Abstract. The objective of present study was to evaluate the possibility of  papaya’s latex (Carica papaya) as anti stress or larvaside for tiger shrimp (Panaeus monodon) post larvae Pl 14-30 during transportation. The tiger shrimp post larvae was collected from BBAP Ujung Batee, Aceh Besar on September, 2012. Reseach method used the completely random design with two factors, density of post larvae with three treatments (1000; 1500 dan 2000 ind/l) and concentration of papaya’s latex with four treatments (0; 100; 200 dan 300 ppm) and three replications for each treatments. The effect of papaya’s latex on tiger shrimp post larvae was observed by calculating the percentage of post larvae’s survival rate. The calculation was only done after twelve hours of transportation, due to the everage of survival rate percentage of post larvae on all levels of density was less than 50%.  The ANOVA test showed that  the density and the concentration factors gave significance effect on survival rate of tiger shrimp post larvae (P0,05). The results showed that survival rate of tiger shrimp post larvae (PL 14-30) were decreased with increasing of larvae density and concentration of papaya’s latex.  However, Duncan’s test showed that the highest survival rate was obtained at 1.000 ind/l  and 0 ppm of papaya’s latex. Hence, the effect of papaya’s latex concentration treatments in this study was larvaside on tiger shrimp post larvae.Key words: Closed transportation system, dissolved oxygen, enzyme papain, tiger shrimp post larvae.

Abstract

Tilapia (Oreochromis niloticus, Linnaeus, 1758) is a dominant commodity in the Indonesian freshwater fishery industry, and its growth relies on feed. Pellet are feed that is processed through a factory mechanism or human intervention, based on the cultivators needs. Therefore, the purpose of this study was to determine the effect of pelleted feed with varying protein content on growth and survival of tilapia (Oreochromis niloticus) fry. This was conducted from April 2022 to June 2022, in Tasiwalie Village, Suppa District, Pinrang Regency. The test animals used were tilapia aged 30 days, and feed include omega-3, Hi-Pro-vite 781, and Prima feed 500 grams each. An experimental method was employed using a Completely Randomized Design (CRD) with three treatment and replications, where treatment A, B, and C were Prima Feed (39 41%), Hi-Pro Vite (protein 31 33%), and Omega feed (protein 13 16%), respectively. Artificial feed was given at a dose of 5%/body weight 3 times a day. Also, water quality management was carried out by measuring temperature, dissolved oxygen, pH, and ammonia. The results showed that different feed affected protein retention with the highest average value of 43.23%, the highest average fat retention of 48.56%, absolute weight growth of 1.58 g, absolute length growth of 2.33 cm, daily specific weight growth rate of 3.75%, daily specific length growth rate of 5.56%, and feed utilization efficiency 70.60%. Furthermore, the best growth was obtained in treatment A, involving Prime Feed from 39 41%. This study showed that the percentage of protein had a significant effect on growth and survival of tilapia. Therefore, the feed industry is needed to formulate requirements based on tilapia fish, to increase production.Keywords:TilapiaFeedGrowthSurvival

Abstract

Post-larval snakehead (Channa striata) can be fed on live silkworms (Tubifex sp.), artificial feed and a combination of both as a source of nutrients. The availability of live silkworms depends on the yield in nature. Meanwhile, dried silkworms are available in the market. Therefore, the study to evaluate feeding combinations of dried silkworms and artificial feed for the rearing of post-larvae snakehead was conducted from October to December 2020 in Serang District, Indonesia. The treatments were combinations of dried silkworm and artificial feed at a ratio of 100:0%, 75:25%, 50:50%, 25:75%, and 0:100%, respectively. After being adapted to experimental conditions, post-larvae of snakehead (0.40±0.02 g) were randomly stocked in 15 happas of 50x70x75 cm in dimension size each at a rate of 25 post-larvae and fed on tested diet according to the treatments at 5% of biomass a day, divided into three times for 40 days of experimental periods. The post-larvae of snakehead performed the best growth at the contribution of dried silkworm at 100 – 25%, the best feed conversion and protein efficiency ratio at 100 – 50% and 50%, respectively and the best survival at 50 – 0%. It could be suggested that feeding dried silkworm and artificial feed at a 50:50 ratio, respectively, during post-larvae snakehead rearing.Keywords:Channa striata Feeding combination Nutrient sourcesPost-larvae rearing

