Abstract
Ikan wader cakul (Barbodes binotatus) merupakan perikanan air tawar yang memiliki nilai ekonomis yang tinggi. Permintaan pasar ikan wader cakul (B. binotatus) cukup banyak. Namun, kurangnya pemasokan yang cukup dan stabil untuk memeunih kebutuhan pasar sehingga dilakukan pemijahan ikan wader cakul. Pemijahan ikan merupakan suatu upaya untuk meningkatkan populasi ikan wader cakul. Pemberian substrat dalam pemijahan dapat membantu keberhasilan pemijahan ikan wader cakul. Substrat yang digunakan diantaranya tali rafia, batu dan eceng gondok (Eichhornia crassipes). Telur ikan wader akan menempel pada substrat. Tujuan dilakukannya penelitian ini adalah untuk mengetahui tingkat keberhasilan pemijahan ikan wader cakul (B. binotatus) dengan menggunakan substrat yang berbeda serta mengetahui fekunditas, hatching rate, dan survival rate larva ikan wader cakul (B. binotatus). Metode yang digunakan dalam penelitian ini adalah metode eksperimen. Perlakuan dalam penelitian ada 4 yang terdiri dari tali rafia, batu, eceng gondok (E. crassipes), dan kontrol. Parameter utama yang diamati dalam penelitian ini adalah fekunditas, daya tetas, dan survival rate larva ikan wader cakul (B. binotatus). Parameter penunjang yang diamati dalam penelitian ini adalah kualitas air pada media pemeliharaan ikan wader cakul (B. binotatus) yaitu suhu, pH, dan oksigen terlarut. Analisis data dilakukan dengan menggunakan analisis keragaman (ANOVA). Hasil penelitian ini menunjukkan bahwa perbedaan substrat memberikan pengaruh yang sangat nyata terhadap fekunditas. Fekunditas tertinggi terdapat pada perlakuan B (substrat batu) dengan jumlah rata-rata 2495 butir, sedangkan fekunditas terendah terdapat pada perlakuan A (substrat tali rafia) dengan jumlah rata-rata 1682 butir. Perbedaan substrat memberikan pengaruh yang sangat nyata terhadap daya tetas. Daya tetas tertinggi terdapat pada perlakuan B (substrat batu) dengan nilai rata-rata 81,98%, sedangkan daya tetas terendah terdapat pada perlakuan A (substrat tali rafia) dengan nilai rata-rata 58%. Perbedaan substrat memberikan pengaruh yang sangat nyata terhadap survival rate larva. Survival rate tertinggi terdapat pada perlakuan B (substrat batu) dengan nilai rata-rata 81,4%, sedangkan survival rate terendah terdapat pada perlakuan A (substrat tali rafia) dengan nilai rata-rata 44,4%. Kualitas air selama penelitian termasuk optimal untuk pemijahan ikan wader cakul (B. binotatus) Penggunaan substrat yang berbeda memberikan pengaruh terhadap fekunditas, daya tetas, dan survival rate larva ikan wader cakul (B. binotatus). Hasil terbaik diperoleh dari perlakuan B dibandingkan dengan perlakuan A, C dan kontrol.
English Abstract
Spotted barb fish (Barbodes binotatus) is a freshwater fishery that has high economic value. The market demand for spotted barb fish (B. binotatus) is quite a lot. However, there is a lack of sufficient and stable supply to meet market demand, so the spawning of spotted barb fish is carried out. Spawning fish is an effort to increase the population of spotted barb fish. Provision of the substrate in spawning can help the success of spawning wader hoe fish. The substrates used include raffia rope, stone, and water hyacinth (Eichhornia crassipes). Spotted barb fish eggs will stick to the substrate. The purpose of this study was to determine the spawning success rate of the spotted barb (B. binotatus) using different substrates and to determine the fecundity, hatching rate, and survival rate of the spotted barb (B. binotatus) larvae. The method used in this research is the experimental method. There were 4 treatments in the study consisting of raffia rope, rock, water hyacinth (Eichhornia crassipes), and control. The main parameters observed in this study were fecundity, hatching rate, and survival rate of spotted barb fish (B. binotatus) larvae. Supporting parameters observed in this study were water quality in the spotted barb (B. binotatus) rearing medium, namely temperature, pH, and dissolved oxygen. Data analysis was performed using analysis of variance (ANOVA). The results of this study indicate that differences in substrate have a very significant effect on fecundity. The highest fecundity was in treatment B (stone substrate) with an average number of 2495 grains, while the lowest fecundity was in treatment A (raffia rope substrate) with an average number of 1682 grains. Substrate differences have a very significant effect on hatchability. The highest hatching rate was in treatment B (rock substrate) with an average value of 81.98%, while the lowest hatchability was in treatment A (raffia rope substrate) with an average value of 58%. The difference in the substrate has a very significant effect on the survival rate of the larvae. The highest survival rate was in treatment B (stone substrate) with an average value of 81.4%, while the lowest survival rate was in treatment A (raffia rope substrate) with an average value of 44.4%. The quality of the water during the study was considered optimal for the spawning of the spotted barb (B. binotatus). The use of different substrates affects the fecundity, hatchability, and survival rate of the spotted barb (B. binotatus) larvae. The best results were obtained from treatment B compared to treatments A, C, and control.
