Abstract

One of the problems faced in blue swimming crab hatchery business is the reliance on the use of natural feed. This research aimed to study the effect of rotifer feed replacement by predigested artificial feed on survival rates, growth rates of the larval stages and to determine the best feeding period of predigest artificial feed 100% to replace rotifers. The study was conducted in May-June 2015 in a household scale hatchery location at Bojo Village, Mallusettasi District, Kabupaten of Barru. There were five replacements of rotifers by predigest artificial feed namely: A. Control (feeding with rotifer up to stadia zoea 4), B (feeding with rotifer up to stadia zoea 3), C (feeding with rotifer up to stadia zoea 2), D (feeding with rotifer only at stadia zoea 1), E (No feeding with rotifer). Predigest artificial feeds were fed for a rearing period of larvae in all treatments. The results showed that the survival of the blue crabs larvae that did not consume rotifers as a feed source were significantly lower than the crab larvae consuming rotifers. The larvae with no feeding rotifer survived only at stadia zoea-2 while those feeding with rotifers survived until zoea-4. The rate of stadia changes did not differ among treatments getting rotifers. Use of predigest artificial feed on crab hatchery can be an alternative to rotifers in the future. Feeding predigest 100% can be started at stadia zoea-2. Key words: blue swimming crab, Portunus pelagicus, larvae, rotifers, predigest artificial feed.

Abstract

In this study, the effects of alginate from Sargassum polycystum molecular reduction by thermal heating on DPPH anti radical scavenging activity were investigated. Raw alginate as the control treatment was heated at 140oC in a laboratory oven for different time courses 1.5, 4.5, and 7.5 hours. The assessment of molecular weight, UV-visible and FT-IR spectroscopic studies were applied. By heat treatment, molecular weight of polymer was decreased in a time-dependent manner, though there is no significant difference between 4.5 h and 7.5 h samples. The UV-visible spectroscopic studies pointed that there was a new absorption band between 250 and 290 nm in alginate heated treatments. The higher antiradical scavenging activity were reached from 1.5 h and 4.5 h treatments (19.83% and 20.07%). Interestingly, the antiradical scavenging activity of the longest heating treatment (7.5 h) was reduced (16.85%), similar to the raw alginate (17.89%). Prolonged heat treatments influenced the antioxidant activity and reduced the ability of donate electrons or hydrogen atoms to inactivate this radical action.

Abstract

The spermatozoa quality of goramy two days after sub-zero freezing was examined. The quality of spermatozoa examined included motility, viability, and abnormality. We aimed to determine the optimum concentration of glycerol protecting spermatozoa during preservation. We used 0%, 1%, 3%, 5%, 7%, and 9% of glycerol, respectively.  Sperms were diluted by the combination of glycerol and fish ringer (1 part of sperm + 3 part of solvent). The dilute sperms were then equiliberated at 4°C for 45 min, and were freezed at -34°C for two days. Thawing was then carried out at 30°C for 2 min. Based on Dunnet test, 5% of glycerol was the optimum concentration maintaining spermatozoa motility (75.95±4.76)%.Keywords: glycerol; Osphronemus goramy; spermatozoa motility, viability, and abnormality; sub-zero freezing

Abstract

Various designs of floating fish cages have been developed by the fishermen, both for applications on the rivers, reservoirs, coastal areas, offshore and lakes. In order to optimise the ecological use of Lake Rawapening as fish farming area, it is necessary to change the design of cages as well as farming practice. The development of design of floating net cage has been done using Stratified Double Net Cages (SDNC), and it is considered to be one of the best alternatives to solve the problem.  The aims of this study were to evaluate the application of Stratified Double Net Cages (SDNC) based on macrobenthic assemblages to assess the potential environmental impact caused by farming activities using SDNC. The results were compared to the reference areas, which were 1 (one) km away from the farming zones.This study was carried out at the ficinity areas of two SDNC. The cages were operated by fisherman groups of  Ngudi Makmur and Rukun Santosa, located on the water column of Lake Rawapening, close to Asinan District, Central Java. The results showed that the composition of species macrobenthic assemblages between farming sites and control sites were different both in number and compotition, indicating the initial stage of disturbance caused by organic enrichment due to farming actitivites. The study provides important implications for the arrangement of Stratified Double Net Cage (SDNC)  activities at Lake Rawapening, both in density and ordinate position in order to maintain the ecological function of this lake.

