pH is one of the important water quality parameters in aquaculture. This study aimed to observe the growth performance and survival rate of common carp (Cyprinus carpio) Rajadanu strain reared in culture media with different pH levels. Fish (length: 3.60 ± 0.18 cm; weight: 1.68 ± 0.18 g) were stocked in nine aquariums (40 cm x 40 cm x 30 cm) for 10 days with a stocking density of 25 fish per aquarium. The treatments used were (A) pH 4-5, (B) pH 5-6, and (C) pH 6-7, with three replications. A commercial feed containing 28% protein was given daily and as much as 3% of the total biomass. The observed data were analyzed using variance analysis (ANOVA), followed by Duncan test. The results showed that the pH treatments did not affect the growth (length and weight) and survival rate of common carp Rajadanu strain (P>0.05). The best growth was achieved by the fish group reared in water with a pH range of 6-7 (length = 0.38 cm; weight = 0.17 g). The highest survival was attained by the fish group reared in water with a pH range of 5-6 (90.66%).

To counter disease problems caused by vibriosis in shrimp hatchery, this recent study used three different probiotics to be tested on tiger shrimp (Penaeus monodon) postlarvae. The study arranged four treatments as follows: A: a combination of three liquid-form probiotics Brevibacillus laterosporus BT951, Bacillus subtilis BM12, and B. licheniformis BM58; B: a combination of three powder-form probiotics Brevibacillus laterosporus BT951, Bacillus subtilis BM12, and B. licheniformis BM58; C: a commercial powder probiotic containing Bacillus subtilis; and D: control (without probiotic), each treatment with three replications. This study was set up in a completely randomized design experiment using twelve fiberglass tanks filled with 750 L sterile sea water and stocked with 30,000 nauplii in the Awarange shrimp hatchery of the Research Institute for Brackishwater Aquaculture and Fisheries Extension Installation in Barru. Variables observed in this study were the survival rate of the shrimp postlarvae at the end of the experiment, total vibrio count (TBV) and total plate count of common bacteria (TPC) in the culture water. The results showed that the survival rate of tiger shrimp applied either in liquid (A: 61.5±4.7%) or powder form (B: 48.6±6.8%), and control (without probiotic) (D: 51.2±4.4%) were not significantly different (P>0.05). However, survival rates in these three treatments differed (P<0.05) with that of the commercial probiotic (C: 21.7±9.9%). TBV/TPC ratio in the tank waters treated with the commercial probiotic (2.26-37.52%) was much higher than that of the liquid form probiotic (0.86-1.98%), powder form probiotic (1.25-8.37%), and control (1.93-2.84%). Ammonia-nitrogen in treatment C (1.462-2.989 mg/L) was relatively higher than that of in treatment A (1.595-2.435 mg/L), treatment B (1.644-2.115 mg/L), and treatment D (1.051-1.858 mg/L).

Betta ornamental fish of marble strain is a strain which is prefered by the hobbyists, because of its unique color, expensive price, and difficult to obtain the fish color strains. Therefore strain marble betta fish is still dominant for export quality for national and international contests. The aim of this study was to observe the growth and color performance of the crossedbreed marble strains of wild betta, Betta imbellis crossed with Betta splendens. The hybrids of B. imbellis (f) x B. splendens (m) (D) had a specific length and weight rate, (1,113 ± 0.04%/day; 2,531 ± 0.14%/day; 26.61 ± 2.02 mm) which was better than that of the hybrids B. imbellis (m) x B. splendens (f) (C) (1,099 ± 0.02%/day; 2,244 ± 0.13%/day; 25.97 ± 1.33 mm; and 0.0027 ± 0.0003 mm). However, the survival rate of the C hybrids (42.19 ± 11.42%) was higher than those of D (33.67%-17.08%). Based on the obtained results of the color identification the hybrids had as many as 15 characters of color, homozygous strains of marble which became the target of as much as 1%.

