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.

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.

Cultivation of Kappaphycus alvarezii has been carried out by inverted pyramid method in the deep water of Saparua Bay. This study aims to analyze the daily growth rates, biomass productions and carrageenan yields of the green and brown strain of K. alvarezii with different depth of water by inverted pyramid method in deep seawaters. K. alvarezii with an initial weight of 100 g were planted successively at the depths of 1, 3, 5, 7 and 9 m during four growing seasons that last for 49 days in every season. The results showed that the highest growth rate and biomass production were on green strain at 1 m depth and brown strain at 3 m depth which were 4.18% and 749.29 g/m2 then 4.19% and 754.51 g/m2, respectively. While the highest carrageenan yield was on the green and brown strain at 9 m depth which were 16.53% and 14.85%, respectively. The carrageenan yields gradually increase with the increasing of water depths which contradict to growth rate and biomass production that showed the better results at lower depths (1 and 3 m). In conclusion, seaweed cultivation in deep waters has a positive impact on carrageenan yields in line with the increasing depths while the growth rate and the biomass production can be achieved higher at the lower depth.

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.

The goal of feed enrichment with amylolytic Lactic Acid Bacteria (LAB) was to get an optimal feed formula in stimulating the growth of freshwater crayfish (Cherax quadricarinatus). The research design used a completely randomized block design, which consists of 2 groups (Group I = probiotic HS7 with inoculum density 108 and Group II = probiotic HS7 with density 1010). Each group were given 4 different treatment (Feed A = protein 50%-carbohydrate 20%; Feed B= protein 40%-carbohydrate 30%; Feed C= protein 30%-carbohydrate 40%; and Feed D= protein 20%-carbohydrate 50%), with 2 repetition. The parameter observed in this study was daily growth rate and absolute growth. The result showed that Feed C, composed by protein 30%-carbohydrate 40% with LAB enrichment and inoculum density of 108 gives the best growth, with daily growth rate of ± 0.22-0.23 % each day and absolute growth of ± 13.10-13.20 gram in 75 days.

Brackish water vannamei shrimp in the village of Keburuhan, Ngombol District of Purworejo Regency is one of the shrimp aquaculture activities developed since 2010. Shrimp farming enteprises is done by local communities which use the sandy soil coated plastic sheet with an area of 1000-4500 m2. There is a positive impact by increasing the income and welfare of farmers, but give negative effects in decline of surrounding pond environment. The shrimp farmers mostly disposed of wastewater directly into the sewers or the surrounding area. The wastewater of vannamei shrimp culture contains of uneaten feed and plankton that can be utilized to grow milkfish. The aim of this study was to determine the growth and feeding preferences for milkfish culture in wastewater reservoir of vannamei culture. The study was conducted from January to April 2017 by rearing of milkfish in earthen ponds of shrimp culture in wastewater reservoir. Wastes consist of feces and uneaten feed during shrimp rearing were siphoned and flowed into ponds wastewater reservoir. Milkfish juvenile with body length ranges from 9.3 to 9.7 cm and weight ranges from 3.4 to 6.9 g was introduced into three earthen ponds of 600 m2 each, with density of 6 individual/m2 in triplicate for 70 days. During the study, milkfish juvenile were not fed, but obtained wastewater from shrimp culture ponds. The wastewater from the shrimp ponds was siphoned and piped into a waste reservoir ponds every 3 days until shrimp harvesting. Fish samples of each pond as much as 40 individuals were taken biweekly and then measured the length and weight. Fish stomach was dissected and then digestive tract was taken to observe the species of plankton consumed. The results showed that milkfish could grow well in wastewater reservoir of shrimp culture. The average daily growth rate of length and weight of milkfish reached approximately 0.11 cm/day and 0.34 g/day, respectively. The length weight relationship of milkfish showed allometric growth pattern. The food type found in the intestinal was dominated by phytoplankton. Feed was dominated by genera of phytoplankton, which reach more than 99%. The most dominant of phytoplankton were Scenedesmus sp. (34.7%), then Crucigenia sp. (20.1%), followed by Cyclotella sp. (14.6%), and Clamydomonas sp. (7.5%) next Microcystis sp. (6.7%), while the other genera less than 4.2%. Further research is needed to determine the optimum density of milkfish to utilize wastewater of shrimp culture.

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.
