Abstract

Aneuk Laot Lake is located in Sabang City, Weh Island, Aceh Province. Changes in water quality can affect the life of aquatic organisms found in Aneuk Laot Lake. The purpose of this research estimates fish production and trophic status for the aquatic resource management of Aneuk Laot Lake, Sabang. This research was conducted in September 2019 in Lake Aneuk Laot using the TRIX, TSI (Trophic State Index) and Nygaard index methods to determine fish production and trophic status. Observation stations were determined using stratified random sampling method and analysis of chlorophyll-a was done using the Trichomatic method. The results showed that the waters of Aneuk Laot Lake can be categorized as eutrophic to hypereutrophic. The estimated value of fish production in Aneuk Laot Lake based on the chlorophyll-a approach is 109.84 kg/ha/year, with a lake area of 61.6 ha. Water quality parameters are still in a state that can be tolerated by aquatic organisms in Aneuk Laot Lake.Keywords:Fish production potential Water qualityTRIX indexBiomass productionWater productivity

Abstract

Changing in photoperiod duration may affects the physiology of nocturnal fish such as Pangasianodon hypophthalmus. A study aims to understand the effects of controlled photoperiod towards survival and growth of P. hypophthalmus has been conducted from June to August 2020. There were 3 treatments applied, namely natural photoperiod, 18 hours dark (18D), and 24 hours dark (24D) with 3 replications in each treatment. The rearing tanks used in this study were 100 L circular plastic tanks.  In 24D treatment, the tanks were placed under dark colored tarp tent continuously.  For the 18D treatment, the tanks were placed under dark tarp tent, but the tent was opened for 6 hours/ day (the tanks were in dark condition for 18 hours/ day), while the control tanks were positioned under natural photoperiod. P. hypophthalmus fingerlings, 6-8 cm TL and   4-5 g BW were used in this study. Thirty fishes were reared in each rearing tank, they were feed with commercial pellets, 2 times/day, at satiation. Fish survival was monitored every day, while samplings for fish growth were conducted weekly for a 8 weeks period. Results indicate that the survival of   fish was 100% in each treatment applied. Fish growth, however, shown differences. The growth of fish reared in 24D and 18D was better than that of the control. By the 9th week,  the fish in 24D was around 70.71g BW with 19.27 cm TL  (daily growth rate 9.35%), while those of the 18D was 69.41 g BW, 18.77 cm TL and 9.29% daily growth rate. The fish reared under natural photoperiod was around 61.95 g BW with 18.19 cm TL and 7.33% of daily growth rate. Data obtained indicate that the application of longer dark is positively improve the growth of P. hypophthalmus.Keywords:Nocturnal FishLight Dark Catfish

Abstract

Abstract. The objective of present study was to evaluate the possibility of  papaya’s latex (Carica papaya) as anti stress or larvaside for tiger shrimp (Panaeus monodon) post larvae Pl 14-30 during transportation. The tiger shrimp post larvae was collected from BBAP Ujung Batee, Aceh Besar on September, 2012. Reseach method used the completely random design with two factors, density of post larvae with three treatments (1000; 1500 dan 2000 ind/l) and concentration of papaya’s latex with four treatments (0; 100; 200 dan 300 ppm) and three replications for each treatments. The effect of papaya’s latex on tiger shrimp post larvae was observed by calculating the percentage of post larvae’s survival rate. The calculation was only done after twelve hours of transportation, due to the everage of survival rate percentage of post larvae on all levels of density was less than 50%.  The ANOVA test showed that  the density and the concentration factors gave significance effect on survival rate of tiger shrimp post larvae (P0,05). The results showed that survival rate of tiger shrimp post larvae (PL 14-30) were decreased with increasing of larvae density and concentration of papaya’s latex.  However, Duncan’s test showed that the highest survival rate was obtained at 1.000 ind/l  and 0 ppm of papaya’s latex. Hence, the effect of papaya’s latex concentration treatments in this study was larvaside on tiger shrimp post larvae.Key words: Closed transportation system, dissolved oxygen, enzyme papain, tiger shrimp post larvae.

