Phospholipids are known to play a significant role in lipid transport in crustaceans. LYSOFORTE™ is a bio-emulsifier enriched with lysophospholipids used in animal feeds to improve the digestion and absorption of fat. Objective of the current study was to evaluate the growth promoting effect and fish oil sparing effect of LYSOFORTE™ Dry in Tra Catfish (Pangasianodon hypophthalmus) diets. This study comprised four treatment groups: positive control diet (T1) with 1% fish oil, negative control diet (with 1% less fish oil) (T2), negative control diet + LYSOFORTE™ Dry (0.05%) (T3) and negative control diet + LYSOFORTE™ Dry (0.10%) (T4). Each treatment group comprised 3 replicates with 50 juveniles/replicate. Negative control treatments with LYSOFORTE at 0.05% and 0.10% improved the average body weight gain by 16.08g and 25.74g (p>0.05) with a corresponding FCR improvement of 1 point and 11 points respectively. Specific growth rate improved by 0.18%/day (0.05% LYSOFORTE™ Dry) and 0.28%/day (0.1% LYSOFORTE™ Dry). Survival percentage also improved in the negative control diets supplemented with LYSOFORTE™ Dry by 6.67%. Protein efficiency ratio increased by 0.22 (T3) and 0.11 (T4) whereas protein retention improved by 4.89% (T3) and 3.63% (T4) with respect to the negative control diet (T2). Lipid retention increased with the use of LYSOFORTE™ Dry: 27% for T3 and 37% for T4 (P<0.05). Moreover, fish fed with negative control diet with 0.10% of LYSOFORTE™ Dry showed on par performance with those fed on the positive control diet. The results suggested the potential of formulating cat fish diets with less fish oil using LYSOFORTE™ Dry

Aquaculture is undergoing a rapid phase of expansion as never before. Like any food-producing sector, there are environmental, social and economic implications of aquaculture development as well. It is imperative to identify actions and potential for promoting business ideas behind aquaculture systems that are in harmony with the environment even as this sector increases its contribution to food security and socio-economic welfare. This paper presents an in-depth analysis of the actual and potential role of aquaculture in supporting blue growth and achieving sustainable development goals. It emerges from the synthesis of information so generated that: 1) Aquaculture’s key role in sustainable development goals deserves to be adequately documented, backed by facts and figures, 2) Aquaculture’s contribution to each of the goals is qualitatively and quantitatively different, 3) Aquaculture is a diverse activity and, therefore, its impacts, especially from an environmental perspective, cannot be generalized across the whole sector, as these will vary with species, farming methods, environmental conditions at the location and the local socio-economic scenario. With its projected role in food security the aquaculture will continue to develop. However, this will be possible through scientific solutions focused on sustainability by informing best practices. As marine aquaculture moves further out to the sea new knowledge will be needed to understand environmental impacts and to support new farming systems. Similarly, data will also be needed to adapt aquaculture methods to changing climate. A systems approach to managing aquaculture is the way forward, a showcase of which is integrated multi-trophic aquaculture. The progress of aquaculture in meeting the sustainable development goals will require a monitoring mechanism that the relevant agencies need to put in place.

A part of S. tranquebarica crablet offspring produced from larvae rearing often grows faster than the others. The research aimed to monitor larvae development and compared the growth between fast and slow growth crablet offspring. Hatched larvae reared until crablet stage with production 4848 individual. 600 individual were weighted and measured carapace width. The data figured as a normal distribution curve. 700 ind. of fast growth crablet with carapace width 15.2+1.29 mm and body weight 0.55+0.15 g/ind. were selected. The others 700 individual slow growth crablet, carapace width 8.88+3.11 mm and body weight 0.14+0.08 g/individual were selected also. These crablet stocked in four pond compartments each size of 500 m2 (350 ind./500 m2). Crablet growth was monitored monthly. After five months cultured, the fast growth crablet attained 185.7+38.7 g/ind. and significantly different (P<0.05) with the slow growth crablet 156.94+15.30 g/ind. The first female mature gonadal stage with weight 205.2+0.3g and carapace width 116.7+0.7mm was obtained from the fast growth crablet group after fourth months cultured. That female mature gonadal was spawned after 27 days incubated in the hatchery. Fast growth crablet is concluded more effective for the broodstock candidate in mud crab hatchery.

Publisher : Indonesian Aquaculture Society (MAI)

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.

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%.

