Calculation of vibrio and plankton is very necessary in vannamei shrimp farming activities, it affects in productivity. Therefore, it is necessary to calculate the density of vibrio and abundance of plankton to support the productivity of vannamei shrimp farming. The purpose of this study was to find out how to check vibrio density and plankton abundance on the productivity of vannamei shrimp culture. TBC and TVC calculations were carried out in ponds A4 and A6 using a hand counter once every 10 days. Calculation of plankton abundance using a haemocytometer is done every 5 days. The abundance of plankton in the waters is very beneficial, to suppress the development of Vibrio sp. Pond C4 in DOC 20 with an abundance of 9.0x10³ cells/ml plankton was able to suppress TVC 2.9x10³ CFU/ml. Whereas, pond C6 in DOC 20 with an abundance of plankton 6.8x10³ cells/ml was able to suppress TVC 3.8x10³ CFU/ml. The abundance of vibrio affects the productivity of shrimp, wherease the higher TVC affects the decrease in Average Daily Growth. TVC in Pond C4 at DOC 90 with an abundance 2.2x10³ CFU/ml affected decreament of ADG by 0.45 gr. Likewise, the lower the TVC affects increament of ADG. TVC in Pond C6 with abundance 2.4x10³ CFU/ml affected increament of ADG by 0.57 gr.","PeriodicalId":476491,"journal":{"name":"Jurnal Perikanan Pantura","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135032190","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A challenge in green mussel cultivation is the presence of diseases caused by parasites that attach or live on the mussels. This research aims to determine the abundance of ectoparasites and competitors on green mussels in the mentioned waters. The research methods employed both qualitative and quantitative descriptive approaches. The observed research variables included species identification, prevalence and intensity of ectoparasites, as well as diversity and abundance of competitors. The findings revealed the presence of 2 ectoparasite species and 10 competitor species. The highest prevalence of Balanus sp. was recorded in Bagan Tancap I for mussels larger than 4 cm, at 79.6%±6.16 (moderate), while the lowest prevalence was in Bagan Tancap II for mussels smaller than 4 cm, at 33.3%±1.05 (common). The highest intensity of Balanus sp. ectoparasite attacks occurred in Bagan Tancap I for mussels larger than 4 cm, at 7.18 ind/mussel (moderate), and the lowest intensity was in Bagan Tancap II for mussels smaller than 4 cm, at 1.75 ind/mussel (low). The intensity of sea snail egg infestations ranged from 1 to 2 ind/mussel, with no significant difference (P>0.05). The highest competitor abundance was found in Bagan Tancap I with the species Nereis sp., at 0.57 ind/mussel, and the highest competitor diversity was also observed in Bagan Tancap I with the species crab at 36.292 ind/mussel. Considering the prevalence and intensity values of Balanus sp. ectoparasites on green mussels in the waters of the Java Sea in Kecamatan Sidayu, it is still suitable for green mussel cultivation.","PeriodicalId":476491,"journal":{"name":"Jurnal Perikanan Pantura","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135294251","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In its cultivation activities, bonylip barb are able to consume artificial feed well. The feed consumed will affect the digestive condition. The fish digestive tract is a complex system whose main functions are digestion and absorption. Nutrient absorption in intestinal cells is influenced by active transport of Na+ (sodium) ions. Na+ and Cl ion levels are obtained through water and feed. This study aims to determine the effect of salt supplementation in commercial feed with different concentrations on bacterial abundance. The research was carried out experimentally with salt supplementation doses (0%, 1%, 2%, 3%, and 4%; w/w) to be applied to bonylip barb seeds (5-7 cm) for 60 days. Research parameters include bacterial abundance, positive and negative gram tests. The results showed that the treatment with the addition of 2% NaCl gave a total number of bacteria that tended to be higher than the control (0% NaCl). The total number of bacteria in the digestive tract of Nilem fish that were given NaCl addition to the feed ranged from 3.78 ± 6.27 x 106 CFU/gram to 32.04 ± 19.51 x 106 CFU/gram. The addition of NaCl affects the proportion of gram positive and negative in the digestive tract of tilapia (Oreochromis niloticus). Gram positive bacteria tended to dominate in the 2% NaCl treatment at 69.99% and gram negative bacteria at 21.69%.","PeriodicalId":476491,"journal":{"name":"Jurnal Perikanan Pantura","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135294252","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