Abstract

Shark is a cartilaginous fish that is widely hunted because it has high economic value. The waters of Aceh are directly adjacent to the Indian Ocean and the Malacca Strait making it a preferred habitat for pelagic fish, especially sharks. Information on shark species landed in the waters west and east of Aceh is very limited due to difficulties in identification and commonly used local names. This study aimed to determine the types of sharks landed in Banda Aceh, Meulaboh, Langsa, Southwest Aceh and Simeulu and to find out specifically what species of sharks are most often landed in Aceh waters. Primary data gathering consisted of four stages, namely sample collection, identification using identification books, molecular identification cytochrome oxidase subunit I (COI) and phylogenetic analysis. The results of the molecular analysis of 46 tissue samples from five locations identified 13 species of sharks, namely Carcharhinhus sorrah, Carcharhinhus amboinensis, Triaenodon obesus, Isurus oxyrinchus, Sphyrna zygaena, Sphyrna lewini, Loxodon macrorhinus, Hemipristis elongaria, Stagostoma fasciatum, Nebrius ferrugineus, Chilloscyllium punctatum, Isurus oxyrinchus, Alopias pelagicus, Alopias supercillosus and 1 species of rays, namely Rhynchobatus australiae. Phylogenetic tree reconstruction using the Neighbor Joining method of 610 basepairs consisting of two large clades separates the species Alopias pelagicus and Isurus oxyrichus with Carcharhinus sorrah, Sphyrna lewini, Loxodon macrorhinus and Rhyncobatus australiae with boostrap values of 87% and 64%. The haplotype diversity shown ranged from 0.667-0.889 while the nucleotide diversity ranged from 0.001-0.097. These values indicates high diversity because of the variance in the number of species found.Keywords:BarcodeCOISharks catchAlopias supercillosusSphyrna lewini

Abstract

Chitosan is an ingredient that can be used as a feed additive. In aquaculture, chitosan can be used as an antimicrobial, antifungal, antioxidant growth-promoting and immunostimulant. This study aims to determine the optimum addition of chitosan to feed to increase growth and daily feed consumption of giant gourami. The method used in this research is an experimental method using a completely randomized design (CRD), which consists of five treatments and three replications. The treatments used were (A) without chitosan (control), (B) 2.5 g/kg feed, (C) 5 g/kg feed, (D) 7.5 g/kg feed, and (E) giving chitosan of 10 g/kg feed. The test fish used were giant gourami with a 6 – 8 cm length and a weight of 8 – 10 g. The container used was hapa measuring 1 x 1 x 1 m3 with a density of 15 fish per treatment and 42 days of maintenance. The feeding rate was 3% of the fish biomass. Data from observations of length and weight were analyzed using Analysis of Variance (ANOVA) with a 95% confidence level; if there was a significant difference, Duncan's multiple distance test was performed. The results showed that addition of chitosan 7.5 g/kg feed was effective in improving growth on giant gourami. During maintenance, absolute length growth was 2.90 ± 0.10 cm, absolute weight growth was 15.33 ± 1.19 g, daily growth was 36.51 ± 2.84%, feed conversion ratio was 1.69 ± 0.06, and survival rate was 100 ± 0.00%. This research concluded that the optimum level of addition of chitosan to increase growth and daily feed consumption of giant gourami was 7.5 g/kg feed.Keywords:ChitosanFeed additiveGiant gouramiGrowth

Abstract

Blue swimming crab (Portunus pelagicus) is the dominant catch in Betahwalang, Demak, and the most important export fish commodity, particularly to USA. The high demand for this crab has been promoting an excessive fishing effort, causing a decrease in the crab's natural stock. This study aims to investigate the biological condition of P. pelagicus on the northern coast of Central Java and assess the crab stock exploitation status in this study area. Carapace width, body weight, Gonad Maturity Stages (GMS), and sex of crab samples were collected from the fishers and collectors landing sites or meeting points. This study employs a simple random sampling technique with no replacement. This study revealed that the maximum carapace width of female crabs was 56-164 mm, and the estimated carapace width at first maturity (Lm) was 98.2 mm. The relationships between carapace width and body weight between male and female crabs indicated positive and negative allometric growth patterns. During this assessment, the P. pelagicus stock indicated an 'over-exploited’ status, with an LB-SPR parameter of 19 percent and an exploitation rate (E) of 0.66. Management measures such as minimum legal size, reduced effort, and open-close areas and seasons should be implemented to achieve sustainable use of the crab fishery.Keywords:Blue swimming crabFishing gearDemak watersCarapace lengthSpawning potential ratio
