Abstract

In carp farming, it is not enough to rely solely on efforts to spur the growth of the fish, but it needs to be accompanied by efficient measures for the feed, this can be done by improving the quality of feed, especially the Feed energy. The source of fat that can be added to feed as an energy source is fish oil and lecithin. This research was aimed to findout the impact of the given various doses addition of the fish oil in the fish woof and to find out the best doses of the fish oil through the growth, the feed conversion ratio and the progression of carp fish life The study was conducted on December to January at Hatchery and Tecnology Aquaculture Laboratory, Faculty of Agriculture, University of Malikussaleh. The method used a nonfactorial completely randomized design with four treatments and three replications, namely A (fish oil 0,90 %), B (fish oil 1,2 %), C (fish oil 1,5 %) and D commercial feed (control). The result showed that fish oil with different doses had very significant different effect on growth, significantly different to feed conversion ratio and not significantly different to survival. the best treatment was found in treatment C by giving fish oil 1,5 %.Keywords: feed; fish oil; growth; carp

Abstract

Proses pengawetan ikan merupakan salah satu bagian penting dari mata rantai industri perikanan, dimana kesegaran ikan dipertahankan selama mungkin dengan cara menghambat penyebab kemunduran mutu. Penelitian ini bertujuan untuk memperoleh maserat kasar dari buah mangrove Avicennia marina yang berpotensi sebagai bahan pengawet alami ikan segar. Penelitian ini dibagi menjadi tiga tahap, yaitu tahap persiapan, maserasi dan aplikasi.  Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) Faktorial yang terdiri dari dua faktor. Faktor pertama adalah bentuk esktrak yang digunakan, yaitu maserat buah mangrove dan maserat serbuk buah mangrove. Faktor kedua adalah lama penyimpanan, yaitu 0, 4, 8, dan 12 hari. Masing-masing perlakuan diulang sebanyak dua kali. Data yang diperoleh berupa hasil uji fitokimia buah mangrove, kandungan protein ikan dan nilai organoleptik ikan nila selama penyimpanan. Data protein dan organoleptik dianalisis dengan ANOVA pada tingkat kepercayaan 95 %, apabila ada beda nyata maka dilanjutkan dengan uji lanjut Duncan. Hasil penelitian menunjukkan bahwa buah mangrove Avicennia marina mengandung senyawa fitokimia berupa alkaloid, flavonoid, terpenoid, saponin dan tanin. Berdasarkan analisis ragam interaksi antara bentuk maserat dan lama penyimpanan tidak memberikan pengaruh nyata terhadap kadar protein ikan nila. Secara keseluruhan, nilai organoleptik ikan nila dipengaruhi oleh interaksi antara bentuk maserat dan lama penyimpanan, dimana maserat serbuk memiliki nilai organoleptik lebih tinggi dibandingkan maserat utuh selama penyimpanan.The fish preservation process are an important partin the fishery industry, Fish freshness was maintained as long as possible by inhibiting the bacteria activity. The aim of this study was to utilized the maserate of fruit of Avicennia marina as a natural preservative agent. There are three parts in this research that are preparation, maceration and application. The factorial completely randomized design was used in this research, including two factors. First factor was the form of maserate (Powder and Dried mangrove fruit), and second factor was time storage (0, 4, 8, and 12 days), with every each treatment was repeated twice. Phytochemical of mangrove fruit, fish protein content and organoleptic value were test in this research. ANOVA (95%) was used to analyzed the organoleptic and protein data.  The results showed that mangrove fruit of Avicennia marina contains phytochemical compounds that are alakaloid, flavonoids, terpenoids, saponins and tannins. Based on analysis, interaction between maserate form and storage time were not have significant effect to protein content. Overall, the organoleptic value was influenced by the interaction between the maserate form and the time storage. The powder maserate has higher organoleptic value than the dried mangrove fruit during storage.

Abstract

A study on the cultivation of tilapia (Oreochromis niloticus) in brackish water using co-culture systems (polyculture, IMTA-non paddy, and IMTA-paddy) and monoculture systems was evaluated on a laboratory scale to determine its growth. Several species of aquatic animals and paddy (floating system) were combined with tilapia reared in plastic tanks for 28 days. Tilapia were fed four times a day at a feeding rate of 10% of biomass. The highest specific growth rate (SGR), IMTA-paddy system (4.24±0.08% day-1), polyculture (4.13±0.06% day-1), IMTA-non paddy (3.84±0.23% day-1), and monoculture (3.80±0.05% day-1). The same pattern was found in the addition of morphometric characteristics (AMC). Total length, standard length, body length, and height respectively from the highest IMTA-paddy system (2.49±0.12; 2.14±0.12; 1.81±0.14; 0.49±0.19 g), polyculture (2.32±0.16; 2.07±0.09; 1.72±0.11; 0.41±0.11 g), IMTA-non paddy (2.18±0.12; 1.78±0.15; 1.62±0.15; 0.33±0.14 g), and monoculture (2.02±0,09 1.67±0.08; 1.57±0.08; 0.30±0.10 g). Analysis of variance indicated that SGR and AMC of tilapia were significantly influenced by the culture system (P<0.05). The SGR and AMC in the IMTA-paddy system were significantly higher (P<0.05) than those in the monoculture and IMTA-non-paddy systems, but not significantly different (P>0.05) from those in the polyculture system. In general, tilapia growth was higher in co-culture systems than in monoculture systems in brackish water, which led to the diversification of aquaculture production.Keywords: Brackish water; Co-culture; Growth; Nile tilapia; Rice.
