Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh penyapihan pakan mikroenkapsulasi ekstrak kasar maggot pada umur larva nila (Oreochromis niloticus) yang berbeda serta menentukan waktu penyapihan yang tepat. Analisis yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan 4 perlakuan (kontrol atau tanpa penyapihan, penyapihan pada umur 9, 14 dan 19 hari) dan 4 ulangan. Variabel yang diamati yaitu, pertumbuhan mutlak (panjang dan berat), laju pertumbuhan spesifik (SGR) dan sintasan (SR). Hasil penelitian menunjukan pertumbuhan mutlak panjang berkisar 7.15 - 8.65 mm, pertumbuhan mutlak berat berkisar 0.046 - 0.084 g, SGR berkisar 5.633 - 7.352 % dan SR berkisar 64 - 76 %. Waktu penyapihan pakan berpengaruh terhadap pertumbuhan dan sintasan larva ikan nila (p0,05). Waktu penyapihan pakan terbaik terdapat pada usia larva 9 hari.

Abstract

Sungai merupakan salah satu sumber daya perairan umum yang bersifat open access, khususnya masyarakat yang bergantung pada sumber daya tersebut. Namun pemanfaatannya terkadang tidak memperhatikan keberlanjutan sumber daya yang ada. Meningkatnya intensitas pemanfaatan sumberdaya perikanan akan memberikan ancaman terhadap kelestariannya. Pokmaswas Jenggala Saba Kali memiliki peranan strategis dalam pemanfaatan, pengelolaan dan pelestarian sumberdaya daya perairan dan perikanan di Sungai Klawing. Peningkatan peran strategis pokmaswas ditingkatkan melalui alih teknologi pengelolaan sumberdaya perairan dan restocking benih. Anggota Pokmaswas Jenggala Saba Kali secara umum sudah memahami konsep pengelolaan sumberdaya perairan dan perikanan berbasis masyarakat. Hal ini tercermin dari jawaban-jawaban atas pertanyaan dalam kuisioner yang mencapai nilai 70 pada saat pre test dan nilai 90 saat post test. Akan tetapi anggota pokmaswas masih belum paham akan penting dan perlunya peningkatan kapasitas sumberdaya alam. Pelatihan pembuatan alata tangkap selektif Restocking benih ikan sebanyak 2600 ekor dari berbagai macam ukuran ini merupakan upaya mendukung keberlanjutan pengelolaan sumberdaya perairan yang lestari baik ditinjau secara ekologi, social dan ekonomi di masa mendatang untuk peningkatan kesejahteraan atau pendapatan masyarakat.

Abstract

High mortality in the larvae stage was a major problem in fish hatchery efforts. Efforts that can be done through the hormonal stimulation with the utilization of thyroxine hormone. The purposes of this research was to determine the effect of immersing eggs in a solvent of thyroxine hormone at different doses on hatchability, growth and survival nilem fish larvae (Osteochilus hasseltii). The research method use a complete randomized design (RAL). Treatments in this research were A (control), B (0.05 mg / L), C (0.10 mg / L), D (0.15 mg / L). The research variables observed were hatchery, an absolute long-term growth, relative long-term growth and the survival. The results of this research showed that the soaking of eggs in thyroxine hormone at different doses had no significant effected on hatchability (P> 0.05) but had a significant effected on growth, and survival of nilem fish larvae (P

Abstract

Guppy fish is one of the ornamental fish commodities that is quite in demand, because of its various types with beautiful colors. The purpose of this study was to determine the effect of adding carrot flour in commercial feed to improve the color quality of guppy fish and the best dose. The test fish used were male guppy fish strain HB red with sizes ranging from 2–3 cm. This research was conducted using an experimental design, namely a Completely Randomized Design (CRD) consisting of five treatments (commercial feed enriched with carrot flour as much as 0%; 2,5%; 5%; 7,5%; 10%) and three replications. The results showed that the addition of a dose of carrot flour had an effect on improving the color quality of guppies and the highest color quality improvement was found in treatment 4 (10% 2 carrot flour) with a chroma value of 3.97±0,18c , while in the control treatment, treatment 1, treatment 2, and treatment 3 got chroma values of 1.26±0.12a, 1.28±0.03a, 1.71±0.06a, 2.72±0.31b. Survival showed the results were not significantly different, that is 100%. Water quality includes an average temperature of 25,5– 26,6?C, pH 7–8, DO 6,7–7,8 mg/L. Key words : HB Red; Carotene; Chroma value; Survival
