on this species.

“…The adult H. nehereus begin to swim from wintering waters (e.g., the East China Sea, the Yellow Sea) to nearshore waters in spring (Luo et al, 2012). Under the right conditions, the spawning brood stock of H. nehereus migrates to the offshore areas and estuaries to spawn (Taqwa et al, 2020;Wang et al, 2021). Salinity and depth were the most powerful predictors for H. nehereus distribution in spring.…”

Coastal waters provide an important spawning and nursery ground for offshore marine organisms. To understand the suitable habitat and distribution of Harpadon nehereus, a key nearshore species, this study assessed the survey data of fishery resources and environment in Zhejiang’s nearshore fishery in Spring of 2017 to 2020. We used the generalized additive model (GAM) and random forests model (RF) to analyze the environmental factors affecting the selection of spawning habitats by H. nehereus and analyzed the suitable habitat characteristics of H. nehereus in nearshore fisheries. Our results indicate that H. nehereus is widely distributed in Zhejiang’s nearshore and that its density is higher in waters near islands and reefs. Among the relative importance scores of predictors calculated based on RF, seawater salinity is an important environmental factor affecting the distribution of H. nehereus in April (surface seawater salinity was 38.67% and bottom seawater salinity was 34.5%), followed by depth (34.19%), whereas the change in water temperature had no obvious effect on H. nehereus distribution. The suitable habitat characteristics of H. nehereus mainly include high salinity near a water depth of 40 m and a water area with sea bottom dissolved oxygen levels < 6 mg/L. The prediction results of the model indicate that the suitable habitat of H. nehereus is mainly located in the region near Zhoushan Islands in the north of the fishing grounds. Overall, these results may serve as a basis for determining the protection strategies of key nearshore species and enhancing fishery management units.

Nomei (Harpodon nehereus) is a which is found in the northern waters of Tarakan City which has a fairly high economic value. The purpose of the study to analyze the growth patterns and condition index of the fish in Tarakan waters. The research was conducted in two periods, namely the period January-February 2022 and June-July 2022. The research method used a quantitative descriptive method. Fish samples were collected from fisher and data observed were total length, total weight, and sex. In January, the sampled H. nehereus consisted of males (n = 69) and females (n = 231) with allometric negative growth and both fat (male = 50.7%) and thin (female = 48.1%) body type were found. In February 2022, the growth of males (n = 70) and females (n = 224) were positive allometric and both type of body shape were found, with sex ratio of male 48.6% and female 51.4%. In June 2022, the growth of males (n = 980) and females (n = 680) were negative allometric with body shape of both fat (male = 48.1%) and thin (female = 48.5%). In July 2022, the growth of male (n=1197) and female (n=822) were negative allometric with body shape fat (male=49.1%) and thin (female 47.8%). A better management of aquatic biological resources, especially the stock of nomei fish (H. nehereus), is crucial for a sustainable resource.
