Background: Mystacoleucus padangensis living in Lake Singkarak, Indonesia, has high potential market demand but is threatened by overfishing and has not been successfully cultured. This study describes the first broodstock development, induced breeding, and larval rearing of M. padangensis. Methods: A total of 1,000 female and 1,000 male broodfish were collected from the wild and reared in two concrete ponds (128 m2) at the Centre for Biodiversity Conservation, P.T. Semen Padang, Indonesia. The broodfish were fed commercial feed to satiation at 09:00 and 17:00 h. The females (average weight 7.56 ± 0.85 g) and males (4.86 ± 1.20 g) were selected at a ratio of 1:4 (female:male), and gonad maturation was induced with a single dose of GnRH analogue (Ovaprim) of 0.1 ml/fish. At 16 h after hormone injection, eggs were collected individually into a plastic vessel. Spermatozoa were collected with sterile syringes. Eggs were fertilized using the "dry" method, and 0.5 ml samples (equal to 100 eggs) were taken. The eggs were incubated in a plastic strainer with a water volume of 1.57 litres and placed in a tarpaulin pond with a volume of 150.72 litres. Results: The overall hatching rate was 78.93 ± 4.13%. The newly hatched larvae were 3900.81 µm long, with a yolk sac of 82881.480 µm2. The mouth opened at 72 days post hatching (DPH) with a gape measuring approximately 61.880 µm. The protocol of larval feeding started with artificial feed, followed by Artemia nauplii up to 30 DPH. Weaning of larvae started at 4 DPH. Larvae started metamorphosis by 15 DPH and ended by 22 DPH when the larvae reached 7430.27 µm. Larval rearing resulted in an average survival rate of 28.4 ± 3.04%. Conclusions: Its successful spawning induction and high larval hatching and survival rates make M. padangensis an excellent aquaculture candidate.

“…Compared with wild sh, farmed sh are affected by more stressors such as con nement, long-distance transportation, new breeding environment, limited breeding space, and an increase in pathogenic microorganisms (Macaulay et al 2021). In aquaculture, the malignant stress can disrupt the overall balance of farmed sh, causing the transfer of energy matrix to cope with the increased energy demand related to stress, thereby affecting the normal growth, reproduction, immunity and other important life activities, and can even lead to large-scale death in extreme cases (Balasch and Tort 2019; Kumar et al 2022). Therefore, it is necessary to avoid the occurrence of malignant stress during the breeding process.…”

Reducing the escape response of fish during the aquaculture has important economic value and ecological safety significance. This study takes the common strain black carp (Cyprinus carpio var. baisenensis), which is known for its low-escape response, as the main research object. Through a simulated flood experiment, the common strain black carps were divided into the low-escape (BL) group and the high-escape (BH) group. Multi-omics techniques:transcriptome sequencing, LS-MS/MS detection, and 16s sequencing were used to analyze the differences in brain gene transcription levels, liver metabolites, and intestinal microbiota composition between the two groups. In addition, in order to reduce false positives generated by transcriptome experiments, Jian carps (Cyprinus carpio var. Jian) were also grouped into the low-escape (JL) group and the high-escape (JH) group and subjected to transcriptome analysis. According to the differentially expressed genes (DEGs) analysis, 18 DEGs were obtained from both the common strain black carp and Jian carp. Except for the MAP6 gene, which was significantly highly expressed, the remaining 17 genes showed significantly low expression in the BL group, which were almost related to signal transduction, and brain tissue and neuronal development. The results of KEGG signaling pathway annotation, KOG functional annotation, and topGO enrichment analysis showed that there were significant differences in signal transduction between the BL and BH groups, especially in the gama aminobutyric acid (GABA) signaling pathway. The detection of liver metabolites showed that there were differences in tryptophan metabolism between the BL and BH groups of the common strain black carp, with higher tryptophan content in the liver of the BL group fish. This study suggests that the brain activity and development of low-escape fish may be lower than that of high-escape fish. Meanwhile, differences in the brain's GABA signaling pathway and the liver's tryptophan metabolismmay also affect fish's escape response. This study accumulates experimental foundation of fish escape response, and provides a new insight into breeding low-escape fish and developing novel strategies to reduce escape responses during aquaculture.