Abstract

Giant freshwater prawn is a native Indonesian freshwater prawn, which has the largest body size among other freshwater prawn. Efforts to increase the production of giant prawns can be done by genetic improvement of the parent. The main basis for conventional genetic improvement of giant freshwater prawns is availability of morphological variation information. This study is to determine the morphological variations of the giant prawn broodstock of Siratu, GIMacro, Mahakam, and Bengawan Solo populations which are cultured in Unit Kerja Budidaya Air Payau Balai Budidaya Udang Galah (UKBAP BBUG) Samas. Through this research it is expected to determine the broodstock with a profitable character that is able to produce hybrids with profitable characters as well. Baseline morphometrics were observed from the ratio of cephalothorax: abdomen length, ratio of carapace: rostrum length and ratio of carapace: abdomen length. Morphological variations were observed using 58 characters which included morphometric, meristic and morphological characters. The results showed the largest ratio of cephalothorax and abdomen average length owned by Bengawan Solo population, while the largest ratio of carapace and abdominal average length owned by Mahakam. The highest morphological variation is owned by Mahakam with 52% similarity. The lowest morphological variation is owned by GIMacro and Siratu populations with 80% similarity. The giant prawn broodstock which is expected to produce hybrid with profitable character is the broodstock from Bengawan Solo population.Keywords: Giant freshwater prawn, Morphological variation, SiratuGIMacro, Mahakam, Begawan Solo ABSTRAKUdang galah merupakan udang air tawar asli Indonesia, yang memiliki ukuran tubuh terbesar di antara udang air tawar lainnya.

Abstract

The Brachionus plicatilis species complex comprises a group of rotifers commonly found in marine and brackish water environments worldwide. This group has garnered substantial attention due to its ecological significance and its utility in aquaculture research. Notably, the B. plicatilis sp. complex is renowned for its remarkable genetic diversity, which has been extensively investigated through molecular and taxonomic studies. Various genetic markers, including ribosomal DNA and mitochondrial DNA, have been employed to identify several distinct genetic lineages within the B. plicatilis sp. complex. Understanding the taxonomy and phylogenetic relationships within the B. plicatilis sp. complex holds significant implications for its application in aquaculture and ecotoxicology research. In this study, we conducted an analysis of the mitochondrial DNA cytochrome c oxidase subunit I (COI) gene using a dataset of 305 sequences, including four Indonesian rotifers belonging to the B. plicatilis sp. complex. These rotifers were obtained from Sulawesi Island (MNBO and MNSL), Bali Island (AY785226), and Sumatra Island (LMPG). Our primary objective was to determine their phylogenetic positions relative to molecular data available in the GenBank database. We calculated genetic distances among these rotifers using the Tamura Nei model. The results of Maximum Likelihood tree analyses revealed distinct clustering patterns among the Indonesian rotifers. Those originating from Sulawesi Island (MNBO and MNSL) and Bali Island (AY785226) formed the SS1 group (B. ratundiformis), whereas those from Sumatra Island (LMPG) comprised the SM2 group (B. koreanus). This study underscores the importance of molecular phylogenetic analysis in advancing our comprehension of the diversity and evolutionary relationships within the B. plicatilis sp. Complex.Keywords:PhylogenyRotiferaBrachionus plicatilisSpecies complexIndonesia

Abstract

Catfish farming is one of the businesses that is very much in demand by the community, because it can improve the community's economy. However, not all catfish farming businesses can produce maximum results. This can be caused by several factors, both from feed, management and water quality. Decrease in water quality can be caused by feces and fish feed residue. Poor water quality can cause the growth process, physiology and level of fish behavior to be disturbed. Efforts that can be done is to use aquatic plants as phytoremediation. The plants used in this study were Azolla sp, Eichhornia crassipes, Lemna sp, Ipomoea aquatic. The design used in this study was a completely randomized design with 4 treatments and 3 replications. The parameters observed in this study were ammonia levels, pH, and plant population. The results showed that Eichhornia crassipes and Lemna sp were able to reduce ammonia levels in catfish cultured water by 0.01 mg/l at the end of the study.Keywords:AmmoniaWater plantsCatfish
