Abstract

Botia fish (clown loach) growth is relatively slow, taking 4-5 months to reach marketable size (2 inch) and 3 years to achieve initial gonad maturation in female and 1 year in male fish. Environmental degradation and overfishing are factors triggering the production of newly potential broodstock. This study aimed to observe the growth response of potential broodstock through rearing technique with and without shelter. Fish were kept inside the aquaria sized 80x40x30 cm with 20 cm water height on the recirculation system. Fish used for shelter treatment were: Total length ± 7.7 cm, height ± 2.09 cm, and weight ± 7.33 g; for no shelter treatment were: Total length ± 6.7 cm, height ± 1.88 cm, and weight ± 4.59 g. Fish were stocked 10 fish / aquarium and fed 3 times / day by at satiation method. Parameters observed were total length, height and weight improvement also water quality. The results showed that growth and feed efficiency had better value when reared with shelter than without shelter.Keyword: Grow-out, Chromobotia macracanthus, shelter

Abstract

Crab (Scylla serrata) is a commodity that has high prospects for cultivation. Cultivation in Indonesia has not been intensive and densely spread low due to the threat of crab deaths due to cannibalism. The purpose of this study was to determine the comparison of the growth of male and female crabs in the recirculation system to increase the productivity of mangrove crab. The research was conducted from November 2019 to June 2020 at the Aquaculture Laboratory, Faculty of Fisheries and Marine Sciences Satya Negara University of Indonesia and blood tests were conducted at the Center for Freshwater Aquaculture Fisheries- Bogor. The experiment used a Complete Randomized Design (CRD) consisting of three treatments and five replicate each. The treatments consisted of: A: male crab; B: female crab; C: Control. The number of seeds that used in this study were 5 for each treatment with five replications and density of 5 crab per maintenance container (gallon). The feed provided were fish feed selar Atule mate which was cut into small pieces. The selar fish came from Muara Angke, North Jakarta. Feeds were given with frequency 4 times a day. The results showed that the growth of male and female mangrove crab gave the best production performance in the treatment of female maintenance containers with survival rate of 53.33%, absolute growth rate of 3.76 g, and carapac width of 3.44 mm.Keywords: crab (Scylla serrata.), growth, recirculation system

Abstract

The study of biodiversity is important in looking at the current condition of an aquatic environment. The purpose of this study is to examine the biodiversity of the fauna in the Progo River in determining the level of fish diversity and the status of fish resources in the Progo river by using a Geographical Information System (GIS). The sampling method was carried out by purposive sampling consisting of 17 stations. The data taken includes coordinate points, the diversity index (H '), evenness index (E), dominance index (D), and relative abundance (Kr), as well as making a map of the distribution of progo river fish using Arcgis software version 10.5. The results showed that the diversity index value (H ') was moderate to high with a value range of 2.24 to 3.83, with a catch composition consisting of 23 species and 11 families. The evenness index value (E) of the progo river ranges from 0.71 to 1.21. Based on this value, the Progo River has an evenness value between species that is relatively even or the number of individuals of each species is relatively the same. Progo river dominance index value ranges from 0.002-0.008, that is, no fish species dominates. The highest relative abundance (Kr) was balar fish (Barbonymus balleroides) = 0.12%, melem fish (Osteochilus vittatus) = 0.11%, uceng fish (Nemacheilus fasciatus) 0.09%, tilapia fish (Oreochromis niloticus) 0 , 08%, while the lowest was kekel fish (Glyptothorax platypogon) and sepat fish (Trichopodus trichopterus) with a value of 0.01%. The results of the analysis of the distribution of fish in the Progo river show that the fish are widely distributed in the river area which has deep and calm water characteristics, this is indicated by the number of catches at each research station.Keywords: Biodiversity, Progo River, Geographical Information System (GIS)

Abstract

Baung fish is one of the local fish in West Kalimantan which has high economic value. One of the problems that arise in the maintenance of baung fish larvae is the low survival and growth rate, the most strategic solution is to determine the right type of feed according to the feeding habits of the baung fish larvae. The purpose of this study was to obtain the type of natural food that was most effective in rearing the larvae of fish. The research design used a completely randomized design (CRD) with 4 treatments and 3 repetitions. Treatment types of natural feed used in this study were Artemia (A), Water Fleas (B), Silkworms (C) and Pellet Flour (D), and arranged randomly. The results of the research through analysis of variance (Anova) show that all treatments can have a significant effect on the absolute length growth rate variable and the survival rate variable. Based on Tukey's further test, the treatment that had the best effect on the growth rate of absolute length was treatment C, namely 9.20 ± cm, while the treatment with the highest effect on survival rate was treatment A which was 98.8Keywords: Natural Feed, Baung Fish, Growth, Survival

