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

Shrimp Waste Hydrolyzate (SWH) /Shrimp Soluble Extract (SSE) is a product produced from the enzymatic process of shrimp waste. SWH contains essential and non-essential amino acids which useful for fish. This study aimed to determine effect of SWH on the growth and total production of catfish. The parameters observed were average growth rate, specific growth rate (SGR), food conversion ratio (FCR), protein efficiency ratio (PER), total production and length weight relationship from beginning until the end of rearing period. Growth performance was observed by calculating average growth rate and SGR of catfish. The results of this study showed that oral administration of SWH significantly increased SGR of catfish length at 4th sampling period with value 1.54% body length/day. Administration of SWH did not affect on the AGR, FCR, PER and total production. The growth pattern of catfish is negative allometric.

Abstract

Hatchery is one of important factors to maximize shrimp production. One of supporting factorsis the availability of qualified natural foodsin sufficient quantities.The aim of this study was to know the addition effect of extract Sargassum to culture medium for population growth of Chaetoceros gracilis. Culture medium  used for microalgae C. grasilis was a 12 liter jar with density of 105 cell/mL. The Sargassum extract was obtained by processing Sargassum  waste through anaerob fermentation, then was extractedand considered as liquid organic fertilizer. Tested treatment was A = 0 ppm (without Sargassum extract), B = 10 ppm of Sargassumextract, C = 20 ppm of Sargassumextract andD =30 ppm of Sargassumextract for three replications. It was found that the population density of C. gracilis increased and the highest algae density occurred in treatmentD on day5, followed with C, B and A, which were 353,433 cell/mL, 336,833 cell/mL,308,867 cell/mL and 244,433 cell/mL. This illustrates that the addition of high doses has affected the population density of microalgae C.gracilis.

Abstract

The development of sustainable and economically sound practical diet in the coming years will depend on the reduction of fish meal and the increased inclusion of sustainable protein sources. Over the years, our laboratory has systematically reduced the inclusion levels of fish meal and other animal protein sources by using a range of alternative plant-protein sources. These diets may be further improved through the use of specialized proteins, supplements for limiting amino acids, enzyme and attractants. Good success has been seen with corn protein concentrates, advanced processing products of soybean meal, such as soy protein concentrates and advanced soy product (enzyme treated or fermented soy). Based on the results of our research, the proportion of animal meal can be reduced to 12 % in our current formulations without any detrimental effects on pompano performance and nutrient retention. In addition, the use of fermented soy or the combination of enzyme-treated soy with proper inclusion level of squid hydrolysates as an attractant has proven to improve the functional properties of SBM and lead to better liver and intestine condition of pompano. Considering the sizeable body of knowledge concerning nutrition for Florida pompano, all information taken from this species could be used as the starting point to develop better feed formulations for Silver pompano production in Indonesia.

Abstract

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.

Abstract

This trial was aimed to evaluate the effect different dossage of cinnamomum leaves (Cinnamomum burmanni) supplementation on the growth performance and survival rate of tilapia  (Oreochromis niloticus). A 30-day feeding trial was conducted in 12 aquaria with water system. Ten fish with average body weight of 100 g were reared in 60 x 35 x 30 cm3 of aquarium. Fish were randomly selected and stocked in each aquarium. The experiment was designed according to completely random design with three treatments and three replicates in each treatment. Experimental diets were prepared as dry pellet with Cinnamomum burmanni leaves of 0,25%, 0,5%,1,0% respectively, for 30 days. Fish were fed with experimental diets three times daily at satiation level.  Result of the experiment showed that addition of 0,25%, 0,5%, 1,0% cinnamomum leaves (Cinnamomum burmanni) gave spesific growth rate (SGR) 2,55±0,34%a, 2.15±0.25%b and 2.21 ± 0.16%a respectively; feed conversion ratio (FCR) 1,29±0,24a, 1,68±0,07%b, and 1,50±0,18%a respectively and survival rate (SR) all treatment were 100± 0,00%. If compared to control (SGR 1.87 ± 0.22%a, FCR 1.83±0.15%a and SR 100± 0,00%a), it was concluded that cinnamomum leaves dietary gave a better result, especially the addition of 0,25% cinnamomum leaves gave a significant increase of growth and feed convertion of tilapia (Oreochromis niloticus).

Abstract

In this study, the effects of oral administration of probiotic Bacillus sp. D2.2 and prebiotic from sweet potato extract on growth performance and resistance against Vibrio harveyi in Pacific white shrimp (Litopenaeus vannamei) were investigated. During 32-day feeding experiment, 360 individuals of Pacific white shrimp (PL15) with initial weight of 0.02 ± 0.002 g were fed with basal diet as control (A); supplemented with 6% probiotic and 0% prebiotic (B); 6% probiotic and 2% prebiotic (C); 6% probiotic and 4% prebiotic (D). At the end of feeding trial, weight gain (WG), average daily growth (ADG), feed conversion ratio (FCR), and survival rate (SR) were assessed. WG, ADG and FCR of the shrimp were significantly better in treatment D than those of the shrimp in other treatments. Control and treatment D as the best feeding trial were selected for challenge test with infectious V. harveyi. Survival rate and mean time to death (MTD) of the shrimp fed the supplemented diet were not significantly different (P>0.05) to the control. Infection levels in shrimp were evaluated using morphological scoring methods. Infection levels of V. harveyi in shrimp fed the diet were lower compared to the control.

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

High density is one of the common consequences of intensive shrimp culture. High density can induce stress on the shrimp. Nonetheless, stress is not always harmful. In limited period, stress can trigger metabolism process and the hormonal system of the body. This study aimed to determine how high-density rearing causes stress on juvenile shrimp. The experiment consisted of three different density treatments, 60, 90 and 120 tiger prawn juveniles/m2  with two different weight groups,  3 to 10 g,  and 11 to 16g as test animals. Each treatment with 3 replications, and 2 stocks were provided for treatment A, B, and C respectively (the stock was prepared to substitute the test animals at hemolymph sampling). Total Haemocyte Count (THC) was the main parameter used as a reference in assessing the response of tiger prawn juveniles to hight density. Based on the 3 treatments densities tested, the results showed that THC of the juvenile tiger prawns reared at 3 densities increased up to 24 h observation and decreased at 36 h observation. In fact, THC of the shrimp at the highest rearing density of 120 juveniles/m2 increased, which is one of the alleged treatment of tiger prawn juveniles tried to increase the tiger  prawns body defence. But the decline in THC was observed in the lowest rearing density of 60 shrimps/m2, in which the treatment did not cause stress on the tiger prawns  in the lower weight group of 5 to10g (treatment A). In contrast, THC of the tiger prawn  in the medium and highest rearing density (treatment B and C) drastically declined due to stress on tiger prawn juvenile and led to the tiger prawn  dead.  However, it is assumed that the tiger prawn juvenile that can adapt to the stressful condition, stress may become a stimulus that can trigger moulting, which is olso known as an indicator of growth.