Dosage Optimization of Artificial Digestive Enzymes in Feed to Improve The Digestibility and Growth of Osphronemus gourami Bokau, Rietje J.M; Febriani, Dian; Indariyanti, Nur; Rakhmawati, Rakhmawati

One of the obstacles often encountered in the cultivation of gourami is a relatively slow rate of growth compared with other freshwater fishes. This slow growth is partly due to the incomplete and unbalanced nutritional content and the low ability of the fish to digest a certain type of feed materials. The ability to digest fish feed types depends on the quality and quantity of feed and enzymes present in the digestive tract. The enzymes released by the glands in the gut have the function to digest food elements. Among the enzymes involved in digestion are amylase, protease, lipase, cellulase, pectinase, and pullulanase. To improve digestion, the use of artificial enzymes in certain doses is combined with natural food such as papaya to optimize the dose of artificial enzymes. The use of papaya is already widely used as a food supplement, especially in the gourami grow-out culture. Aside from being natural food, papaya leaves can also serve as a natural source of digestive enzymes. The objective of this study is to determine the optimal dose of artificial enzymes added to feed which can improve the digestibility and growth of gourami. In this study, treatments of artificial feeding of gourami are used with the addition of artificial enzymes amounting to 1% (A), 2% (B), 3% (C), papaya leaves and pellets (D), and pellets alone (E). Results after two months rearing showed that the digestibility of feed supplemented with natural enzymes in papaya (papain) can be further improve optimized by the addition of artificial digestive enzymes in a dose of 3% of the weight of the feed. Fish of this treatment group showed faster growth compared with other treatments.

This study was conducted to determine the condition of immunological response of and the presence of bacterial diseases in Anabas Testudineus fish was transported from pond culture towards Segiri Market. Transport system carried out by the fishmonger supposed to influence the health conditions of fish as well as the presence of bacteria on the fish's body. The sample was 30 fish from Muara Kaman pond and Markets Segiri as a fish marketing. Some parameters were observed among others: changes in swimming behavior, pathology anatomy organs, aemotology and inventory of bacterial diseases. The results showed that the samples of fish from the pond aquaculture generally have normal conditions of organ anatomy, symptom behavior swim also normally, otherwise fish from marketed in the Market Segiri, as much as 60% of fish have abnormal behavior of swimming, 73% have pathology on external anatomy and 53% fish have abnormalities in organs. Results of the isolation and identification of bacterial disease found that there are 5 types of bacteria Aeromonas, Pseudomonas, Staphyllococcus, Streptococcus and Basillus, and only bacteria Staphyllococcus and Basillus not found in fish pond aquaculture origin. The health condition of the fish pond aquaculture origin betook better, judging from the hemoglobin, hematocrit, total leukocyte and total erythrocyte that is within the normal range. While the blood picture fish from Segiri market is generally higher in all parameters that indicate health problems. It can be concluded that the transport system carried out by the wet etching fishmonger effect on the occurrence of abnormalities in behavioral symptoms, anatomic pathology outer and inner organs, the presence of bacterial disease and the decline in fish health conditions.Keywords : Betok fish, bacterial, transportation

Aquaculture technology of abalone is commonly using traditional method in which natural resources are used as the primary inputs. Recent studies however showed that light intensity could also enhance the apetite of abalone despite of food types and concentrations. This study was emphasized at investigating light intensity individually or sinergistically with food types and concentrations in enhance growth rates of abalone. A randomised complete factorial design with three different treatments of light intensities (0 luxes, 250 luxes, and 500 Luxes), two levels of food resources (Gracillaria licheinodes and Ulva fasciata), and three levels of food percentage (20%, 22.5% and 25%) for three replicates were held. The result showed that light intensity, food types and food concentration significantly affected the growth rates of abalone. Light intensity of 250 luxes with food type of Ulva fasciata at the level concentration of 22.5% resulted on the highest growth rate, both at laboratory level and in the field (sea). The highest growth rate of abalone was found in the outdoor system, maximum ages of 8.5 years, maximum length of 114 mm, and maximum weight of 44 g.

Lobster, one of the high values sea-cage culture commodities in Indonesia, has some specific requirements of life environment. However, there haven’t been any studies that specifically identify these potential sites. Until today it is only 3.50 ha out of 526.86 Ha of these that have been utilized. This study aims to map the marine suitability environment for lobster cultivation in Ekas Bay, using remote sensing and GIS approaches. The requirement parameters maps for lobster marine suitability, includes oxygen levels (DO), nutrition, salinity, temperature, depthness, pH, and water clearence which are able to be extracted from Landsat 8 imagery. Using GIS, a model was developed to integrate those maps with marine environment secondary maps, water laboratory analysis, and other information from interview result with the local farmer’s. The result shows that lobsters live in the environment which has the temperature between 200 to 250C and at the water depth of reaching 100 m. Laboratory analysis result presents the pH value of above 7 in average, DO ranges from 5-8 ppm, and salinity level from 28 to 35 ppt. In summary, the integration of remote sensing and GIS approaches are able to identify the common parameter that support the environment suitability for lobsters which is then formulated as a standard of marine environment suitability mapping.