Abstract

Baung fish is one type of local fish that has a slow growth. One of the efforts to increase the growth of baung fish can be done by using probiotics. This study aimed to determine the optimum dose of probiotic addition for the baung fish rearing. The experiment used a completely randomized design (CRD) with four treatments, three replications, and one control. The probiotic doses: 2 ml/kg of feed (A), 4 ml/kg of feed (B), 6 ml/kg of feed (C), 8 ml/kg of feed (D) and 0 ml/kg of feed (control) were used as treatment. The commercial feed was given ad satiation with a frequency of feeding three times a day. Observations were made for two months. The results showed that the D treatment of 8 ml/kg of feed gave the best absolute weight growth and feed conversion ratio. While, the baung fish survival rate was not significantly different on all treatments.Keywords: Baung fish, growth, probiotics

Abstract

Daun pepaya merupakan bahan alami yang sering dimanfaatkan dibidang perikanan air tawar khususnya sebagai pakan tambahan, karena memiliki kandungan enzim yang dibutuhkan oleh ikan. Penelitian ini bertujuan untuk menganalisis pengaruh penambahan serbuk daun pepaya pada pakan untuk meningkatkan pertumbuhan ikan lele (Clarias sp). Pakan yang digunakan pada penelitian ini yaitu pakan komersil dengan kandungan protein 30% yang ditambahkan serbuk daun pepaya. Serbuk daun pepaya didapatkan dari daun pepaya yang dikeringkan terlebih dahulu sampai benar-benar kering. Setelah kering daun pepaya dihaluskan dengan menggunakan blender. Penelitian dilakukan secara eksperimental menggunakan Rancangan Acak Lengkap (RAL), dengan 4 perlakuan dan 3 ulangan. Perlakuan 1 (P1) sebagai kontrol (tanpa pemberian serbuk daun pepaya), P2 (pakan dengan serbuk daun pepaya 2 %), P3 (Pakan dengan serbuk daun pepaya 3,5 %), P4 (pakan dengan serbuk daun pepaya 4,2 %). Parameter pertumbuhan merupakan parameter utama yang diamati pada penelitian ini. Analisis data menggunakan ANOVA untuk meliihat perbedaan pengaruh dari masing masing perlakuan dengan selang kepercayaan 95% (p>0.05). Hasil penelitian menunjukan bahwa penambahan serbuk daun pepaya memberikan pengaruh nyata terhadap laju pertumbuhan panjang dan berat (p>0.05), dimana perlakuan terbaik terdapat pada P3 dengan pertumbuahan panjang sebesar 2,69 g dan 3,51 cm, berat dan panjang spesifik 3,89 g dan 5,89 cm, serta FCR 0,517.Kata kunci: pertumbuhan, serbuk, daun papaya

Abstract

Utilisation of plant proteins to replace fish meal in shrimp feeds has become an important consideration because fish meal is becoming more expensive due to increasing demand worldwide. The potential use of palm kernel meal (PKM) in this study to substitute fish meal in the Pacific white shrimp (Litopenaeus vannamei) diets was evaluated by conducting a 90-day feeding trial. Shrimp juveniles with an initial average weight of 0.5 g, protein content of 10.74±0.70% were randomly distributed into five treatments in triplicates. Four isonitrogenous (approximately 35% protein) diets were formulated to contain 0% (D0), 25% (D25), 50% (D50) and 75% (D75) of PKM replacement and a commercial feed served as control treatment (Control). Results from this study revealed that shrimps fed D25 were comparable with those fed with Control as there was no significant difference (p>0.05) in weight gain and specific growth rate (SGR) between the groups. However, PKM inclusions above 50% showed detrimental effects on the growth performance. The highest total protein percent was observed in shrimp tissues fed with D25 (67.59±0.87%) and D75 showed the lowest protein among the treatments (57.4±0.63%) (p<0.05). Total lipid content was observed high in shrimps fed with Control (4.33±2.96%) and decreased with PKM replacement levels. The highest carbohydrate was found in shrimps fed with D75 (16.75±0.04%) and the lowest was found in shrimps fed with D25 (14.67±0.07%). When PKM is utilised to replace FM, a limit of 25% level should be recommended.
