Abstract

Many countries of Asia, including Indonesia, have experienced the problem of hypoxic fish kills among fish in netpens and fish corrals in various publicly-held water bodies. Fish farming in enclosures in public water bodies attractive because of low overhead costs in comparison to farming the identical species in constructed ponds. But aerobic bacterial degradation of feed and fish feces in common waters can lead to oxygen depletion, thus causing fish kills. Mass-balance and ecological carrying capacity models and education through and extension programming can be used to inform policy makers as to the maximum biomass of farmed fish allowable before risking hypoxia. Economic modeling of social costs and lost revenue in fish kills can also be used to inform and refine public policies. Tools for managing aquaculture carrying capacity might include managing demand for permits by increasing fees, holding auctions for fixed numbers of permits, or using a system of capping, developing offset charges for finfish effluents, and trading of rights to discharge. In this system, holders of finfish netpen permits would pay an offset to nearby aquafarmers conducting nutrient extractive forms of aquaculture (e.g. bivalve or seaweed farming), thus making often desired Integrated Multitrophic Aquaculture (IMTA) systems more economically viable. The important work of translating recommendations from environmental and economic modeling into practical public policy and management practice requires a considerable effort in extension programming and ongoing exchange among the scientific, industry, regulatory and policy-making communities.

Abstract

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.

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

One of the solutions to maximize diet usage when the feeding is not in line with the growth of Catfish (Pangasius hypothalamus) is by introduction of fish new culture system.  The new culture system is by incorporating Saccharomyces cerevisiae into the feed.  It aims to increase feed efficiency; in turn it increases the growth.  The objective of the research is to study the effects of S.cereviceae incorporated diet on growth performance, apparent digestibility coefficient of protein and survival rate of catfish (P. hypothalamus).  The fish used in the study were 4.02±0.22 g per fish. The study used experimental method with completely random Design.  The experiments were in 4 (four) treatments.  Each treatment had 4 (four) repetitions.  The treatments were by feeding fish with 4 (four) different dosages of S. cerevisiae addition in the diet.  The dosages were 0 g per kg feed (A), 0.5 g per kg feed (B), 1 g per kg feed (C) and 2 g per kg feed (D).  The results show that the incorporated S. cerevisiae feed was significant (P<0.05) on the specific growth rate (SGR), apparent digestibility coefficient of protein (ADCP) and survival rate (SR) of the catfish (P. hypothalamus) fingerlings.  The best dosage was 1.0 g of S. cerevisiae per kg feed and the optimum dosage ranged from 1 to 1.12 g/kg feed for SGR, ADCP and SR of the Catfish (P. hypothalamus) fingerlings.

Abstract

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).

Abstract

Water pollution effect on aquatic organisms and if consumed can affect people's health. These pollutants can be heavy metals such as Cd, Pb, Cr, Hg, and others. Heavy metals have high levels will cause disorders of the kidneys, brain, severe irritation to the skin, can cause diarrhea and even death. The purpose of this paper is to explain physiological mechanisms that occur in the body of gastropods are linked to pollutants in the water environment. Therefore, monitoring the level of pollution a body of water that is alleged to have suffered contamination is very important. Gastropods are one of the aquatic animals (Class) used as bioindicators and biomonitoring for this group of animals has a high ability to accumulate heavy metals in their bodies compared to other aquatic animals. Gastropods is one bioavailability against metal pollution so that it can be used for environmental monitoring. Littoraria scabra, Nassarius reticulatus, Nerita albicilla, Nucella lapillus, Gibberulus gibbosus, Terebralia palustris, and Telescopium telescopiun always use as biomonitoring metal pollution. The main indicator that can be shown by gastropods is declining abundance and body size. Other indicators are as bioavailability of heavy metals in the soft tissues and shells. The ability of the heavy metal deposits is influenced by environmental factors, body size, weight, and gender. Heavy metals can affect hard, thickness, volume, and color of the shell.

Abstract

We investigated the effects of feeding rate on the growth, blood components, and histology of the growing olive flounder (Paralichthys olivaceus). We determined the optimum feeding rate (initial fish mean weight = 525.3 ± 7.12 g) at the optimum water temperature. Two replicate groups of fish were fed a commercial diet at rates of 0%, 0.2%, 0.4%, 0.6%, and 0.8% (i.e., to satiation) of body weight (BW) per day. The feeding trial was conducted using a flow-through system, with ten of 1.2-metric-ton aquaria receiving filtered seawater between 20.5 and 24.5°C, for 3 weeks. Weight gain (WG) and specific growth rate (SGR) were significantly greater in fish fed with satiation at 0.8% BW/day compared to fish fed at 0.2% BW/day, and with unfed fish. These parameters were negative, and significantly lower, in the starved fish compared to the fish fed the experimental diet, for all feeding rates. There were no significant differences in WG and SGR among fish fed at 0.2%, 0.4%, and 0.6% BW/day, and among those fed at 0.4%, 0.6% and 0.8% of BW/day. The histological changes in tissues were not significant in the hepatopancreas, kidney, or anterior intestine of fish fed at 0%, 0.4%, and 0.8% of BW/day. Broken-line regression analysis based on weight gain demonstrated that the optimum feeding rate for an olive flounder weighing 525 g was 0.70% BW/day at optimum water temperature.

Abstract

A multiple genes family claudin encodes proteins which forms main structures of tight junction between epithelial cells. In intestinal epithelium claudin proteins are proposed to have roles in ion balances regulation and forming barrier against pathogenic invasion. In the present work, claudin genes were molecularly identified in common carp (Cyprinus carpio), one of the most important cultured fish in freshwater aquaculture. Carp claudin 1 and 2 were amplified with primers designed based on relevant known claudin genes in fish. On the basis of carp ESTs, other six carp claudin genes were amplified. The amplification products were cloned and sequenced. Phylogenetic and sequence analysis confirmed that the eight identified genes are claudin genes and could be designated as carp claudin 1, 2, 3b, 3c, 7, 11, 23, and 30, respectively. This finding could be used to develop further study of carp claudin especially roles of claudin during pathogen infection and strategy to modulate its expression in order to protect diseases in carp aquaculture.
