This study aimed to evaluate the growth and yield of carrageenan from Kappaphycus alvarezii (Doty) which were cultured at different depths of water. The study lasted for 49 days, using two strains (green and brown), three initial weights (50, 100, 150 g), and five levels of depth (1, 2½, 4, 5½, 7 m). The results showed significant differences between growth rate and yield of carrageenan on the three treatments (P<0.01). The highest growth rate of both morphology types of green and brown occur on the same weight and depth i.e., at initial weight 100g and depth 2½ m, respectively at 5.68 and 6.05% day-1. The yield of carrageenan is likely to increase in depth with the highest value at a depth of 7 m, respectively 17.12% at green type and 14.63% at brown type. The results showed that reducing growth may increase the yield of carrageenan by the increasing of water depth. Based on these results, this study can be applied to another location as long as the quality of water allows farming activities.

Brackish water vannamei shrimp aquaculture in Keburuhan village of Purworejo Regency is one of the shrimp aquaculture activities developed since 2010. Shrimp aquaculture enteprises were done by local communities which use sandy land coated by plastic sheet with an area of 1000-4500 m2. Some farmers suffered losses due to lack of technical knowledge in shrimp aquaculture, environmental carrying capacity, ecological and economic feasibility. The aim of this study was to determine the general condition of vannamei shrimp aquaculture and shrimp farming feasibility. The study was conducted by field surveys, interviews and questionnaires to 30 farmers. The survey was conducted in May-June 2016 by purposive sampling of farmers who were members of a joint venture group of Minamulyo. The results showed shrimp pond size aquaculture area was varied, with a range of 1000-1500 m2, 1500-2000 m2, 2000-3000 m2 and 3000-4500 m2. An average fixed cost required for construction and operation of shrimp pond aquaculture was approximately IDR 6,620,934 to 12,606,666 million/plot/cycle shrimp production, while the variable costs of each cycle production ranged from IDR 45,876,733 to 78,861,666. The revenue and net profit varied according to pond size. The net gain for the smallest pond (1000-1500 m2) was IDR 48,702,332/plot/cycle, and the largest pond (3000-4500 m2) was IDR 58,131,666/plot/cycle. The shrimp farmers could recover the original investment incurred within a period of 4-6 months (one half cycles). Vannamei shrimp aquaculture in Keburuhan village of Purworejo regency brings a variety positive and negative impacts to the development of the economic, social and environment. Positive impact included increase of income and welfare of farmers, while the negative impact was a decline in the quality of the pond environment.

The shrimp infected by Taura syndrome virus (TSV) can survive until harvesting time. At this phase, the growth of this shrimp is relatively normal but it is referred as TSV carrier. This research is expected to provide a recommendation in effort to prevent the occurrence of TSV infection. Therefore, this study was aimed to evaluate the DNA polymorhism of Pacific white shrimp L. vannamei infected by TSV. A total of 60 samples of L. vannamei were collected from SPF (specific pathogen free)-Florida, F1-healthy, F1-tolerance (it is can life normally after infected by TSV), and F1-moribund (diying after infected by TSV). The samples were analysis using PCR with IQ-2000 KIT to determine the positive infection of samples. DNA profile of white shrimp, L. vannamei was significantly different from SPF Florida, F1-moribund, and F1-healthy shrimp. This expression may control the defense mechanism. This can be ascribed to the reason that shrimp survived from TSV infection had a higher amount of locus (3 loci) that were detected from DNA polymorphism of gene in white shrimp contributed to a gene control that was determined from allele variation. Two important alleles (200 bp and 220 bp) unique may be associated with tolerant trait. Those loci only found in F1-tolerance shrimp. However to prove that further necessary to sequences a nucleotide of three loci as responsible for resistance to TSV infection.

The Impact of Component Modification of “Double Bottom Filter” Recirculation System to Concentration of Ammonia in Water and Survival Rate at Rearing Media of Blue Devil Fish (Chrysiptera cyanea) F. Sahetapy, Jacqueline M; Louhenapessy, Daniel G; Riry, Elna C

Blue devil (Chrysiptera cyanea), blue damselfish, is a variety of marine ornamental fish. In rearing ornamental fish, water quality management is required to maintain the optimal condition of water quality. Filtration and recirculation are proven as preeminent ways to manage the optimal condition of water quality in aquarium as the vessel for rearing ornamental fish. Simple recirculation system double bottom filter was applied in this research with treatments of components modification of the system. The objective of the research was to identify the concentration of ammonia in rearing media of blue devil (C. cyanea) using recirculation system double bottom filter with several modification components. The treatments are i.e. (1) no recirculation/aeration only (treatment A), (2) system with components of sand and dacron (treatment B), (3) sand and sponge (treatment C). The result showed that the ammonia concentration in system A (control) was 0.890 mg/L, system B (sand and dacron) was 0.129 mg/L, and system C (sand and sponge) was 0.7 mg/L. The highest value of survival rate was in system B (components sand and dacron) which valued 90%. As the conclusion, component sand and dacron in recirculation system double bottom filter provided better performance in reducing ammonia in rearing media of blue devil (C. cyanea) which also confirmed with the survival rate value.

As sea cucumber, Holothuria scabra is one of the fishery commodities which have high economic value, this species now is under overexploited. Sea cucumber aquaculture should be developed urgently. This research was conducted to evaluate the effects of stocking densities on the growth and survival rates of sea cucumber. This research was carried out by using pen culture with 5 – 9 cm in length or 30 – 50 g of seedlings. The sea cucumber was reared with stocking densities of 15 (treatment A), 20 (treatment B) and 25 individual/m2 (treatment C) in triplicates. The observation of growth and survival rates were done every two week. The water quality was measured every three day. The result indicated that the growth and survival rates was higher in treatment A than treatments B and C.

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