The aim of this study was to investigate the growth characteristics of microalgae strains isolated from Kendari Bay and the Wanggu River estuary, Indonesia. The growth of the isolates, denoted as Kb1-2, Kb1-3, Kb1-5, and Kb2-6, were evaluated under controlled conditions. A batch culture experiment of these strains except Kb2-6 was conducted for 15 days under salinity levels of 20, 25, 30 and 35 gL-1. Tetraselmis chui, Tisochrysis lutea and Chaetocero sneogracile were also culture and used as the growth references. Cell density was measured every day and cell size was measured from 50 live cells during the logarithmic phase. The cell sizes of three of the four Indonesian microalgae ranged from 1.2-11.8 µm, considered suitable for shrimp larvae. The Indonesian strains started the logarithmic phase of growth at all salinities tested from day 0 to day 3 after inoculation except for Kb1-3 that started the phase after a 3-day lag. Increased cell density over the culture period and division rate of Indonesian microalgae during the logarithmic phase of growth were similar at all salinities tested and similar to T. chui, Ti. lutea and C. neogracile. However, the final biomasses after 15 days of culture of all microalgal strains were affected by culture salinities tested. Indonesian microalgal strains showed similar dry weight and ash free dry weight to smaller-cell strains, Ti. lutea and C. neogracile. Indonesian strains (other than Kb2-6) are suggested as suitable live food candidates for mass culture in shrimp hatcheries based on their cell size, ability to survive long culture periods, and wide salinity tolerance.

This study was aimed to evaluate different types and combinations of live foods in relation to the survivability of newly hatched Lysmata vittata and Lysmata intermedia larvae. The experiment consisted of three trials (different species, combinations, and densities of live foods) arranged in a completely randomized design. The first and second trials were subjected to L. vittata with three treatments for each trial (1A, 1B, 1C for trial-1; 1D, 1E, 1F for trial-2). The third trial consisted of two treatments (2A and 2B) tested on L. intermedia. Each treatment had three replicates. The results showed that the survival rates were low in all treatments. However, each treatment showed a significant effect (P<0.05) on the average survival rate of L. vittata and L. intermedia larvae. In the first trial, treatment 1C was the only one that had survived larvae after day 35 with 4.44% of final average survival rate (FASR). Four of the larvae reached the post-larval stage. In the second trial, treatment 1F showed a better condition than the other treatments with 5.56% FASR. Nevertheless, no larvae in the second trial had transformed to post-larval stage before the experiment ended at day 46. In the third trial, no larvae survived to reach the post-larval stage. In spite of this, treatment 2B had better daily average survival rate (DASR) than treatment 2A. This research concludes that the use of copepods as live food at an early larval stage and Artemia at a later stage is relatively more effective to improve the survival rate of peppermint shrimp larvae.

Selective breeding to improve growth trait in striped catfish (Pangasianodon hypophthalmus) need genetic performance data. This study was carried out to evaluate genetic performance of different generations of the striped catfish population derived from selective breeding. Fifty fish of each population from four generations selected striped catfish was analyzed using five microsatellite loci (Pg-1, Pg-2, Pg-3, Pg-13, and Pg-14). Microsatellite allele data were analyzed using Microsoft Excel, Arlequin, and Fstat software. A neighborhood joining dendrogram was constructed based on Nei’s distance (Da) matrix with 1,000 bootstrap replications using MEGA7 software. The result showed that totally 31.5 exist, ranged from 4-7. Number of allele was ranged from 5.0 to 5.2, and polymorphic data was from 0.45-0.60. There were some exception, such as the allele of the loci Pg-2—194 bp, Pg-13—227 bp, Pg-13—229 bp, and Pg-14—279 bp; their gene frequencies were increased by generation. Further analyses indicated that most genetic variations arise from individuals within populations (approximately 57.10%). The founder generation closely related to G-0 generation. Likewise, G-1 generation closely related to G-2 generation. This result indicated that selection activity had a very significant impact on the genetic improvement of the selected population.

Populations of spiny lobsters worldwide are threatened by overfishing, while its supply from aquaculture is currently insufficient to meet the market demand. This current study investigated the genetic structure of two economically important spiny lobsters, P. homarus and P. ornatus sourced from the Indian Ocean and South China Sea. Fragments of the cytochrome oxidase subunit-I (COI) gene of the mitochondrial DNA of 71 P. homarus and 42 P. ornatus collected from 6 and 5 fish landing sites in Indonesia, respectively, were sequenced. Homologous sequences from the Indian Ocean and South China Sea available at GenBank were included in the analysis. No genetic differences were observed in P. ornatus populations from the two geographic regions (xST = -0.005) while a diminutive difference was found in the populations of P. homarus (xST = -0.002 and 0.009). These results, combined with a negative Tajima’s D estimates, points to a deficit of nucleotide variation relative to the expectations from the mutation/drift equilibrium. Reconstruction of the phylogeny of P. homarus demonstrates that all Indonesian samples of P. homarus are grouped in one cluster and share the common cluster with GenBank data originated from Taiwan, Vietnam, India, Sri Lanka, Oman, and Iran. The phylogeny of P. ornatus indicates that there are two separated lineages existing in Indonesia.

