Abstract

Hotate clams (Patinopecten yessoensis) are a species of Bivalvia that is often found in the waters of Funka Bay, Hokkaido, Japan. The information regarding the relationship between length and weight and condition factors for hotate clams is important for knowing their growth patterns. This research aimed to examine the length-weight relationship and conditions of 56 Hotate clams collected in August of 2022 at two different locations. The relationship between length-weight and growth patterns shows that the range of b values at stations A and B is 2.45, and 1.86 in the waters of Funka Bay while the growth pattern in Funka Bay displays negative allometric growth with r values ranging from 0.90-0.92 (strong positive correlation). The condition factor values for Hotate clams at stations A and B are 5.45 and 1.28. There is a good welfare value for Hotate clams because the condition factor (Kn) is greater than one.

Abstract

The high cost of commercial feed in Nirwana tilapia aquaculture leads to elevated production costs and reduced profits. As a solution, the provision of natural feed is proposed as an alternative to reduce production expenses. This study aims to compare the growth of Nirwana tilapia fed with three different natural feeds: Tubifex sp., Chironomus sp. larvae, and maggots. The experiment was conducted using a completely randomized design with three replicates for each treatment. The feeding rate was 3% of the fish’s body weight, administered three times a day. The parameters measured included absolute biomass, absolute length gain, daily growth rate (Specific Growth Rate, SGR), survival rate (SR), and water quality during the 30-day rearing period. The results showed that feeding Nirwana tilapia with Tubifex significantly increased growth compared to the control group (commercial pellets), Chironomus larvae, and maggots. The absolute biomass from Tubifex feeding was 5.23 ± 0.89 g, absolute length was 4.2 ± 7.8 cm, SGR was 1.52 ± 0.33%, and SR was 90%. The next highest growth was seen in Chironomus larvae, followed by maggots, with the control yielding the lowest results.

Abstract

Amylolytic bacteria in the digestive tract of tilapia are bacteria that produceamylase enzymes, which function to break down carbohydrates, thereby aidingthe digestive process. The presence of amylolytic bacteria is influenced by feedand the environment. The purpose of this study was to determine the proportionand activity index of amylolytic bacteria in the intestines of tilapia. This studyused an observational method with purposive sampling. Amylolytic bacteriawere isolated from the intestines of tilapia in Rice fish farming Blocks A and E.The successfully isolated bacteria were grown on 1% starch agar medium withan incubation time of 48 hours and observed at 24-hour intervals. Then, severalcharacteristic tests were carried out, including Gram staining, KOH, catalase,and oxidase tests. Based on the results of the study, the proportion of amylolyticbacteria was found in 10 isolates with a proportion of 44% and 12 isolates witha proportion of 48% in the intestines of tilapia from the two blocks. The averageamylolytic activity index obtained from block A was 0.96 ± 0.237, and fromblock E was 1.49 ± 0.501. The largest amylolytic activity index was obtainedin isolate KSA 19 with a value of 1.33 from block A, while from block E, thelargest amylolytic activity index value was 2.6 in isolate KSE 5.

Abstract

The type of feed commonly consumed by fish in nature can be predicted from the presence of microorganism communities in their digestive tract. One of the bacteria that plays an important role in the digestive tract is proteolytic bacteria. The purpose of this study was to determine the activity index and proportion of proteolytic bacteria from the digestive tract of udikan fish (Tor sp.) caught in the Banjaran River. The method used in this study was observation with a sampling technique conducted by purposive sampling. The activity index of proteolytic bacteria from the digestive tract of udikan fish (Tor sp.) was relatively low with an average value of 0.06 in 24-hour observations and 0.05 in 48-hour observations. The proportion of proteolytic bacteria obtained from the digestive tract of udikan fish (Tor sp.) was 33%.
