Abstract

The potensi of sea weeds farming development in Indonesia is very big, because of large suitable locations, high sea weeds variety, simple technology and small capital relatively. But now this effort facing serious problem that caused by ice-ice disease. That disease usually happen when rainy (October-April) and catching becaused bacterium and the effect of more old the sea weeds and less nutrition. Ice-ice was signed by red pocks then yellow, white and then moults. The change environment suddenly such us salinity, temperature and light intensity were main factor that triggers ice-ice. Pseudoalteromonas gracillis, Pseudomonas spp. and Vibrio spp can isolated from sea weeds that attackted. Remember that disease is so harm, so need to do efforts to solve that problem. One of sollution is do the right and consistent of standard operating procedure (SOP) in sea weeds farming. This SOP consist of three stages, choose suitable locations, qualified sea weed seeds and use sitable technology. Wish the lost of economic will be minimal with applying this SOP.

Abstract

Knife fish (Chitala lopis) is one kind of freshwater fish of high economic value.Therefore the arrest activity continued and resulted in knife fish increasinglyscarce fish. The purpose of this study to determine the reproductive potential ofknife fish. Research carried out for four months in Tulang Bawang river,Lampung. Fish samples collected from the fisherman and gatherers along therivers. Observations were made include: morphology, length and weight, sexratio, gonado maturity level (GML), gonado somatic index (GSI) and fecundity.Total length of knife fish average 50,9 cm, 15,6 cm in height and weighing 883,90grams. Length and weight relationship is expressed by the equationW=0,0459L2,5005 which means that the type of fish growth is negative allometric.The number of knife fish more female than male, which sex ratio between malesand females 1 : 2,3. Most of the knife fish is immature gonads (GML I and II)with 0,35 gonado somatic index. Many knife fish immature gonads because thefish was not spawning season. Fecundity ranged of knife fish is 207-412 eggs oraverage of 290 eggs per fish.

Abstract

Catfish (Pangasius hyphothalmus) is one type of freshwater economicalfish that begins developed by fish farmers to cultivation. Catfish are easy to breed,easy maintenance and fast growth. The problem that often be faced in catfishcultivation is the high price of fish diets. One source ingredient used in theformulation of the diet is soybean meal, but the price is relatively expensivebecause of the imported commodity. To reduce dependence on soybean meal, it isnecessary to find an alternative source of local commodity are easily obtained,continuous availability, and have high nutritional value, namely the use velvetbean meal (Mucuna pruriens). The research was aimed to study the utilization ofvelvet bean meal as substitution of soybean meal on diets to the growth of catfishfingerlings. A completely randomized design was five treatments and threereplications. The treatments used applied 0%, 25%, 50%, 75%, 100% velvet beanmeal percentation. Data were analyzed by using ANOVA. The result showeds thattreatment of diet did not give significant influence to the growth of catfishfingerlings. It can be concluded that the velvet bean meal can be used to substitutesoybean meal on diets to the growth of catfish fingerlings from substitution rate of25% to 100%. The best percentage is level substitution 75 % velvet bean meal +25% soybean meal.

Abstract

Tambaqui fish much culture in Indonesia because have a fast growth andresistant to diseases. The latest aquaculturist problem is the high price of fishfeed. One of materials used in fish feed formulation is soybean meal which is veryexpensive, because it is an import basic commodity. One of alternative toovercome these problems is to replace with local raw materials such as rubberseed meal with a potentially lower the cost of feed production. The research tostudy the effect of rubber seed meal as a substitution of soy bean meal. Theresearch was conducted by using completed random design with six treatment andthree replications that which had different level comparation of soy bean meal andrubber seed meal, as follows A (45% : 0%); B (40% : 5%); C (30% : 15%); D(20% : 25%); E (10% : 35%) and F (0% : 45%). The data was analysed by Anovaand continued with least significantly different test (P>0,05). The rubber seedmeal as a substitution of soy bean meal were not significantly different on thegrowth rate. The rubber seed meal 5% it can be concluded, substitution of soybean meal 40% with 5% rubber as a substitute for soybean meal in feed to a hadthe growth (9,9 g) were not significantly different (P>0,05) with the used of feedis no substitution of rubber seed meal (10,2 g) of tambaqui fish. substitution ofsoy bean meal with rubber seed meal at level 5% can be used as feed formulationof tambaqui fish.

Abstract

Biofloc system is a technology in aquaculture which utilized waste mainly in form of anorganic nitrogen. The anorganic nitrogen will be converted into protein in the form of bacterial biomass by heterotrophic bacteria. The growth of heterotrophic bacteria is stimulated by the addition of a carbon source. This research aimed were to study the absolute growth, daily growth rate, specific growth rate and survival rate of tilapia and sangkuriang catfish which fed on biofloc. The research used Completely Randomized Design (CRD) which consisted of two treatments and four replication. The study lasted for 40 days, with the frequency of feeding biofloc was three times a day ie morning, afternoon and evening. Growth sampling was done every 10 days, observation of water quality every 8 days, and ammonia test was done at the beginning, middle and end of research. The results showed that tilapia which fed on biofloc have absolute growth, daily growth rate, specific growth rate, and survival rate better than those of sangkuriang catfish.

Abstract

Salah satu faktor penting dalam budidaya ikan nila adalah ketersediaan pakan yang memadai. Ikan nila (Oreochromis sp.) merupakan ikan air tawar yang memiliki nilai ekonomis tinggi dan banyak dibudidayakan, namun pembudidaya sering mengalami kendala karena harga pakan yang tinggi. Hal ini terjadi karena bahan baku pakan seperti tepung ikan masih diimpor. Untuk mengatasinya perlu alternatif sumber bahan baku salah satunya adalah memanfaatkan limbah kepala ikan teri. Penelitian ini bertujuan untuk memperoleh formulasi pakan yang terbaik untuk pertumbuhan ikan nila, menggunakan Rancangan Acak Lengkap dengan 5 perlakuan dan 3 kali ulangan A (tepung ikan 100%), B (tepung kepala ikan teri 25% dan tepung ikan 75%), C (tepung kepala ikan teri 50% dan tepung ikan 50%), D (tepung kepala ikan teri 75% dan tepung ikan 25%), E (tepung kepala ikan teri 100%). Data yang diperoleh dianalisis ragam dan dilanjutkan dengan uji BNT. Parameter yang diamati berupa: pertumbuhan, retensi protein, feed convertion ratio (FCR), dan survival rate (SR). hasil pengamatan menunjukkan bahwa penggunaan tepung kepala ikan teri dalam pakan buatan pada perlakuan E memberikan pengaruh nyata dibandingkan perlakuan A, B, C, dan D yakni didapat pertumbuhan, dan retensi protein tinggi, sedangkan nilai FCR rendah. Hal tersebut menyatakan bahwa tepung kepala ikan teri mampu menggantikan tepung ikan.KATA KUNCI: Ikan nila, limbah ikan teri, pakan.