Abstract

The aim of this research was to evaluate whether the feeding levels in Litopenaeus vannamei nursery can be reduced without any adverse of the shrimp growth under bioflock conditions. There were 5 different reduced feeding levels as treatments in triplicates in this study ie. 10% reduction of the feeding level (A), 15% reduction of the feeding level (B), 20% reduction of the feeding level (C), 25% reduction of the feeding level (D), and no reduction of the feeding level (E; as control). Average daily gain (ADG) and water quality parameters were observed in the study. Results of the study showed that there were no significant differences (P>0.05) among all treatments with ranges of 0.11-0.19 g/day. It means that under bioflock conditions the feeding levels in the Litopenaeus vannamei nursery can be reduced up to 25% without any adverse in the growth performance.

Abstract

The effects of soybean meal (SBM) on the energy budget of red sea bream Pagrus major juveniles (3.2 g initial wet weight) were determined by supplementing  SBM in the diet at 0% (control diet), 16%, 24%, 32% and 39%, with the fishmeal content correspondingly reduced from 55% to 29%. Diets were made isoenergetic and isonitrogenous by changing the lipid and carbohydrate levels. Fish were fed to apparent satiation for 30 days in duplicates per diet (20 fish per replicate). Ammonia excretion and oxygen consumption were continuously measured during the growth trial, whereas digestibility after the termination of growth trial. Feed intake, body weight gain, and specific growth rate of fish increased to a peak at 24% SBM level, which again decreased as the SBM level was further increased. The apparent digestibility of energy was similar in all dietary treatments, while the digestible of dry matter increased with the SBM level. A lower proportion of energy intake as growth at 39% SBM level was attributed to the higher energy intake channeled to fecal ammonia.  This study suggested that the inclusion level of SBM in diets for red sea bream juveniles should be is optimal at the inclusion range 24–32%, thus correspondingly replacing the fishmeal content by 24–32%.

Abstract

Sargassum cristaefolium merupakan salah satu dari jenis rumput laut yang dapat digunakan sebagai feed suplement dan memiliki zat imunostimulan yang dapat meningkatkan sistem kekebalan tubuh ikan sehingga meningkat pula pertumbuhannya. Tujuan penelitian ini adalah mengetahui dosis penambahan tepung alga coklat (S. cristaefolium) dalam pakan yang menghasilkan laju pertumbuhan dan efisiensi pemanfaatan pakan terbaik untuk ikan nila salin (O. niloticus). Penelitian ini dilaksanakan pada bulan Mei-Juli 2017 di Laboratorium Pengembangan Wilayah Pantai (LPWP) Jepara. Ikan yang digunakan dalam penelitian adalah ikan nila salin dengan rerata bobot awal sebesar 6,6±0,23 g/ekor. Pakan uji yang digunakan yaitu pakan dengan penambahan tepung S. cristaefolium yang berbeda (0, 1, 2, dan 3%). Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan empat perlakuan dan tiga ulangan. Penelitian ini dilakuan selama 42 hari, data yang diperoleh meliputi total konsumsi pakan (TKP), efisiensi pemanfaatan pakan (EPP), rasio efisiensi protein (PER), laju pertumbuhan spesifik (SGR), dan kelulushidupan (SR). Perbedaan tingkat penambahan tepung S. cristaefolium pada pakan memberikan pengaruh nyata (P<0,05) terhadap TKP, EPP, PER dan SGR dan tidak berpengaruh nyata (P>0,05) terhadap kelulushidupan.  Kualitas air pada media pemeliharaan masih dalam kisaran yang layak untuk pemeliharaan ikan uji. Dosis terbaik penambahan S. Cristaefolium yang menghasilkan nilai tertinggi pada TKP (246,25 g), EPP (53,84%), PER (1,63%) dan SGR (2,01%/hari) adalah 2%. Sehingga dapat disimpulkan bahwa penambahan tepung S. cristaefolium pada dosis 2% merupakan dosis yang paling efektif menghasilkan nilai laju total konsumsi pakan (TKP), efisiensi pemanfaatan pakan (EPP), rasio efisiensi protein (PER) dan pertumbuhan spesifik (SGR) terbaik.
