Abstract
Budidaya udang intensif merupakan kegiatan yang dikembangkan di Kawasan Pesisir Indonesia. Salah satu aspek penting dalam akuakultur adalah keberadaan mikroorganisme yang berperan sebagai bioindikator pakan alami dan kualitas air. Kehadiran pakan alami dapat meningkatkan efisiensi pakan buatan dan mengoptimalkan pertumbuhan udang. Kendala bagi pembudidaya yang menggunakan tambak intensif adalah meningkatnya nutrien dari feses, sisa pakan dan sisa udang mati yang memicu eutrofikasi dan berpotensi HABs untuk blooming. Solusi yang diberikan yaitu dinamika kualitas air dan fitoplankton bagi pertumbuhan udang untuk mendukung stabilitas ekosistem akuakultur. Tujuan penelitian ini yaitu menganalisis dinamika fitoplankton dari perbedaan tipe kolam budidaya dan padat tebar terhadap pertumbuhan udang vaname di Desa Bayeman Kecamatan Tongas, Kabupaten Probolinggo dan Menganalisis dinamika kualitas air terhadap perbedaan tipe tambak budidaya dan padat tebar terhadap pertumbuhan udang vaname di Desa Bayeman, Kecamatan Tongas, Kabupaten Probolinggo. Teknik pengumpulan data menggunakan purposive sampling. Hasil temuan penelitian ditemukan 4 Divisi dengan 41 Genera yang didapatkan pada tambak udang sedangkan pada variasi isi lambung udang ditemukan 4 Divisi dengan 12 Genera. Nilai kelimpahan fitoplankton pada perbedaan kedalaman memiliki range berkisar 45-592 sell/ml, sedangkan kelimpahan fitoplankton di variasi isi lambung udang vaname memiliki range 3-64 cell/ml. Keanekaragaman fitoplankton di tambak memiliki indeks sedang hingga tinggi, sedangkan pada variasi isi lambung udang memiliki indeks rendah hingga sedang. Keseragaman fitoplankton di tambak dan isi variasi Lambung udang vaname memiliki indeks keseragaman jenis yang tinggi. Indeks dominansi fitoplankton di tambak dan variasi isi lambung udang bahwa tidak ada genus yang mendominasi hingga terdapat genus yang mendominasi. Dominansi terjadi pada sampling sore DOC ke-63 di tipe tambak Intensif dikarenakan terindikasi infeksi WSSV sehingga dilakukan pemanenan dini. Laju pertumbuhan Relatif udang vaname ditemukan berkisar 0,23 -0,27 gr, Pertumbuhan mutlak berkisar 1,61 – 1,91 dan Tingkat kelulusan hidup udang vaname selama satu siklus budidaya sebesar 64,4 – 81.6%. Hasil analisis statistika menggunakan analisis korelasi pearson menunjukkan bahwa pengaruh terbesar pada kelimpahan fitoplankton adalah ortofosfat di dalam air tambak dengan hasil korelasi positif tinggi sebesar 0,958 (P Value < α 0,05). Hasil analisis statistika CCA menunjukkan bahwa ortofosfat mempengaruhi pertumbuhan genera Tribonema, Stephanodiscus dan Aphanocapsa
English Abstract
Intensive shrimp farming is an activity developed in the Indonesian Coastal Zone. One important aspect of aquaculture is the presence of microorganisms which act as bio-indicators of natural feed and air quality. The presence of natural feed can increase the efficiency of artificial feed and optimize shrimp growth. The obstacle for farmers who use intensive ponds is the increase in nutrients from feces, leftover feed and dead shrimp residue which triggers eutrophication and has the potential for HABs to flower. The solution provided is the dynamics of water quality and phytoplankton for shrimp growth to support the stability of the aquaculture ecosystem. The purpose of this study was to analyze the dynamics of phytoplankton from differences in the types of aquaculture ponds and stocking density on the growth of vannamei shrimp in Bayeman Village, Tongas District, Probolinggo Regency and to analyze the dynamics of air quality for differences in the types of aquaculture ponds and stocking density on the growth of vannamei shrimp in Bayeman Village, Tongas District, Probolinggo Regency. Data collection technique using purposive sampling. The research findings found 4 divisions with 41 genera which were found in shrimp ponds, while in variations of shrimp stomach contents, 4 divisions with 12 genera were found. The reading value of phytoplankton at different depths has a range of 45-592 cells/ml, while the phytoplankton tick in the Vaname Shrimp hull content variation has a range of 3-64 cells/ml. The diversity of phytoplankton in the ponds has a moderate to high index, while variations in shrimp stomach contents have a low to moderate index. Phytoplankton uniformity in ponds and content variation Vannamei shrimp hulls have a high species uniformity index. The index of the dominance of phytoplankton in ponds and variations in the contents of the stomach of shrimp that there is no dominating genus until there is a dominating genus. Dominance occurred in the afternoon sampling of the 63rd DOC in the Intensive pond type due to indications of WSSV infection, so early harvesting was carried out. The relative growth rate of vannamei shrimp was found to be around 0.23 -0.27 gr, the absolute growth ranged from 1.61 - 1.91 and the acceptance rate of live vannamei shrimp during one cultivation cycle was 64.4 - 81.6%. The results of statistical analysis using Pearson correlation analysis showed that the biggest effect on phytoplankton traps was orthophosphate in pond water with a high positive correlation of 0.958 (P Value < α 0.05). The results of the CCA statistical analysis showed that orthophosphate affected the growth of the Tribonema, Stephanodiscus and Aphanocapsa genera.
