Abstract

Fish cultivation business is one of the very promising business with the increasingly cheap demand of fishery products in the community. So is the case with the cultivation of Tilapia fish. Aquaculture is not spared from various obstacles and problems that often hamper fish farming is the occurrence of disease attacks. Tilapia fish Who was attacked The disease starts with by showing signs of behavioral changes. In addition to the behavior, tilapia also experience a change in color that looks very clear difference compared to fish that are still healthy. Calculation of condition factors, from the three sampling sites average fish is in poor condition indicating that most of fish in pond cultivation have decreased condition that reach 60-90%, caused by disease / phatogen factor or environmental factor not good.The results of the laboratory analysis found six (6) parasites that infect tilapia: Dactyloyrus sp, Gyrodactylus spp, Tricodina sp, Vortycella sp, Oodinium sp, and Saprolegnia sp. Water quality is less good in the cultivation are resulted in the decreased condition of fish and support well the development of various types of parasites.

Abstract

This study aims to determine the diversity of demersal fish and feeding habits and food habits of demersal fish found in the lower reaches of the Yeh Sungi River. This research was carried out in the lower reaches of the Yeh Sungi River, Tabanan, Bali. This research began on April 17, 2016 until May 1, 2016. The research method used is descriptive exploratory method, namely by conducting a series of sampling activities of demersal fish species to identify the diversity of species and behavior (feding habit) of each type of demersal fish, as well as the food habit of each type of demersal fish. The results of the research on the diversity of demersal fish that have been found in the lower reaches of the Yeh Sungi River are quite diverse, based on the results of the study which captured 14 types of demersal fish in the lower reaches of the Yeh Sungi River. Feeding habits of 14 species found in demersal fish have nocturnal properties, by identifying the physical characteristics of demersal fish, especially in the form of mouths and fins, knowing some types of demersal fish that have adhesive fins prove that the fish look for food by attaching (passively) to the substrate of river rocks and tend to eat moss and detritus and are omnivorous. Demersal fish that do not have adhesive fins tend to be carnivorous and omnivorous, often looking for food by grabbing their prey, especially on the sand substrate on the riverbed. According to the results of analysis of abdominal surgery from 14 types of demersal fish found, 10 body cut objects from macrozoobenthos animals or food habits both intact and destroyed which were then matched with macrozoobenthos data which had previously been found on the bottom substrate downstream of the River. Yeh Sungi, the body pieces are white worms, red worms, silk worms / Tubifek sp, subsequent snails, small shrimp, short snails, dragonfly larvae, insects, detritus and moss.

Abstract

ABSTRACT Biodiversitas ikan-ikan air tawar lokal asli Indonesia sangat berlimpah namun belum banyak dimanfaatkan dalam budidaya. Pemanfaatan secara langsung masih dalam taraf penangkapan di alam yang dikhawatirkan dapat membahayakan populasinya di alam. Salah satu alternative untuk pencegahannya adalah dengan upaya meningkatkan budidaya dan mengurangi penangkapa The biodiversity of local freshwater fish native to Indonesia is very abundant but has not been widely used in aquaculture. Direct use is still within the level of capture in nature which is feared to endanger its population in nature. One alternative to prevention is to increase cultivation and reduce overfishing. Before carrying out fish farming first in domestication so that the fish are accustomed to living in a controlled environment. Feeding habits and growth Nyalian fish eat feed that floats or does not immediately sink to the bottom of the waters. It also corresponds to the position of his mouth looking up obliquely and his habits of life on the surface of the waters. The sampling method is Nyalian fish samples collected at two locations and data analysis on this research using SPSS. The growth of Rasbora lateristriata fish during domestication showed significant results, namely the absolute growth of the calculated t-test value of 16.948 with a significance level of 0.000. The growth of the total length with a calculated t-test value of 14.091 with a significance level of 0.000. Weight growth with a calculated t-test value of 9.045 with a significance level of 0.000. The relationship between length and weight shows significant results where the increase in standard length will be followed by weight growth. Water quality during the study, namely pH, DO and temperature is still following the life of Italian fish. The results of the study show that Nyalian fish can adapt to the artificial environment n yang berlebihan. Sebelum melakukan budidaya ikan terlebih dahulu di domestikasi agar ikan terbiasa hidup dilingkungan terkontrol. Kebiasaan makan dan pertumbuhan Ikan Nyalian memakan pakan yang terapung atau tidak langsung tenggelam ke dasar perairan. Hal itu juga sesuai dengan kedudukan mulutnya yang menengadah miring ke atas dan kebiasaan hidupnya di bagian permukaan perairan.

Abstract

Food waste in urban areas is an endless problem, considering that waste will continue to exist. The technique of managing waste to become an alternative feed for catfish is one of the steps to overcome the problem of waste and at the same time becomes an alternative fish feed solution for fish cultivators. The purpose of this research is to process food waste into fish feed. The method used in writing this article is literature review. Based on the results of the literature review and the author's analysis, it can be concluded that food ingredients that can be processed into catfish feed are food waste by utilizing fermentation or by mixing or formulated with other raw materials such as (fish meal, magot, tofu dregs, and fine bran). The fermentation process can use fishery products sold in the market, including (EM4, Boster, etc) which are mixed with molasses
