Abstract

The main problems faced by fish farmers are waste, uneaten feed and feces.  Which can reduce water quality and have a significant impact on fish growth and survival. This study aims to determine the effect of giving various types of probiotics on the growth rate and viability of Mutiara catfish raised using the biofloc system. We used Lactobacillus sp., Bacillus subtilis, and Nitrobacter as probiotic bacteria. This study used a completely randomized design experimental method with 4 treatments and 3 replications, namely K = probiotic less/control, P1= Lactobacillus probiotic, P2= Bacillus subtilis probiotic, P3= Nitrobacter probiotic. Catfish are reared for 30 days, feeding 3 times a day with FR 5% of body biomass. The parameters observed were absolute length growth, survival, Feed Conversion Ratio (FCR) and Specific Growth Rate (SGR) which were analyzed using ANOVA (P <0.05) and Duncan's test to see the differences between treatments. The results showed that the bacteria probiotic treatment had no significant effect on FCR and fish survival, but had a Lactobacillus sp significant effect on growth in absolute length (3.96 ± 0.06 cm) and the growth rate of daily specific weight (5,45±0,18 %/day).  To increase the length and weight growth of catfish fry, probiotic bacteria of the type Lactobacillus sp. on cultivation media.Key words :biofloc, growth rate, lactobacillus, mutiara catfish, probiotics

Abstract

Dry land-based catfish fishery is one of the promising rural aquabusiness in Gunungkidul, Yogyakarta. There are several problems in this business, for example, supply-demand balancing, calculation accuracy of production capacity, and equitable profit distribution to each stakeholder. This research aimed to design a closed-loop supply chain of dry-land catfish industrial-fishery model by employing the system dynamics approach. Powesim Studio 7 coupled MINITAB 14 was applied to measure the robustness of the supply chain management system, to predict optimum production capacity, and to balance profit distribution. A financial analysis was also performed to determine business feasibility. Three scenarios of price were created by considering the predicted trend of catfish consumption and formulated three alternative prices by appraising the juvenile fish production, aquaculture practices, local feedstock manufactured by farmers, and fish-by products distributed by small-enterprises. Those consideration units were constructed of four observed models. The highest profit to stakeholder was obtained by scenario III that was directed to increase the juvenile fish price to Rp 240/fish, consumption-sized fish at the price of Rp 18,000/kg, fish-by product at the price of Rp 150,000/kg, and local feed at the price of Rp 9,000/kg. According to financial analysis, the four subsystems in dry land-based catfish aquabusiness were all feasible by BCR>1; PP was 5-9 years, NPV>0, PI>1, and IRR>15%/year. The implementation of the system required synergetic action among policymakers, farmer cooperative, and local innovation centers.

Abstract

Intensive aquaculture system decreases water quality through the increment of metabolic waste products such as organic nitrogen. The biofloc technology is an alternative solution to avoid the impact of high nutrients disposal in aquaculture production system. This study aimed to evaluate the impacts of biofloc technology using different carbon sources on the production performance of juvenile striped catfish, Pangasianodon hypophthalmus. Completely randomized design with 4 treatments (3 replications) was used in this research i.e.: (A) molasses carbon source, (B) tapioca carbon source, (C) wheat carbon source, and (D) without additional carbon. The juveniles length 2.26±0.12 cm, initial average body weight 0.17±0.05 g were reared for 30 days. Twelve glass tanks (60 cm x 30 cm x 40 cm) filled with 36 L freshwater were used as the experimental culture units. The fish were fed three times daily with a commercial feed containing 27% of crude protein. External organic carbon was added daily two hours after feeding at C/N 15 estimated ratio. The observed parameters i.e.: floc profile, the nutritional content of biofloc, water quality, survival rate, final body length, daily growth rate, feed conversion ratio, protein retention, and lipid retention. The best results showed by molasses treatment, the highest fish survival rate (97.41±0.16 %), longest standard length (2.84±0.1 cm) and decreased feed conversion ratio (0.36±0.04). Abstrak Sistem budi daya intensif menurunkan kualitas air melalui peningkatan produk sisa metabolisme seperti nitrogen or-ganik. Penerapan teknologi bioflok adalah solusi alternatif untuk menghindari dampak buruk pembuangan nutrisi tinggi dalam sistem produksi akuakultur. Penelitian ini bertujuan untuk mengevaluasi pengaruh teknologi bioflok yang menggunakan sumber karbon berbeda pada kinerja produksi yuwana ikan patin (Pangasianodon hypophthal-mus). Rancangan penelitian yang digunakan adalah rancangan acak lengkap dengan empat perlakuan (tiga kali ulang-an) yaitu: (A) sumber karbon molase, (B) sumber karbon terigu, (C) sumber karbon tapioka, dan (D) tanpa penam-bahan karbon. Yuwana ikan patin berukuran panjang awal 2,26±0,12 cm ekor-1 dan bobot rata-rata awal 0,17±0,05 g ekor-1 dipelihara selama 30 hari. Dua belas akuarium (60 cm x 30 cm x 40 cm) diisi dengan air 36 L digunakan seba-gai unit percobaan budi daya. Ikan diberi makan tiga kali sehari dengan pakan komersial mengandung protein 27%. Penambahan karbon dilakukan setiap hari 2 jam setelah makan dengan estimasi rasio C/N 15. Parameter pengamatan meliputi: profil flok, kandungan nutrisi tepung flok, kualitas air, kelangsungan hidup, pertumbuhan panjang baku, la-ju pertumbuhan harian, rasio konversi pakan, retensi protein, dan retensi lemak. Perlakuan dengan penambahan sumber karbon molase menunjukkan kelangsungan hidup tertinggi (97,41±0,16 %), pertumbuhan panjang baku (2,84±0,1 cm), dan menurunkan rasio konversi pakan (0,36±0,04).
