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

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

Parasite infections in aquaculture can trigger primary infections due to decreased fish immunity making it easier for other microorganisms, both bacteria and viruses, to enter the fish's body. This study aims to identify, calculate the prevalence and intensity of parasites that found in catfish ponds of the "Mino Ngremboko" fish farmers group in Grabag Village, Grabag District, Purworejo Regency. This study used the scraping method by reviewing the gills, mucus from the skin, fins and digestive tract onto a glass object which was then observed microscopically using a light microscope with a magnification of 10-40x. The parasites found were ectoparasites consisting of 6 species; Trichodina sp., Tetrahymena sp., Gyrodactylus sp., Epistylis sp., and Dactylogyrus sp. No parasites were found from the endoparasite and hematozoa groups. The highest prevalence was Dactylogyrus sp. with a prevalence rate of 54% and the lowest was Dinoflagella with a prevalence rate of 10%. The highest and lowest parasite intensities were Epistylis sp. (18,0 ind./infected fish) and Dactylogyrus sp. (2,8 ind./infected fish), respectively. It can be concluded that the level of parasitic infections in the fish farmer groups ponds was at the "common-usually” level based on William and Bunkley's prevalence criteria.Key words: Clarias sp., identification of Parasite, prevalence, intensity, Mino Ngremboko

Abstract

One disease that often attacts fish is a group of parasites or parasitic diseases, parasites are not only dangerous because they are related to their activities, but also trigger the emergence of other pathogenic organisms and cause infections. Therefore, it is necessary to take fish quarantine measures to prevent the spread of diseases carried out by fish quarantine centers. This study was conducted to determine the type of parasite that infested fish samples and determine the prevalence and intensity of fish samples. A total of 48 sample fish consisting of freshwater and seawater fish were analyzed in the laboratory of Balai Karantina Ikan, Pengendalian Mutu dan Keamanan Hasil Perikanan Surabaya II during December - January 2019, either directly or directly (ectoparasites and endoparasites). Parasitic identification was carried out visually and microscopically with an approach based on identification books. The types of parasites that we found during the study consisted of Argulus sp, Trichodina sp, Anisakis sp., Gnathostoma spinigerum, and Gnathostoma spinigerum. The highest prevalence in Scomber Scombrus with Anisakis sp. Amounting  to 77.8%, mean while, the lowest prevalence and the intensity is found in Thunnus sp. The prevalence and intensity of parasites are influenced by water quality and pollution.

Abstract

The purpose of this study was to determine the effect and optimal dose of addition of Moringa oleifera leaf extract on culture media to the growth and content of carotenoids of Dunaliella salina. The research method used was experimental with Completely Randomized Design (CRD) as the experimental design. The treatments used were different doses of Moringa leaf extract, namely A (100% walne media), B (75% Media walne + 25% Moringa leaf extract), C (50% Media walne + 50% Moringa leaf extract), D ( 25% Media walne + 75% Moringa leaf extract), E (100% Moringa leaf extract) with a dose of Moringa leaf extract that is 28 ml (100%) with repetitions 4 times. The results showed that the addition of Moringa oleifera leaf extract had a significantly different effect (P <0.05) on growth. Based on the density of Dunaliella salina showed the best treatment, namely at treatment B (75% walne + 25% Moringa extract). The best specific growth rate is found in treatment B (75% walne + 25% Moringa extract). The carotenoid content after treatment was not significantly different (P> 0.05) so that the carotenoid content in the control (treatment A) had the highest level of 1.39 µg / ml and the lowest was in treatment C of 0.19 µg / ml.
