“…In this study, the lowest gene differentiation was observed between R. lateristriata (cultivated population from Jogjakarta) and natural resources (Malang) (Table 6). The low FST value observed in this study could be explained by the two populations sharing the same parental origin (Doğdu & Turan, 2021). Additionally, connected waters, restocking in the wild from cultured fish, and mass recruitment of fish from nature could be affected by gene differentiation (Duong & Scribner, 2018).…”

“…Similar findings were made in the S. aurata (Šegvić-Bubić et al, 2014) and R. lateristriata (Harris et al, 2021). This character difference is thought due to morphological characteristics inherited from previous generations, the season, food availability, and age (Doğdu & Turan, 2021). Otherwise, R2, R10, R11, and R12 of farmed R. argyrotaenia (Jogjakarta) were the longest than the wild type (Purworejo).…”

“…Fisheries and Aquatic Sciences Martinez et al, 2020). This is because cultured fish are selectively bred to produce offspring with larger body types (Doğdu & Turan, 2021). The fin size of cultured fish can be influenced by aquaculture water settings such as water discharge, stocking density, volume, and feeding (Doğdu & Turan, 2021).…”

The mitochondrial cytochrome c oxidase (COI) gene is widely used as a marker gene for the taxonomic identification of fish.…”

The morphology and genetic identification of Rasbora lateristriata and Rasbora argyrotaenia between cultivated and wild populations has never been reported. This study compares morphology and cytochrome c oxidase (COI) genes between farmed and wild stock Rasbora spp. in Java and Sumatra island, Indonesia. We analyzed the truss network measurement (TNM) characters of 80 fish using discriminant function analysis statistical tests. DNA was extracted from muscle tissue of 24 fish specimens, which was then followed by polymerase chain reaction, sequencing, phylogenetic analysis, fixation index analysis, and statistical analysis of haplotype networks. Basic Local Alignment Search Tool analysis validated the following species: R. lateristriata and R. argyrotaenia from farming (Jogjakarta); Rasbora agryotaenia (Purworejo), R. lateristriata (Purworejo and Malang), Rasbora dusonensis (Palembang), and Rasbora einthovenii (Riau) from natural resources. Based on TNM characters, Rasbora spp. were divided into four groups, referring to four distinct characters in the middle of the body. The phylogenetic tree is divided into five clades. The genetic distance between R. argyrotaenia (Jogjakarta) and R. lateristriata (Malang) populations (0.66) was significantly different (p < 0.05). R. lateristriata (Purworejo) has the highest nucleotide diversity (0.43). R. argyrotaenia from Jogjakarta and Purworejo shared the same haplotype. The pattern of gene flow among them results from the two populations' close geographic proximity and environmental effects. R. argyrotaenia had low genetic diversity, therefore, increasing heterozygosity in cultivated populations is necessary to avoid inbreeding. Otherwise, R. lateristriata (Purworejo) had a greater gene variety that could be used to develop breeding. In conclusion, the middle body parts are a distinguishing morphometric character of Rasbora spp., and the COI gene is more heterozygous in the wild population than in farmed fish, therefore, enrichment of genetic variation is required for sustainable Rasbora fish farming.

An individual of Pempheris rhomboidea species was detected in a cage where sea bream was grown in the Mersin Dana Island region. P. rhomboidea is a species of the Pempheridae family distributed in the Indo-Pacific and West Atlantic and is a nocturnal species that inhabit coral reefs and rocky waters. It is known that different wild fish species enter into the aquaculture fish cages where marine fish are grown and grow together with the aquaculture species. There is no previous record of this species obtained from aquaculture cages. The total length and weight of the individual in the cage were 12.6 cm and 23.938 g. Considering the mesh size of the cage, it is estimated that this individual entered the cage in the juvenile period. At the end of the 11-month aquaculture period, it was determined that the individual reached a length close to the maximum length that the species can reach in its natural habitat. It was determined that some morphometric characteristics of the individuals harvested from the cage were similar to individuals caught in nature. The ability of the nocturnal species to grow in aquaculture cages indicates strong adaptability. Other wild species harvested from the cage at the same time were Oblada melanura, Scomber japonicus, Liza ramada, Diplodus vulgaris, Alosa fallax nilotica, Siganus rivulatus, Trachurus mediterranus, Lichia amia, Argyrosomus regius, Spicara smaris, Coryphaena hippurus. The proportional increase of wild species in aquaculture fish cages may cause economic losses for the companies in the future.

The length-weight relationship data is important basic information that helps to compare species between populations and habitats. In this study, we provide detailed information on the length-weight relationships and condition factors of Lagocephalus guentheri from the Iskenderun Bay, northeastern Mediterranean Sea. A total of 408 (262 Female, 146 Male) specimens were collected on commercial trawlers by local fishermen caught between December 2022 to December 2023 from Iskenderun Bay. The total length range was 11.0-36.9 cm and 11.2-36.7 cm for females and males, respectively. The total weight values of females and males ranged from 20.30-1080.50 g and 20.50-1012.36 g, respectively. The length-weight relationship of L. guentheri was calculated as W = 0.0098 × L3.2145 (R2 = 0.9960) for females, W = 0.009 × L3.2399 (R2 = 0.9963) for males, and W = 0.0095 × L3.2243 (R2 = 0.9962) both sexes. The Fulton’s condition factor was observed as 1.2384 for females, 1.2504 for males, and 1.2335 for both sexes. This study is the most recent reference on length-weight relationships and condition factors for L. guentheri after correction of species identification. It is very important to determine the population parameters of pufferfish species to shed light on the studies to be carried out to restore the ecological balance in the Mediterranean ecosystem. This study will provide basic information that will be useful for fisheries scientists and managers in the Mediterranean Sea.
