Abstract

Blacktail Zebra fish (Dascyllus melanurus) is more caught the sea by fishermen. There are several limitations which are lower growth and feet effisincy trought the natural  habitat. Hence, an optimal feed combination is consideret  to be provided during fish rearing to increase their growth.  One of ideas was to use probiotic, which is bacteria that are able to decompose organic materials to change toxic compounds is valauable matter  to the environment. For instance, ammonia and nitrite can be converted into free ammonium. The additional in an artificial feed is exfected to gain aquaculture activities. The study was conducted for 56 days from August to October 2019 in Wetlab Kastela  FPK of Khairun University. Experiment  and four treatments were applied using Filling Randomized Design (RAL). The result shows that different additional probiotic effected the growth and survival rate of Blacktail zebra fish. The highest was found in probio7 15 ml/kg feed,  which gave 0,88g of total growth’; and the lowest was 0,27g which was found in the treatment A ((control)/ Water quality was checked  weekly and in normal condition for the growth of the growth of blacktail zebra fish.

Abstract

The research was carried out from April to December 2022 at the Integrated Laboratory at Khairun University. The research design consisted of 4 treatments that were tried, namely: Treatment A: Prawns were given 25% maggot flour + 25% prawn head flour, Treatment B: Prawns were given 20% maggot flour + 30% prawn head flour, Treatment C: Prawns were given 30% maggot flour + 20% shrimp head meal and Treatment D: Giant prawns were fed commercial feed (control). The research variables consisted of feed proximate test, feces test to determine feed digestibility of giant prawns, specific growth rate (LPS), absolute weight growth and survival rate. Based on the results of the feed proximate test showed that treatment D gave the best results by looking at the average feed protein content of 32.51%, the digestibility value was directly proportional to the feed protein value content in treatment D of 23.06%. The specific growth rate (LPS) during maintenance showed that treatment D gave the best treatment with an average growth yield of 0.684%, the best absolute growth was in treatment D with an average value of 0.120 gr. Based on the results of this study it can be concluded that the results of the proximate test of the feed showed that treatment D gave the best results as seen from the average feed protein content of 32.51%, while the digestibility value was directly proportional to the feed protein content in treatment D with an average of 23, 06%.

Abstract

Biotechnology is used to apply technology to the C/N ratio by stimulating the activities of heterotrophic microorganisms, which derive food from carbon and nitrogen substrates in a certain ratio. The goal of this research was to see how the optimal carbon-nitrogen ratio affected water quality and floc volume in white leg shrimp (Litopenaeus vannamei) farming. This study took place in the UPT Integrated Laboratory Unkhair in Ternate City in July and August 2021. A fully randomized design (CRD) with four treatments and three replications was used in this investigation. Different C/N ratios had an effect on ammonia, nitrite, nitrate, floc volume, and feed conversion ratio, according to the research. The water quality parameters are still suitable for white leg shrimp cultivation. In white leg shrimp culture, the addition of C-organic molasses (different C/N ratios) was able to reduce the concentrations of (NH3), (NO2), and (NO3), and also greatly increase the flock volume and streamline the feed conversion ratio.Keywords:C/N RatioVannameiWastewaterBiofloc

Abstract

Provinsi Maluku Utara merupakan daerah kepulauan dengan potensi budidaya perikanan yang sangat besar. Salah satu daerah yang berpotensi adalah Desa Kastela Kecamatan Ternate Selatan, Kota Ternate, Maluku Utara. Pengembangan budidaya ikan dengan sistem bioflok telah dikembangkan di Laboratorium Basah Fakultas Perikanan dan Ilmu Kelautan Universitas Khairun yang berlokasi Kelurahan Kastela, Kota Ternate. Kegiatan bina desa ini bertujuan untuk meningkatkan pengetahuan masyarakat mengenai potensi budidaya dengan memanfaatkan inovasi budidaya sistem bioflok sebagai upaya membangun bisnis perikanan budidaya di Kelurahan Kastela. Tahapan kegiatan bina desa ini meliputi: persiapan, pelaksanaan kegiatan, dan analisis data. Tahap persiapan yang dilakukan adalah melengkapi persyaratan administrasi izin dengan pemerintah Desa Kastela. Pelaksaanaan kegiatan untuk meningkatkan pengetahuan masyarakat mengenai potensi budidaya dengan memanfaatkan inovasi budidaya sistem bioflok dilakukan dengan metode ceramah (pemberian materi budidaya ikan). Untuk mengetahui keberhasilan kegiatan dilakukan tes berupa kuesioner sebelum dan setelah kegiatan. Materi yang diberikan mengenai potensi dan peluang perikanan budidaya, pengenalan budidaya sistem bioflok, manajemen kualitas air budidaya, serta manajemen kesehatan ikan. Hasil kegiatan ini menunjukkan adanya peningkatan pengetahuan peserta bina desa sebesar 64%. Dengan demikian, hasil kegiatan ini diharapkan mampu mendorong pengembangan budidaya perikanan di Kelurahan Kastela, Kota Ternate, Maluku Utara.
