BUDIDAYA MUJAIR PDF

Budidaya perikanan air tawar memiliki beberapa alternatif ikan yang memiliki nilai ekonomis tinggi yaitu ikan Mas, ikan Mujair, ikan Nila, ikan Gurame, ikan Lele dan ikan Patin. Alternatif ikan ini memiliki karakteristik yang berbeda untuk masing-masing jenis pembudidayaannya. Parameter-parameter yang mempengaruhi proses budidaya ikan air tawar tersebut diantaranya: f aktor kesesuaian air meliputi: s uhu, k ecerahan, DO derivater oksigen , k easaman pH. Sedangkan metode yang dipergunakan untuk pengambilan keputusan yaitu Technique for Order Preference by Similarity to Ideal Solution TOPSIS sebagai salah satu model decision dapat digunakan untuk memberikan preferensi kepada para petani budidaya ikan, karena alternatif yang terpilih tidak hanya memiliki jarak terpendek dari solusi ideal positif tetapi juga jarak terpanjang dari solusi ideal negatif. Hasil dari penelitian ini menunjukkan bahwa sistem penunjang keputusan yang mempertimbangkan parameter kondisi lingkungan air dan faktor finansial dapat membantu petani budidaya ikan untuk menentukan jenis budidaya ikan air tawar yang akan dijalankan.

Abstrak Ikan Mujair Oreochromis mossambicus merupakan organisme perairan tawar dan merupakan ikan yang telah beradaptasi luas di Indonesia karena kemampuan berkembangbiaknya yang cepat. Salah satu kendala dalam budidaya perikanan yakni Salah satu kendala dalam budidaya perikanan yakni permasalahan yang timbul dalam meningkatkan ketahanan pangan dalam produk hewani diantaranya penyediaan pakan budidaya ikan yang mahal, sulit untuk didapat, dan kurang berkualitas, oleh sebab itu diperlukan bahan alternatif sebagai tambahan pakan untuk menjamin kegiatan budidaya.

Salah satu bahan tambahan pada pakan yang dapat mendukung tingkat kelangsungan hidup dan laju pertumbuhan ikan mujair yakni jintan hitam Nigella sativa yang berperan sebagai antioksidan karena mengandung beberapa bahan aktif diantaranya, Thymoquinone, Dithymoquinone, Thymohidriquinone, dan Thymol Endarti, Tujuan dari penelitian ini adalah untuk mengetahui pengaruh dari penambahan tepung jintan hitam pada pakan komersial terhadap tingkat kelangsungan hidup dan laju pertumbuhan spesifik ikan mujair Oreochromis mossambicus.

Metode yang digunakan dalam penelitian ini adalah metode eksperimental dengan menggunakan Rancangan Acak Lengkap RAL dengan empat perlakuan dan lima ulangan. Hasil dari penenlitian ini menunjukkan bahwa penambahan tepung jintan hitam pada pakan komersial ikan mujair selama 28 hari dapat meningkatkan kelangsungan hidup pada beberapa dosis tertentu serta laju pertumbuhan spesifik dianggap sama antar perlakuan. The present investigation envisage a study of the effects of pesticides on four fin fishes Oreochromis mossambicus from mahua oil cake, a derived from the plant Madhuca longi folia seed.

Although some reports on the effects of mahua oil Although some reports on the effects of mahua oil cake on fin fishes and Madhuca seed on fresh water pond culture systems are available, information on their effect on brackish water culture systems are rather scanty. Fishes along with the shrimps were taken at 10, 20, 30 ppt salinity and mahua oil cake MOC was applied at 10, 15, 20 ppm concentrations to see the mortality timings of the fishes.

Phyisco-chemical parameters and LC50 concentration were recorded in the study. Lethal concentration LC50 was recorded for the species Elops machnata the concentration was found to be 5ppm.

Vinothkumar Rupam Dey Dr. The developing central neural circuits in teleosts are genetically controlled and temperature-initiated. We compiled a list of transcripts expressed in the developing tilapia Oreochromis mossambicus brain using expressed sequence tags We compiled a list of transcripts expressed in the developing tilapia Oreochromis mossambicus brain using expressed sequence tags derived from the developing brain, and investigated genes with thermosensitive ontogenetic expression. Of clones, were unique genes, of which were known.

Fourteen of the latter were neural development-related, and the ontogenetic expression of nine was temperature-influenced. Discs large homolog 5, myelin expression factor 2, plasticity-related protein-2, tsc2 gene product-related genes, and an inhibitor of differentiation protein 2 Id2 were differentially temperature-influenced according to their developmental stages.

Endothelial differentiation-related factor 1, midkine-related growth factor b, and mitogen-activated protein kinase 14b were specifically influenced by elevated temperature, and beta-catenin-like isoform 1 by lower temperature. Neural development-related genes, particularly those with thermosensitive ontogenetic expression, might be important for developing central neural circuits in teleosts.

Prolonged apoptosis in mitochondria-rich cells of tilapia Oreochromis mossambicus exposed to elevated salinity.

The rapid growth of offshore oil and gas exploration on the Western Indian Continental shelf has generated the need for both general and region-specific scientific information on the environmental consequences of drilling activities.

Much of the toxicity related to drilling mud discharges has been attributed to Polycyclic Aromatic Hydrocarbons PAH content. This study addressed concerns related to the potential for. Comparative thyroidology: thyroid gland location and iodothyronine dynamics in Mozambique tilapia Oreochromis mossambicus Peters and common carp Cyprinus carpio L. In teleosts, the thyroid gland is mostly found in the subpharyngeal region.

However, in several species thyroid follicles are found in, for example, heart, head kidney and kidney. Such heterotopic thyroid follicles are active, and Such heterotopic thyroid follicles are active, and considered to work in concert with the subpharyngeal thyroid. In Mozambique tilapia Oreochromis mossambicus thyroid activity is, indeed, restricted to the subpharyngeal region; in common carp Cyprinus carpio the functional endocrine thyroid is associated with renal tissues.

Although the shape and size of carp subpharyngeal and renal follicles vary, the epithelial cell height of the thyrocytes and thyroxine immunoreactivity do not differ, which suggests that the activity of the carp subpharyngeal thyroid follicles is dormant.

Induction of sex reversal in Oreochromis mossambicus by diethylstilbestrol. Fry of 8—10 mm total length were fed diets containing 25, 50 and ppm of DES for Fry of 8—10 mm total length were fed diets containing 25, 50 and ppm of DES for 30 days in plastic pools; this was followed by 45—65 days rearing in fertilized cement cisterns where hormone-free diet was given.

The untreated control group had a higher proportion of males than females. No intersex or sterile individuals were observed among the steroid-treated fish. Related Topics. Follow Following.
