Abstract

Hotate Shellfish Cultivation is the largest shellfish cultivation in the world, but many pests and parasites are found. This research aims to inventory the types of pests and parasites found in the cultivation of Hotate Shellfish (Patinopecten yessoensis) in Funka Bay, Hokkaido, Japan. The objects used for this research were 54 Hotate shellfish, consisting of three life stages of shellfish, namely seed shellfish, juvenile shellfish, and adult shellfish. This research was carried out using observation and random sampling methods to determine the types and percentages of pests and parasites present during the research. This research was carried out for seven months from 13 April to 6 December 2022 at the Daisan Matsui Company, Ohama, Oshamambe, Hokkaido, Japan. The results of this research show that there are four types of pests, namely Starfish, Purple Shellfish, Crustaceans, and Sea Pineapples as well as two types of parasites, namely Annelid Worms and Barnacles which attack shellfish cultivation. The percentage of shellfish at three life stages that were attacked by parasites was 75.93%. There are several factors that control the attachment of pests and parasites, including substrate availability, nutrient availability, and environmental considerations. The surfaces and nutrients provided by hotate culture facilities provide adequate conditions for pest settlement and growth.

Abstract

Eel (Anguilla sp.) is a leading freshwater fish commodity. In the intensivesystem, high stocking density results in high production costs. Maggot meal isan alternative raw material that has complete nutritional value such as fishmeal but is cheaper. The purpose of this study was to determine theeffectiveness of substituted fish meal with maggot meal on the growth andsurvival rate (Anguilla bicolor) Elver phase. The method carried out in thisstudy used an experimental method with a completely randomized design(CRD) consisting of 4 treatments and 3 replications with a combination of fishmeal and maggot meal, P0: 100% TI and 0% TM, P1: 80% TI and 20% TM,P2: TI 60% and TM 40% and P3: TI 40% and TM 60%. The results of rearingfor 60 days showed a significant effect on absolute weight growth, specificgrowth rate, and yield, while the yield had no significant effect on absolutelength growth, feed conversion, and survival. The results of the water qualityparameters of the media are temperatures ranging from 24 °C -29,8 °C, pHranging from 5,14-7,7, DO ranging from 2,4 mg/l – 5,1 mg/l and ammoniaranging from 0 ppm – 0,01 ppm.

Abstract

Algae are eukaryotic organisms with chlorophyll. Green algae contain chlorophyll, allowing them to photosynthesize directly and provide shrimp ponds with food. This study is entitled Fluctuations of Green Algae and Effects on the Growth of Pacific White Shrimp (Litopenaeus vannamei) in CV. Cemarasewu Sumber Rejeki, Cilacap. This observational study Oct–Dec 2022 monitored a pond in Cilacap. Water green algae and Pacific White Shrimp samples were taken every seven days age 64–120 days. Algae density was calculated hemocytometer, while shrimp growth parameters MBW, ADG, FCR, SR and water quality temperature, pH, DO, salinity, nutrients were measured. Data were analyzed descriptively to observe the relationship between algae fluctuations and shrimp growth. The results of the study showed that green algae experienced fluctuations during the Pacific White Shrimp cultivation period. The presence of green algae can have a good effect on the growth rate of Pacific White Shrimp. The growth rate of Pacific White Shrimp in the research pond was classified as good. The results obtained by ADG in plot B13 0.39%, B14 0.45% and B15 0.38%. MBW in plot B13 30.75 g, B14 31.68 and B15 32.05 g. FCR in plot B13 1.42, B14 1.45 and B15 1.39 and SR in plot B13 66.7%, B14 71.5% and B15 70.7%.

Abstract

Pacific White Shrimp (Litopenaeus vannamei) is a frequently cultivated shrimp species. This is because it offers promising prospects and profits. Superior vannamei can be produced by considering several aspects of the cultivation process. Internal factors include the origin and quality of the seeds, as well as external factors, including cultivation water quality, feeding, technology, and pest and disease control. This research was conducted from September 15 to October 15, 2022, at CV. Cemarasewu Sumber Rejeki, Jetis Village, Cilacap, Central Java. The purpose of this study was to determine the water quality conditions in Pacific White Shrimp rearing ponds at CV. Cemarasewu Sumber Rejeki, Cilacap. Three ponds were used for data collection: plots B13, B14, and B15, with shrimp rearing ages of 100-129 days. Research results indicated that plots B13, B14, and B15 at CV. Cemarasewu Sumber Rejeki provides good water quality for Pacific White Shrimp cultivation. The results of water quality parameters measured in this study include: brightness up to 35 cm, temperature ranging from 27-29 ºC, pH ranging from 7.6-8.3, salinity ranging from 14-22 ppt, alkalinity ranging from 125-169.6 ppm, TOM ranging from 70.4-79.2 ppm, DO ranging from 4.32-4.98 ppm, phosphate ranging from 0.25-0.5 ppm, nitrite ranging from 0.013-0.085 ppm, nitrate 0 ppm, ammonia ranging from 0.00-0.085 ppm, ammonium ranging from 0.00-0.50 ppm and plankton ranging from 2,500-282,500. It can be concluded that the water quality in pond plots B13, B14, and B15 at CV. Cemarasewu Sumber Rejeki meets the appropriate standards to support Pacific white shrimp cultivation.
