Abstract

Tujuan dari penelitian ini adalah untuk menganalisis perubahan dalam perkembangan gonad kerang Anadara granosa di Lhokseumawe, bagian utara Selat Malaka dalam hubungannya dengan fluktuasi kualitas air harian. Untuk menentukan periode pemijahan populasi kerang, dilakukan analisis indeks kondisi (condition index/CI). Sampel kerang dikumpulkan dari Juli 2009 sampai Mei 2010 dan parameter kualitas air turut diukur secara berkala. Indeks kondisi tertinggi dari populasi kerang diamati pada Oktober 2009 (13.97±3.49), sedangkan indek kondisi terendah ditemukan pada Januari 2010 (6.76±1.13). Periode pemijahan untuk A. granosa diketahui terjadi terus-menerus sepanjang tahun, dengan puncak pemijahan terjadi pada bulan Oktober 2009 sehingga Januari 2010. Suhu air dan salinitas harian di lokasi penelitian berkisar antara 24-34 oC dan 27-33 ppt. Periode pemijahan populasi A. granosa diketahui bertepatan dengan terjadinya fluktuasi secara drastis pada suhu air dan salinitas harian. Analisis kualitatif menunjukkan bahwa suhu dan salinitas adalah modulator utama peristiwa reproduksi. Ketika suhu dan salinitas berfluktuasi, aktifitas pemijahan secara sporadis terdeteksi pada spesies ini. Penelitian ini juga menunjukkan bahwa periode pemijahan yang diikuti oleh proses rekrutmen dalam populasi kerang A. granosa Lhokseumawe sangat tergantung pada kondisi lingkungan kawasan tersebut..

Abstract

Introduction fish in Indonesia has been negatively impact to the water ecology, such as declining in the number of native fish species. Handling the negative impacts of introduced fish can be minimized by reducing fertility rates through the use of plant compound extracts. This study was conducted in May - June 2016 which aimed to assess the effectiveness of the papaya seed flour (Carica papaya L) for the reproductive function of introduction fish Oreochromis niloticus. The research design used in this study was completely randomized design, non-factorial with five treatments and three replications, namely A: control (without giving the flour), B: 40 mg, C: 50 mg, D: 60 mg, E: 70 mg of papaya seeds flour mixing in 100 grams of artificial feed. The fish sample used were 45 mature tilapia fish, 4-5 months old with 200 g in weight for female and 250 gram in weight for male. Parameters measured in this research were feed consumption level, fecundity, fertilization rate, hatching rate and sperm morphological structures. The results of this study indicated that the papaya seed flour gave the multiple effect on the sperm abnormality and decreased the motility level of sperm. Statistical analysis showed that the application of papaya seed flour gave significantly different effect (P <0.05) between treatments on percentage of fertilization level and hatching rate parameters, but showed not significantly different on survival rate parameter where P> 0.05. The lowest sperm motility rate was found in treatment E, which was 00.45 ".032 /second. The average eggs number in this study ranged from 994,33 to 1.416 grains, whereas the lowest fertilization level and the lowest hatching rate was in treatment E with the percentage 58.58% and 99.24%.
