Ornamental fish trade between regions in Indonesia allows the transfer of disease, especially if the disease does not show clinical symptoms in fish traded. Koi fish in Tahuna, North Sulawesi, mostly come from the area of East Java, which is one area with many cases of myxobolusis. In addition, the potential for parasitic diseases that come along when koi fish are brought between areas cannot be avoided, because the examination of parasites, especially Myxobolus sp. no longer listed in the regulation as a quarantine inspection requirement. The purpose of this study was to see the Myxobolus sp infestation that infected koi in Tahuna, North Sulawesi, although there were no clinical symptoms using conventional techniques and histopathology. The results of the examination showed Myxobolus spore infestation on the gills of the koi, although the amount was not much, both conventional and histopathological techniques. This shows that our level of awareness of the types of parasites that can infect fish is still lacking. Myxobolus sp is only transmitted through the spore stage back and forth; there is no horizontal or vertical transmission in fish or tubifex T worm populations. More knowledge regarding the life cycle of the Myxobolus sp. in order to obtain the right handling to deal with outbreaks, especially water quality management at the location of the cultivation.

Karamunting is a plant that contains cholesterol. Cholesterol is needed by mud crabs as precursors of reproductive hormones in ovarian development. This study aims to determine the effect of karamunting leaf extract which is injected with mangrove crabs (Scylla sp) on the level of ovarian maturity. The stages of the research included extraction of karamunting leaves using ethanol 70%, experiments by injecting the parent crabs consisting of 3 treatments A (control), B treatment (0.25 mg / g body weight), C treatment (0.5 mg / g body weight) maintained for 20 days by feeding trash fish and measuring parameters including morphological ovarian development, somatic gonad index (GSI), and hepatosomatic index (HSI). The results showed that by giving karamunting extract at the end of the GSI study on control (1.70%), treatment A (5.61%), treatment B (4.24%) while on ovarian development with morphological observation at the end of the study on treatment ovarian control develops in the TKG II phase, A treatment in the TKG V phase while treatment B in TKG IV. This shows that by giving karamunting extract can provide the development of mud crab ovaries.

Fish is one of the fishery food ingredients that are needed by humans, because in the fish meat there are compounds needed by the body. Such as the content of protein compounds, fats, carbohydrates, vitamins and mineral salts. Sorong in the city of mackerel is one of the fish that are of interest to the community, and its availability is abundant at the fish auction place in the city of Sorong. But in general the consumption of mackerel has not been tested either chemically or microbiologically based on the background of the purpose of this study is to determine the total microbial plate count in fresh mackerel (Rastelliger sp.) In Sorong City, West Papua. The method in this research was descriptive method, which is drawing the number of microbes through the test of the total number of microbial plates (ALT). Based on the results of the study which stated the average of the five samples approved were in sample A and sample B the amount of ALT was 3.7 x 104 cFU/mL, sample C and sample D were 1.02 x 105 cFU/mL, and sample E as much as 2.7 x 105 cFU/mL.

FCR or feed conversion ratio is one of the strategic indicators on pond production which is very important for determining the costs incurred during the shrimp culture period. The purpose of this study was to examine the relationship between water physico-chemical parameters and the conversion rate of shrimp feed in intensive shrimp ponds (Litopenaeus vannamei). The research method used in this study is the ex-pose facto design during shrimp culture cycle with uniformity of treatment during the cultivation process, then the research collective data obtained periodically is analyzed by multiple linear regression. The results of this study indicate that all pond water quality variables based on quality standards are still in accordance with the standards intended for aquaculture. While based on regression analysis and t-test, the temperature variable is the only parameter that has a direct influence on the FCR efficiency by shrimp. As well as temperature, salinity, and alkalinity variables are parameters that have a close level of relationship to the FCR value in the ponds of 84.1%, 79.1%, and 69.9%. The conclusion of this study is that in intensive ponds the parameters of temperature, salinity, and alkalinity are water quality parameters that have a close relationship with the efficiency of FCR values in ponds, with temperature parameters being the water quality variable which has a direct influence on the effectiveness of the feed conversion ratio by shrimp.