The farming industry of the African catfish (Clarias gariepinus) in Indonesia is affected by a high feed cost during the grow-out phase resulting in low economic return. Selective breeding to produce new strains with low maintenance requirements is one of the potential solutions to overcome the problem. The present study aimed to identify and study the performance of the base population of African catfish treated with feed low in dietary protein during the grow-out phase. Out of 100 broodstock pairs, 96 pairs had produced successful hatching. Approximately 1,000 larvae from each pair were reared separately to reach seven-week-old juveniles. Then, 50 individuals from each pair were selected to form the base population. The base population was reared for four months and fed with commercial feed containing 12% crude protein resulting in final mean body weight of 82.04 ± 34.66 g, a specific growth rate of 2.02%/day, a feed conversion ratio of 4.23, and survival rate of 25.15%. At the end of the grow-out phase, the size variation among treated fish was relatively high (variation coefficient of 42.31%). The subsequent individual selection stage had identified that 325 individuals (equal to 26.93% of the total population) had the best performances with a mean body weight of 128.80 ± 22.80 g, selection differential of 46.80 g, and selection intensity of 1.35. These results suggested the potency of the selected base population be used in the forming of the next generation.

A four months feeding trial was conducted to evaluate the effects of two maturation diets containing either fishmeal (FM) or squid liver meal (SLM) as the major protein source on growth, gonadosomatic index and gonadal bio-chemical profiles of golden spotted rabbitfish, Siganus guttatus. The two tested diets were formulated to be iso-nitrogenous (40%) and iso-lipidic (14%) and supplemented with several micronutrients specifically for gonadal development. The initial weight of golden spotted rabbitfish used were 352.6 ± 45.0 g and stocked into four of 2 m x 2 m x 2.5 m net cages with 25 fish per cage. The test diets were fed to the stocks twice a day. After four months feeding, the weight gains (WG) of broodstock fed the two diets were nearly similar in which FM had WG of 40.1 ± 2.2% and 42.8 ± 2.0% for SLM. The GSI of male fed SLM diet was similar to that of fed with FM. However, the GSI of female fed FM was 5.6 ± 0.1% significantly lower (P<0.05) than SLM which was 11.4 ± 0.5%. Furthermore, total amino acid (TAA) in spermatocyte was significantly (P<0.05) influenced by dietary SLM indicated by its higher TAA (62.4%) compared to TAA content of FM group (46.1%). Similarly, the TAA content in oocyte was significantly (P<0.05) improved when fed SLM. The dietary SLM did not affect the TAA content in the fillet of rabbitfish demonstrated by the similarity of the fillet TAA content in the two groups which was 55.6% for FM and 54.1% for SLM. Dietary SLM enhanced GSI of female broodstocks and profile of amino acid in the gonad of golden spotted rabbitfish, Siganus guttatus.

The experiment was conducted to evaluate the effect of vitamin E on the gonad development of sandfish, Holothuria scabra. Four experimental diets were formulated to contain different levels of vitamin E, i.e. 0, 150, 300, and 450 mg/kg diet. Dry diets were prepared at the same protein level (14%). The experiment was arranged in a completely randomized design with four treatments and three replicates. Before the experiment started, the internal organs of broodstock were removed (evisceration) by injecting KCl 1 N reagent into their body, and the gonads were observed to determine the sex of each broodstock. Mean total length and body weight of broodstock after the internal organ removal were 10.95 ± 0.37 cm and 61.12 ± 2.28 g, respectively. Three broodstock (one male and two females) were allocated into each plastic bucket with a volume of 150 L. Each plastic bucket was equipped with aeration and flow-through water system. Broodstock fed with experimental diet once daily at 3% of total biomass for 90 days. The results showed that vitamin E has significant effects on percentage of gonad maturation stages and gonad somatic index (GSI) (P<0.05). Vitamin E at 300 mg/kg diet was the best for gonad maturation of sandfish broodstock. Furthermore, 55.5% and 11.1% of broodstock fed a diet containing 300 mg vitamin E/kg diet reached gonad maturity stage-III and stage-IV, respectively, with GSI of 12.21%.
