Abstract

Freshwater crayfish (Cerax quadricarinatus) is a type of shrimp that is widely cultivated in Indonesia and other countries such as Australia, America and England. The high selling price of freshwater crayfish itself is still not comparable to the length of maintenance that takes 6-12 months for lobsters of 50-150 grams / head, and a high mortality rate of up to 30%. The aim of this research is to determine the survival and growth in freshwater crayfish through different shelter treatments. The method used in this study was the CRD method (completely randomized design) with 4 lecturers and 3 replications. In treatment 1 with Paralon pipe shelter, treatment 2 with coconut leaf shelter, treatment 3 with rooster rock shelter and treatment 4 with synthetic grass shelter. The results of the treatment had no significant effect on survival, moulting percentage, absolute weight growth and absolute length growth. There are 3 treatments with a percentage value of 100%, namely the S1, S2, S3 treatment and the lowest in the S4 treatment with a value of 95.83%, the highest moulting percentage is in the S1 treatment which is 0.38% and the lowest is in the S3 treatment which is 0.17 %. The highest absolute weight growth was found in S1 treatment, namely 3.11 gr and the lowest growth in S3 treatment, namely 1.19 gr. The absolute length growth shows the highest result is obtained at S1, namely 0.14 cm, while the lowest absolute length growth is found in S3, namely 0.06 cm.

Abstract

Koi fish (Cyprinus carpio) is a cultivated commodity that is in great demand by ornamental fish consumen. The research was conducted to determine the effect of different feeding options on the growth and survival of koi fish (Cyprinus carpio). The method used was a completely randomized design with 4 treatments and 3 replications. In P1 namely the use of pellet feed, P2 of artemia feed, P3 of Daphnia sp. feed, and P4 of silk worms. The parameters observed during the study were absolute length growth (PBM), absolute length growth (PPM) , survival rate (SR), and feed conversion ratio (FCR). The result of these observations had a very significant effect on the absolute length growth with the best treatment found at P4 of 2,34 cm, the growth in absolute weight had a very significant effect with the best treatment found at P4 of 3,41 g, and the feed convertion ratio has a very significant effect with the highest treatment found in P3 of 3,11. But it had no significant effect on the survival rate of koi fish (Cyprinus carpio).

Abstract

Tujuan dilakukannya penelitian ini adalah untuk mengetahui pengaruh penambahan pliek u pada pakan terhadap laju pertumbuhan dan kelangsungan hidup ikan lele Dumbo (Clarias Gariepenus).Metode yang digunakan pada penelitian ini adalah metode Rancangan Acak Lengkap dengan 4 perlakuan dan 4 ulangan. Pada perlakuan PO Tanpa pliek u, perlakuan P1 diberikan pliek u 10%, perlakuan P2 diberikan pliek u 15%, dan perlakuan P3 diberikan pliek u 20%. Hasil pengamatan diperoleh bahwa Perlakuan terbaik dari Survival Rate adalah pada P0 yaitu 72,50 %, pertumbuhan panjang terbaik adalah P3 10,17 , pertumbuhan berat terbaik adalah pada P0 4,9 dan perlakuan terbaik pada Fe Adalah 3,24 % Hasil analisis sidik ragam yang dilakukkan pertumbuhan panjang, pertumbuhan berat memiliki pengaruh yang sangat nyata sedangkan SR memiliki pengaruh yang nyata dan akan tetapi EP dan SGR memiliki pengaruh yang tidak nyata terhadap ikan lele dumbo (Clarias graipinus).

Abstract

: Depik fish (Rasbora tawarensis) is a type of freshwater fish that lives in Laut Tawar Lake, Central Aceh Regency. Depic fish is a pelagic endemic fish. This study aims to determine the best feed for (Daphnia sp.) on the growth and survival of depic fish (Rasbora tawarensis) seed. The method used was a completely randomized design (CRD) with 4 treatments and 3 replications, namely P1 (Daphnia sp. Given powder pellets). P2 (Daphnia sp. Given yeast feed). P3 (Daphnia sp. Given Spirulina) and P4 (Daphnia sp. Given Green water). Each treatment uses seeds measuring 2-3 cm. The parameters observed during the study were water quality, survival rate (SR), absolute weight growth (PBM), absolute length growth (PPM), and specific growth rate (SGR.The results of observations based on analysis of variance showed that Daphnia sp. Has significant effect (P <0.05) on absolute weight growth, absolute length growth but has no significant effect on specific growth rates and survival. The best treatment for different feeding in this study was P2 (yeast feeding) and P3 (spirulina feeding) treatment.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh media pemijahan yang berbeda terhadap kelangsungan hidup larva dan untuk mengetahui tingkat fekunditas ikan Mas koki Oranda (Carrasius auratus). Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 5 kali ulangan. Adapun perlakuannya meliputi penggunaan: A (Eceng gondok), B (Ijuk), C (Jaring kasa) dan D (Paranet). Dari hasil penelitian diperoleh data bahwa fekunditas tertinggi terdapat pada perlakuan A (Eceng gondok) dengan jumlah 677 butir telur, B (Ijuk) sebanyak 671 butir telur, D (Paranet) sebanyak 383 butir telur dan C (Jaring kasa) sebanyak 382 butir telur yang merupakan perlakuan terendah. Daya tetas tertinggi terdapat pada pada perlakuan A (Eceng gondok) yang mencapai 58 %, perlakuan B (Ijuk) mencapai 58 %, C (Jaring kasa) mencapai 75 %, lalu D (Paranet) mencapai 33 %. Dan tingkat kelangsungan hidup larva tertinggi terdapat pada perlakuan A (Eceng gondok) sebesar 60 %, perlakuan B (Ijuk) sebesar 60 %, lalu D (Paranet) sebesar 40 %, dan persentase kelangsungan hidup larva terendah terdapat pada perlakuan C (Jaring kasa) dengan nilai 30 %. Dari hasil analisis variansi menunjukkan bahwa ada pengaruh nyata (signifikan) pemberian media pemijahan yang berbeda terhadap kelangsungan hidup larva Ikan Maskoki Oranda (C. auratus) selama penelitian
