Abstract

Salina is a high salinity tolerant hybrid tilapia seed of genetic improvement that can grow well in brackish water that has salinity more than 20ppt or even in marine water with salinity up to 32ppt through the utilization of character euryhaline tilapia. Salina has been oficially by the Ministry of Marine Affairs and Fisheries in March 2014 based on the Decree of the Minister of Marine Affairs and Fisheries of the Republic of Indonesia Number 22/KEPMEN-KP/2014 on the Release of Salina Tilapia with commercial name Salina (Saline Tolerance Indonesian Tilapia). This study aimed to identify the financial feasibility as well as internal and external Salina culture factors in order to formulate the development strategy of Salina tilapia culture. The method used was quantitative descriptive analysiswhich consists of a matrix Internal Factor Evaluation (IFE), External Factor Evaluation (EFE),Internal-External (IE), Strength-Weakness-Opportunities-Threats(SWOT), andAnalytic Hierarchy Process (AHP) as a decision-making methods. The instruments used in the financial analysis were BEP, NPV, IRR, Net B/C Ratio, and PP. Based on financial analysis, Salina culture was feasible. While the result of the calculation of IFE is 2.18 and EFE is 3.10, positioning the Salina cell II. The results of the AHP assessment stated that the strategic priority of the strategy was to conduct promotional and socialization activities to introduce Salina as well as to attract public interest and increase demand.

Abstract

Anguillid herpesvirus 1 (AngHV-1), a member of the Alloherpesviridae family, is known to cause high mortality in both wild and farmed eels. Notably, no cases of AngHV-1 infection in Indonesia until June 2023, when a significant mortality rate exceeding 75% among cultured glass eels was documented in Bogor, Indonesia. This study investigated the outbreak by collecting 30 diseased fish from multiple cultured tanks to examine clinical symptoms, histopathological changes, and viral presence through PCR targeting the viral DNA polymerase gene. Hemorrhagic lesions in the abdomen and anal regions were the primary clinical symptoms. Histopathological examination revealed hyperplasia, fusion, and epithelial lifting of the gill secondary lamellae. PCR, using 394 bp primer specific for AngHV-1, confirmed 100% infection among the collected samples, indicating rapid viral transmission within the rearing environment. Phylogenetic analysis of partial DNA polymerase amino acid sequences showed that Indonesian AngHV-1 isolate is genetically diverse and shares similarities with strains from China, Taiwan, Canada, and several European countries, suggesting the emergence of a novel strain. This study highlights the urgent need for enhanced biosecurity measures to curb AngHV-1 spread in the Indonesian eel aquaculture sector.

Abstract

This study focuses on the morphology of the Nile tilapia local strain (Salina), a salinity-tolerant tilapia hybrid strain developed by crossbreeding between female Nile tilapia Red NIFI with male Nile tilapia Sultana. The research aimed to analyse the morphometric characteristics of the Salina strain to understand species adaptation to suboptimal environmental conditions compared with the parental groups. A total of 60 Nile tilapia fish, ten female and ten male samples from each strain (Salina, Sultana, and red NIFI), were measured for their total length (TL), standard length (SL), head length (HL), body width (WID), dorsal fin length (DL), caudal fin length (CL), pectoral fin length (PL), caudal peduncle depth (CPD), eye diameter (ED), snout length (SNL), and body weight (BW). Each measurement parameter was then normalized by comparing it with the standard length (SL). The data were analysed using MS Excel 2019 and R v4.5.1 for all statistical analysis including MANOVA, Canonical Variance Analysis, Principal Component Analysis, and Hierarchical Clustering Analysis. Condition factor (K) and length-weight relationship (LWR) were calculated to investigate growth conditions and allometric growth patterns, respectively. Based on the findings, the six tilapia populations exhibit overlapping morphological traits, except for female Salina with slight differences in morphological variations. This implies its potential unique traits acquired from crossbreeding between two different strains. Meanwhile, male Salina showed morphometric traits closely aligned with its male parent, the Sultana strain. The condition factor across all populations indicates favourable growth conditions, although the negative allometric growth pattern suggests that length increases more rapidly than body weight, implying an adaptive trade-off in suboptimal environments.
