Abstract

This study aimed to analyze the blood profile of tilapia (O. niloticus) on fortified feed with E. cottonii seaweed flour. This research was conducted for 60 days at the Laboratory of the Aquaculture Study Program, Faculty of Agriculture, University of Mataram. The method used was Completely Randomized Design (CRD) experiment with four treatments and three replications, namely P1 (without E. cottonii flour), P2 (E. cottonii flour 4%), P3 (E. cottonii flour 8%), P4 (E. cottonii flour 12%). The parameters measured were hematocrit, hemoglobin, erythrocytes, leukocytes, absolute weight, absolute length, SR and water quality including temperature, DO, and pH. Statistically analyzed at 5% significance level with 95% confidence level using ANOVA analysis and further test using Duncan's Multiple Range test. The results showed that the hematocrit value ranged from 10.67-13.67%, hemoglobin ranged from 5.1-9.1G%, erythrocytes ranged from 2.2x106-9.9 x106 cells/mm. leukocytes ranged from 11.4 x104-17.6 x104 cells/mm, absolute weight ranged from 16.26 -18.6 g, absolute length ranged from 5.08±0.50-5.91±0.27cm and survival (SR) ranged from 86.7±11.55-93.3±5.77%. Measurement of water quality, temperature 28-28.8, DO 6.8-7.5, and pH 7.43-7.99. The addition of different E. cottonii flour to tilapia feed affected hemoglobin, erythrocyte, leukocyte and growth levels, but did not affect hematocrit levels and survival rates. Supplementation of E. cottonii flour to a concentration of 12% in feed can increase hemoglobin, erythrocyte, and leukocyte levels so as to support better growth performance of tilapia

Abstract

Common carp (Cyprinus carpio) has become the option of aquaculture commodities which are generally found in farmers. This study aimed to evaluate the comparison of different breeding methods between natural, semi-artificial and artificial to the production of seed. The research methods included water and tank preparation, broodstock management, breeding activity, hatching eggs, rearing 7 days of larvae, nursery up to 30 days and harvesting. The results showed that there was a decrease in the weight of female fish after breeding with a percentage of 11,27% naturally, 6,11% semi artificially, and 5,7% artificially. The fecundity of the broodstock produced differed between treatments, namely by natural spawning 128,000 eggs, semi-artificial 68,034 eggs and artificially 24,537 eggs. Fertilization rate of fish obtained from natural breeding was 72%, semi-artificial 89% and artificial 81%. The hatching rate of fish obtained from natural breeding was 56%, semi-artificial was 79% and artificial was 63%. The survival rate of larvae was 90% from natural breeding broodstock, 75% from semi artificial breeding broodstock and 70% from artificial breeding broodstock. Seed survival rate was 15% from natural breeding broodstock, 12% from semi artificial breeding broodstock and 7% from artificial breeding broodstock. The weight absolute growth rate of seeds was 0.37 g with a length of 3.7 cm from natural breeding, 0.43 g with a length of 3.1 cm from a semi-artificial breeding and 0.25 g with a length of 2.5 cm from an artificial breeding. During the research, it was found that the water quality was still at optimal levels for common carp growth.

Abstract

Individu jantan Betta splendens memiliki warna dan bentuk yang digemari di pasar ikan hias dibandingkan betina. Karena itu budidaya cupang dapat dilakukan melalui produksi jantan menggunakan teknologi seks reversal dalam mengarahkan perkembangan kelamin ikan menjadi jantan (maskulinisasi). Bahan alami yang telah digunakan untuk maskulinisasi ikan adalah madu. Karena itu tujuan penelitian adalah mengkaji penggunaan madu melalui perendaman embrio untuk maskulinisasi ikan cupang. Keberhasilan maskulinisasi dianalisis melalui karakteristik madu, persentase ikan jantan, tingkat penetasan telur, mortalitas tiap 15 hari, dan sintasan pada akhir pemeliharaan. Embrio yang digunakan berumur 20 jam setelah pembuahan. Perlakuan penelitian adalah perendaman embrio cupang di dalam larutan madu (mL L-1) 5, 10, 15, 20, dan 25. Perendaman dilakukan selama 7 jam. Hasil penelitian menunjukkan bahwa madu yang digunakan memiliki kalium 0,31% dan pH 4. Pada penelitian ini pemberian madu tidak berpengaruh terhadap jumlah cupang jantan. Pemberian madu 25 mL L-1 air menghasilkan 56,98±4,58% jantan, tingkat penetasan telur 99,17±1,67%, dan sintasan umur 90 hari setelah menetas 79,89±4,50%. Mortalitas terjadi pada awal pemeliharaan larva. Setelah umur 60 hari setelah menetas tidak terjadi kematian pada cupang. Nilai tingkat penetasan telur dan sintasan yang tinggi menunjukkan bahwa madu adalah bahan alami yang aman digunakan untuk maskulinisasi ikan dalam budidaya monoseks.Individu jantan Betta splendens memiliki warna dan bentuk yang digemari di pasar ikan hias dibandingkan betina.
