Abstract

The selection of planktons as live feed for milkfish larvae is a vital tool to meet the natural character as herbivorous species and to fulfill the needs for nutritious food for fish larval growth and survival. Phytoplankton Nannochloropsis sp. and zooplankton rotifer (Brachionus sp.) were two-selected plankton used as the main food source for the milkfish larvae. We performed this study in two times larval culture batch with four observations of tanks as replication. The results showed that we nourished both targeted planktons as larval food, regarding the positive impacts on larval growth (12±1,37 mm of total length, 7±4.89 mg of body weight) and a high survival rate (65.93?77.70%) achieved at the end of the culture period. Plankton diversity analysis presented that Class of rotifer (Monogononta) and Nannochloropsis sp. (Eustigmatophyceae) were both counted as the most dominant plankton group found in the rearing media, showing a decent sign of food supply for fish in rearing water column. The total number of planktons was high and had the tendency to follow the concentration of selected planktons over the culture period in the controlled water.

Abstract

Ikan kerapu sunu Plectropomus leopardus merupakan komoditas perikanan laut yang bernilai ekonomis tinggi dengan harga yang mahal. Benih telah dapat diproduksi mulai dipasarkan ukuran 3,0 cm, proses transportasi sangat diperlukan mengingat konsumen yang memerlukan benih kerapu sunu untuk usaha pendederan atau budidaya yang tempatnya jauh dari sumber benih. Penelitian ini bertujuan mengetahui sampai berapa lama waktu tempuh yang dapat menghasilkan benih dengan kelangsungan hidup tinggi dan kondisi ikan sehat. Transportasi benih ikan kerapu sunu dilakukan dengan sistem tertutup, dengan menggunakan mobil bergerak, setelah 6 jam perjalanan oksigen dalam kantong  plastik diganti, kemudian dikemas kembali seperti semula untuk melanjutkan perjalanan sesuai perlakuan. Benih ikan kerapu sunu yang digunakan ukuran 3,15±0,54 cm, dengan kepadatan 250 ekor per bok. Penelitian menggunakan   rancangan acak lengkap dengan lima perlakuan dan tiga kali ulangan,  dengan  perlakuan beda waktu transportasi: A.12 jam; B. 16 jam; C.20 jam; D. 24 jam dan E. 30 jam. Hasil menunjukan lama waktu transportasi pada perlakuan 12 jam hingga 24 jam  tidak berbeda nyata menghasilkan kelangsungan hidup 98,0 – 100%   tetapi berbeda nyata (P<0,05) dengan tranportasi selama 30 jam dengan kelangsungan hidup 79,9%.

Abstract

Market price of red emperor snapper Lutjanus sebae is often determined by its color performance. Adding beta-carotene on a fish diet would possibly escalate red pigmentation. Oil from a red fruit (Pandanus conoideus, Lam) known as potential beta-carotene source was used as a supplement diets. The dosage of 10, 5, and 0 ml were added to every kg of pellet as the treatment. Three hundred seeds with initial average length of 8.43±0.9 cm and body weight of 13.22±3.9 g were stocked in each of three unit fiberglass tank of 4 m3 seawater (salinity of 33-34). Experiment was conducted during three-month periods. Feeding frequency was twice a day with dosage of 3% of biomass. Monthly monitoring was done to measure the growth rate. Color performance was taken by digital photography at the end of observation and analyzed by conversion methods of color gradation using “Microsoft Adobe Photoshop-8”program. Carotene contents in the diets and fish body was examined. Fed effectivity values were observed by analysis of feed conversion ratio (FCR) and water quality that observed every 3 days. The results showed that the Pandanus conoideus oil as beta-carotene source had a significant role in increasing performance of red emperor snapper color i.e. brighten in red color. Ten ml dosage of Pandanus conoideus oil gave the best color and growth performance with 17.99 cm and 143.10 g for total length and body weight respectively, with 95.67% survival rate.Keywords: Beta-carotene, Color Performance, Red emperor snapper, Red fruit oil.

Abstract

The milkfish (Chanos chanos Forsskal) seed quality is an important factor for supporting the fisheries industrialization program . The egg fertility and larval rearing management are two main factors to improve the quality of the seed. The aim of this research was to obtain the information about those two indicators on milkfish larvae, reared in different media. About 100,000 eggs were located in 6 units of the outdoor concrete tank with volume of 6 m3. Larvae were reared due to the rearing standard procedure while the feeding management was adapted during larvae development. Two different treatments in larval rearing medium were with and without the addition of molasses, subsequently in triple trials. This study started from hatching day (0 DAH) until the end of larval rearing period (16-18 DAH). The growth parameters such as vertebrae analyses and survival were taken in the end of research periods, while protease assessment was analyzed every day using tyrosine and casein standard methods. The results showed  that  the molasses addition produced a higher growth (TL 12.95±0.87 mm) and survival rate (87.66±1.52%), better vertebral performance (44-45 segments), and higher protease activity (0.1392-0.3863 U/ml/min) than without molasses addition. The results indicated that molasses addition in larvae rearing medium improved the larvae quality. Keywords: Protease enzime activity,milkfish seeds, molasses, vertebrae
