Pengaruh Pemberian Probiotik Pada Media Pemeliharaan Terhadap Kualitas Air Dan Pertumbuhan Benih Ikan Baung (Mystus Nemurus)

Variasi genetik dan morfometrik beberapa ras ikan baung yang dikoleksi dari Jambi, Wonogiri, dan Jatiluhur telah diteliti dengan menggunakan polimorfisme mitokondria DNA D-loop dan metode truss morphometric. Berdasarkan kedua metode tersebut terdapat perbedaan yang nyata antara ras ikan baung dari Jambi dengan Wonogiri dan Jatiluhur, dan tidak berbeda nyata antara ras Jatiluhur dengan Wonogiri.

Mystus Nemurus

Danau Bakuok yang terletak di Kabupaten Kampar merupakan salah satu contoh suaka perikanan di Propinsi Riau yang penetapan dan pengelolaannya berdasarkan hukum adat. Berbagai jenis ikan yang memiliki nilai ekonomis penting terdapat di danau ini antara lain ikan patin (Pangasius sp.), ikanlais (Kryptopterus spp.), dan baung (Hemibagrus nemurus sinonim Mystus nemurus), serta ikan motan (Thynnichthys thynnoides) yang merupakan jenis ikan khas Danau Bakuok. Kegiatan penangkapan ikan hanya boleh dilakukan 1 kali dalam 1 tahun yang dinamakan sebagai acara ma’awuo dan dilaksanakan menjelang bulan Ramadhan. Hasil tangkapan ikan setiap tahun cenderung menurun dan diduga telah terjadi penurunan stok sumber daya ikan. Untuk memperbaiki kondisi ini, pada tahun 2004 pemerintah Propinsi Riau melakukan upaya pengkayaan stok (restocking) berupa penebaran benih ikan baung.

Tujuan penelitian ini adalah untuk mengetahui komposisi dan fluktuasi hasil tangkapan tuguk pada periode berbeda yang dioperasikan di Sungai Lempuing, Sumatera Selatan. Kegiatan penelitian dilaksanakan dengan metode survei pada periode musim peralihan penghujan sampai dengan kemarau (bulan April), musim kemarau (bulan Juni) dan musim penghujan (bulan Desember) tahun 2007. Komposisi jenis ikan dan hasil tangkapan diperoleh berdasarkan pada data pengambilan contoh pada saat ke lapangan dan data harian hasil tangkapan tuguk yang dicatat oleh 3 orang enumerator. Data dianalisis secara deskriptif. Hasil penelitian menunjukkan bahwa hasil tangkapan tuguk berbeda menurut periode waktu. Hasil tangkapan terdiri atas 11 jenis ikan untuk musim peralihan dan kemarau masing-masing berkisar 400-450 kg per unit per hari (rata-rata 411,2+14,1 kg per unit per hari) dan 250-300 kg per unit per hari (rata-rata 263,3+13,4 kg per unit per hari) dan 13 jenis ikan pada musim penghujan (bulan Desember) berkisar 700-750 kg per unit per hari (rata-rata 724,8+17,7 kg per unit per hari). Hasil tangkapan didominansi oleh jenis ikan lele (Clarias melanoderma) dan baung (Mystus nemurus). Selama penelitian, kandungan oksigen terlarut di perairan relatif rendah, berkisar 2-4 mg per l, namun dapat ditolelir oleh kelompok jenis ikan rawa (black fish). This research proposed to observed a catch composition and fluctuation of filtering device in different periods operated in the Lempuing River, South Sumatera. The research was conducted using survey method at a respective month of April (transition season), June (dry season) and December 07 (wet season). Fish composition and catch of tuguk were noted during survey and based on recording 3 enumerators. Descriptive analysis was used in this study. The results show that the catch of filtering device differed on diferent season periodes. A number of 11 fish species was caught at a respective season of transition season (April) of 400-450 kg per unit per day (average=411.2+14,1 kg per unit per day), dry season (June) of 250 300 kg per unit per day (average = 263,3+13,4 kg per unit per day), whilst at rainy season (December), fish catch composed of 13 fish species, ranging 700-750 kg per unit per day or (average = 724.8+17.7 kg per unit per day). Clarias melanoderma and Mystus nemurus were dominantly caught in the Lempuing River waters. During observation, dissolved oxygen content was relatively low (2-4 mg per l), that but could be tolerated by black fish.

This research was conducted to evaluate the fish distribution and biodiversity within three types of swamp ecosystem with different water sources in Pampangan Sub-district during July to December 2011. The field observation were conducted in three different types of swamp. Ecological data and samples were collected from three sampling points in each swamp type. Parameters including local distribution, diversity index, similarity index, evenness and species richness, were analyzed. The results show a number of 9,723 fishes corresponding to 46 species were collected, the fish categorized into 16 families belonging to five orders. Eight species were found in all type of swamps i.e. Mystus nemurus, Channa striata, Cyclocheilchthys apogon, Cyclocheilichthys armatus, Pristolepis fasciata, Puntius lineatus, Osteochillus hasselti, and Trichogaster pectoralis. A diversity index of fishes in Pampangan Swamp ranged from 2.31 to 2.85, indicating moderate values. The evenness index was high more than 50%. The highest similarity was found between type 1 and type 3 of (0.43). The highest diversity index (2.85) found in type 2 of swamp indicates the swamp in more stable condition.

Mystus Nemurus

This study integrates mathematical model in the plan of producing a fish feed formulation by reducing the total cost without neglecting the nutrient requirements. This study focuses on producing the perfect combination of fish feed for Mystus nemurus sp. catfish in different stages of life. The mathematical model developed will consider their required nutrients in each stage, the cost of each ingredient and the amount of nutrients to be consumed (nutrient composition of fish feed ingredients). This research employs AIMMS mathematical software to assist with the computation. The results from this study obtain a much better combination of different ingredients compared to available commercial pellets in terms of nutrient composition and production cost. The combinations yield much cheaper costs yet boosts up the nutrient consumptions, which is an eye-opener for independent local fish farmers. Thorough discussion on utilizing the results with future research directions will also be included.
