Parasite infections in aquaculture can trigger primary infections due to decreased fish immunity making it easier for other microorganisms, both bacteria and viruses, to enter the fish's body. This study aims to identify, calculate the prevalence and intensity of parasites that found in catfish ponds of the "Mino Ngremboko" fish farmers group in Grabag Village, Grabag District, Purworejo Regency. This study used the scraping method by reviewing the gills, mucus from the skin, fins and digestive tract onto a glass object which was then observed microscopically using a light microscope with a magnification of 10-40x. The parasites found were ectoparasites consisting of 6 species; Trichodina sp., Tetrahymena sp., Gyrodactylus sp., Epistylis sp., and Dactylogyrus sp. No parasites were found from the endoparasite and hematozoa groups. The highest prevalence was Dactylogyrus sp. with a prevalence rate of 54% and the lowest was Dinoflagella with a prevalence rate of 10%. The highest and lowest parasite intensities were Epistylis sp. (18,0 ind./infected fish) and Dactylogyrus sp. (2,8 ind./infected fish), respectively. It can be concluded that the level of parasitic infections in the fish farmer groups ponds was at the "common-usually” level based on William and Bunkley's prevalence criteria.Key words: Clarias sp., identification of Parasite, prevalence, intensity, Mino Ngremboko

Guppy fish is currently in high demand because they has interesting color variations such as red, blue, yellow. The carotenoid content in red peppers and red spinach is able to increase the brightness of the color of the fish. This research aims to find out the effect of the addition of red peppers and red spinach on guppy fish color. Completely Randomized Design with 3 treatment and 3 repetitions was used. The research data was analyzed by using the Adope Photoshop app by observing the discoloration that occurred before and after the treatment by using color libraries. The study found that the percentage of blue and purple in guppy fish increased. This was related to the absence of carotene that associated with protein and produces carotenoproteins. The most prominent discoloration result was the treatment 1 (addition of peppers). In treatment 1 there was a significant discoloration of the blue color with the code 732-0 from 0% to 11.9%, while in the treatment 2 (addition of spinach) color coded 732-0 was changed from 0% to 5.88%, the treatment 3(control) treatment was changed from 1.21 % to 0.6%. Meanwhile, the purple color with the code 728-0 on treatment 1 from 0% to 2.36%, on treatment 2 from 0% to 0.22% and on treatment 3 purple color did not came out. It can be concluded that the most influential to the color of guppy fish was peppers, spinach and control treatment, respectively.Keywords : red spinach, carotene, guppy fish, red peppers, color.
