This study aimed to isolate and identify the growth hormone (GH) mRNA gene in Tiger shovelnose catfish (Pseudoplatystoma fasciatum Linnaeus, 1766). The sample was isolated from the pituitary, the fish measuring 602 g and 43 cm body length; Total RNA was extracted using the Tri Reagent Kit, followed with cDNA synthesis. The success of the extraction was confirmed by quantification and PCR using the β-actin gene as an internal control. GH mRNA gene was isolated by RT-PCR method, with degenerated primers from seven catfish species sequence data in the NCBI gene bank. The single band from GH gene was cloned and sequenced. Total RNA quantification with a concentration of 227 ng/µL and purity of 1.821. The successful isolation of mRNA from the pituitary gland was confirmed by amplifying the β-actin gene generated at 300 bp. This isolation of the GH mRNA gene had a sequence length of 234 bp. Tiger shovelnose catfish GH gene consists of 17 amino acid residues. The GH gene of Tiger shovelnose catfish was close to that of striped catfish (P. hypophthalmus) and Indian catfish (Clarias batrachus) with almost similar homology value of 90.6 %. Partial GH gene from tiger shovelnose catfish can be used a molecular marker in revealing the role of growth hormone on fish development, fish biology, growth gene expression, selective breeding and other mechanisms related to the aquaculture.","PeriodicalId":36566,"journal":{"name":"Indonesian Aquaculture Journal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43396192","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The domestication process of this species has been started; however, its breeding program has not yet been successful. Therefore, this study aimed to examine the reproduction performance of intraspecific hybrids of blue swimming crab from Sorong (Papua) and Barru (South Sulawesi), Indonesia. P. pelagicus from Sorong has a bigger size, while the crab from Barru has a better reproduction performance, including fecundity and egg diameter. Hybridization was conducted between crabs from Sorong and Barru with different combinations of broodstock, namely: Barru female ><Barru male, (BF><BM); Barru female ><Sorong male (BF><SM); and Sorong female ><Barru male (SF><BM). The results showed no significant difference in the fecundity and egg diameter between the three hybridization trials. The number of successfully spawned broodstock from BF><BM, BF><SM, and SF><BM were 3, 3, and 2 broodstock, respectively. Meanwhile, the mean values of egg fecundity from BF><BM, BF><SM, and SF><BM were 117, 109, and 151 eggs/g BW, respectively. Furthermore, the mean values of broodstock fecundity per crab were 7,797 eggs, 10,103 eggs, and 10,605 eggs, while the mean values of egg diameter were 0.58 mm, 0.57 mm, and 0.62 mm, respectively. In conclusion, the intraspecific hybridization was successfully carried out between the Barru and Sorong crab populations showing no differences in the fecundity values and egg diameter between the three crosses.

Evaluation of the production performance of striped catfish larvae using live feed D. magna in both live and frozen compared with feeding Tubifex became the objective of this research activity. The experimental design used feed treatment with Tubifex (P1) as a control, live D. magna (P2), and frozen D. magna (P3) with four experimental replications for 15 days of rearing using a completely randomized design. Twelve aquariums with a water volume of 150 L were used in the experiment. Striped catfish larvae (1.5 cm TL), as many as 9 fish/L were stocked in each aerated aquarium. The amount of feed given was 15% of the weight of fish biomass with a frequency of 4 times a day and increased every day by 10% from the total feed of the first day. Results of the experiment showed different feeding significantly affected absolute length growth, total biomass, and feed conversion, with the best treatment being Tubifex (P1) with values of 0.6 ± 0.02 cm, 83.93 ± 5.99 g, and 1.31, respectively. The best growth rate of weight and length were obtained on larvae fed Tubifex (P1). The best protein efficiency and retention ratio resulted from frozen D. magna feed (P3) treatment of 12.45 and 7.11%, respectively.

This research aims to evaluate the resistance and gene expression of barramundi challenged by NNV. Two populations were used in this study, i.e., Australian, and Situbondo-originated barramundi populations. The immune-related gene expression levels in the liver, head of kidney, and spleen were observed at 48 and 96 hours after post-infection (hpi). Barramundi’s survival and blood parameters were evaluated post-NNV infection. The results showed that the highest survival was revealed in Situbondo’s barramundi (42.0±4.47%) compared to Australian barramundi (20.0±7.07%) and no mortality was observed in the control without NNV infection. The higher survival rate in barramundi from Situbondo was in line with the blood profile. The number of red blood cell from Situbondo barramundi post-NNV infection (ST) at 96 hpi was higher (P<0.05) than Australian barramundi post-NNV infection (AT). The number of white blood cell of ST at 48 hpi was higher (P<0.05) than AT, but started to decrease at 96 hpi in ST barramundi. The total white blood cell in AT barramundi increased from 48 to 192 hpi.

In March 2021, several orange clown fish at Batam Mariculture Development Center exhibited lethargic behavior with wart-like nodules on the fins suggesting a viral disease infection. This study aimed to detect the suspected viral disease agent from the clownfish and determine its genotype based on the major capsid protein gene. The fish tissues with wart-like nodules were collected and fixed in 96% ethanol. The DNA was extracted from the tissues and used as the template for the amplification of the major capsid protein (MCP) and myristylated membrane protein (MMP) genes using polymerase chain reaction (PCR). The nucleotide sequences of the PCR products were analyzed for their homology using the Basic Local Alignment Search Tool (BLAST). Multiple alignments of the amino acid sequence of MCP were performed using MEGA-X to determine the genotype. The PCR amplification produced the expected bands for detecting MCP, MMP and DNAPol genes. These results indicated the presence of Lymphocystis disease virus (LCDV), designated as LCDV-Oc-Btm. The sequencing of MCP and MMP genes produced the 1221 and 407 nucleotides, respectively. The BLAST analysis showed the highest identity was obtained with the species of LCDV-1 (LCDV-Sa strain) at 91.04 % and 88.19 % for MCP and MMP, respectively. The UPGMA phylogenic tree showed LCDV-Oc-Btm differs from the existing genotype and can be assigned as a new genotype.

In this study, the crayfish breed F3, which exhibits rapid growth and a favoured haplotype combination of the immune genes R, ALF, and crustin2, encoding the Toll-like receptor, anti-lipopolysaccharide factor, and antimicrobial peptide, respectively, were selected as parents to breed offspring (the selected group (SG)). The genotype, stress resistance, and disease resistance of crayfish in the SG and unselected group (USG) were compared. The results showed that the ratio of the favoured haplotype was higher in the SG crayfish than in the USG crayfish, leading to stronger stress and disease resistance. Compared to that of the USG crayfish, the mortality of the SG crayfish subjected to stress during eight days of transport and challenged with bacteria (Aeromonas hydrophila or Vibrio parahaemolyticus) or white spot syndrome virus were significantly reduced by 60% and 20%, respectively (p < 0.05). Based on these results, the stress- and disease-resistant SG crayfish were named the “Huachizhen-1” breed. Additionally, the ratio of the unfavoured homozygous genotypes of R, ALF, and crustin2 sharply decreased, whereas those of the heterozygous genotypes increased together with stress and disease resistance during crayfish maturation under natural conditions, indicating that the heterozygotes of these genes also exhibit strong stress and disease resistance.
