Abstract

This research was conducted at Unit of business Freshwater Aquaculture (UPBAT) Pasuruan, East Java, on July – September 2015. The purpose of this study was to determine the fish hatchery techniques of Cyprinus carpio in UPBAT Pasuruan. Hatchery goldfish in UPBAT include aircraft maintenance, preparation for spawning tub, parent selection, breeding, seed maintenance and feeding. Results obtained are spawning carp be done naturally by mass system, using the parent goldfish namely 4 female parent and 8 male parent of a total holding in UPBAT. In one spawning produced ± 240,000 eggs, resulting in a year with three times the number of eggs obtained spawning ± 720,000 eggs. The fertilized eggs will hatch 2-3 days after spawning, spawning once the larvae thus obtained ± 236 128 ± 708 384 larvae in a year so the HR = 98.38%. Once spawning is obtained approximately 205 984 fish seed so that in one year earned approximately 617 952 fish seed which means SR = 87.23%. Feeding the form of natural silk worms do after the yolk will run out (± 3-4 days) at a dose of feeding as many as 3% of the body weight of larvae / day approximately 100 grams, to 236 128 larvae. As for the mains feed pellets was given at a dose of feeding 3% of the parent body weight / day 2 kg for the mains and feed on the seeds with a dose feeding 3% of the seed weight / day to 800 grams to 205 984 fish seed.

Abstract

Kerapu Macan (Epinephelus fuscoguttatus) memiliki habitat asli di perairan laut dan merupakan ikan karang. Penelitian ini dilaksanakan di unit usaha kelola benih unggul Desa Klatakan, Pecaron Kabupaten Situbondo Jawa Timur. Populasi penelitian ini menggunakan 3 bak pemeliharaan larva dan 20 bak kolam pakan alami. Teknik pengambilan sampel dengan cara langsung dilapangan. Hasil penelitian menunjukkan bahwa Larva D2-D30 kerapu macan diberi pakan jenis rotifer dengan kepadatan 3-10 individu/ml, Nauplius Artemia salina diberikan saat larva D 15 hingga D35 selanjutnya udang rebon diberikan pada saat larva D26-50. Dosis pemberian VIT C 1%. Dosis pemberian baik untuk rotifer dan naplius Artemia salina adalah 0,6 ppt. Nilai HR (Hatching rate) telur mencapai 80%. Tingkat kematian tertinggi pada hari D3 sebanyak 50 %.

Abstract

Perkembangan budidaya laut dari tahun ketahun terjadi peningkatan, usaha perikanan skala rumah tangga banyak berkembang di daerah pesisir Kabupaten Situbondo dikelola oleh pembudidaya ikan hanya atas dasar milik mereka sendiri modal dan pengalaman, tetapi tanpa mempertimbangkan keuangan aspek kelayakan bisnis dan konservasi lahan buidaya. Tujuan untuk mengetahui kelayakan usaha, volume dan nilai produksi budidaya kerapu cantang. Data primer dianalisis menggunakan analisis deskriptif dan analisis kelayakan bisnis melalui pendekatan kriteria investasi. Hasil penelitian menunjukkan bahwa Hasil yang didapatkan adalah BEP unit: 265.506.000 ekor, BEP harga : 42.657.325 / tahun, B/C Ratio: 1,30 dan Pay back period 2,1.

Abstract

The aims of this study was to determine the effect of the aquaponic system on the normalization of water quality for organic catfish cultivation, the survival rate of catfish and the growth of water spinach in the aquaponics system. The research method to be carried out is an experimental method using a completely randomized design (CRD) with different stocking densities, namely P1 (100 fish/m2), P2 (250 fish/m2), and P3 (500 fish/m2). The parameters measured were the water quality of the catfish culture media including NH3, NO2, NO3, pH, and dissolved oxygen, as well as the survival rate of catfish and kale plant growth (plant height, number of leaves, and leaf width). The results showed that rearing catfish with an aquaponic system with Kangkung plants could stabilize water quality. Value of water quality NH3 (0 – 0.1 ppm), NO2 (0 – 0.881 ppm), NO3 (0 – 1.443 ppm), pH (6 – 7.8), and dissolved oxygen (4.5 – 6.2 ppm). The survival rate was P1 (95.2%), P2 (94.3%), P3 (89.6%). The best growth of kale was found in the P3 treatment, namely plant height 37.2 cm, leaf width 2.5 cm, and number of leaves 24 strands. The results showed that the water quality was relatively stable. The higher the stocking rate, the lower the survival rate of catfish, on the other hand, the higher the stocking density, the better the growth of kale plants.

Abstract

Natural feed has a very important role in supporting the success of aquaculture. The availability of natural feed is a key factor in the seed / fry phase, where at that phase the fish are still unable to consume additional feed, namely pellet feed. The objectives of this activity are: (1) Introducing Artemia, Improving the entrepreneurial spirit and entrepreneurial motivation, (3) Increasing the knowledge and abilities of SMK Ibrahimy 1 Sukorejo students in terms of decapsulation and artemia culture. This activity targets the fishery students of SMK Ibrahimy 1 Sukorejo, Department of Agribusiness, Brackishwater and Marine Fisheries. Service activities are carried out using lecture and demonstration/practice methods. Evaluation was carried out on the ability of participants to practice artemia decapsulation and artemia culture, indicators of the success of this practice are theoretical and practical knowledge of Artemia sp culture. The success of this activity can be seen from the very high enthusiasm of students and the increasing knowledge of students about the decapsulation of Artemia sp. The obstacle that is used as an evaluation in this activity is that several additional tools are still needed to maximize the decapsulation practice of Artemia sp.
