Abstract

Payangka fish (Ophieleotris aporos) is a fish that lives in freshwater and has the ability to survive in the midst of competition with other fishes that are very tough. This study aims to analyze the structure of payangka fish and the growth pattern of payangka fish in Lake Limboto. Fish samples were caught using a 2 cm net with a net length of 7 m and then a 1 m serok (sibusibu) with a total sample of 1003 fish. The results of the length structure analysis of payangka fish obtained a length range of 9.15 - 19.05cm with an average of 12.45 cm and the results of the weight structure analysis obtained a range of 9.27 - 47.97 grams with an average of 13.57 grams. The results of the analysis of the relationship between length and weight of payangka fish obtained allometric growth pattern (b = 2.92), b < 3 which means that weight gain is faster than length gain..

Abstract

Tilapia is a freshwater animal that is always in contact with the aquatic environment so that it is easily infected by bacteria through water. This study aims to identify the types of bacteria that cause diseases that attack Tilapia (Oreochromis niloticus) kept in Dimembe District, North Minahasa Regency. This study uses a descriptive exploratory research method. The results of the study found sixteen isolates and identified them as bacteria that cause Tilapia disease in North Minahasa Regency, including Aeromonas sp. (4 isolates), Plesiomonas sp. (5 isolates), and Enterobacter sp. (1 isolate). based on morphological characteristics (colonies and bacterial cells) and biochemical (catalase, oxidase and motility tests). It was found that periodic and continuous fish disease surveillance is needed to monitor the spread of fish diseases, especially Tilapia disease in North Minahasa
