Abstract

One of the fundamental problems in tilapia aquaculture is the decline in water quality in the hatchery. The seed stage is more vulnerable to environmental changes that can reduce the gowth process of seeds and will further cause death. This study aims to determine the effect of fortification of papaya leaf flour (Carica papaya L.) to stimulate tilapia gowth. This study used an experimental method to treat different doses of papaya leaf flour mixed into the feed, namely 0%, 2%, 4%, and 6%, with the test animals used as tilapia seeds measuring 1.4 gams with a length of 3.2 cm. The proximate test results showed that the moisture, ash, crude fat, crude protein, crude fiber, and BETN content were suitable for tilapia fish needs. After 30 days of rearing with the test feed, there was an effect on the specific gowth rate parameters on day 15 and day 30 and the average absolute gowth. The best specific gowth rate (SG) at a dose of 2% was obtained at 6.606% on day 15 and 4.400% on day 30. The best average absolute gowth was obtained at 2% dose feeding with tilapia weight of 6.606 gams and length of 4.400 cm.

Abstract

Tilapia is a widely favored type of fish because it has thick meat and a delicious taste. The use of probiotics in tilapia maintenance can increase immunity from disease attacks through the addition of probiotics can increase the nutritional content of feed protein and maintain the balance of digestive tract microbes. The study aims to provide feed enriched with Bacillus subtilis probiotics to see parameters in the form of immune responses through blood pictures in tilapia, survival rates, and daily growth rate values. Tilapia seeds (5-7cm) were maintained in maintenance tanks with 5 treatments and 3 repetitions in the form of treatment without additional B. subtilis, addition of B. subtilis 10³ CFU / mL, addition of B. subtilis 105 CFU / mL, addition of B. subtilis 107 CFU / mL, and treatment with the addition of B. subtilis 109 CFU / mL. The results obtained showed that the addition of B. subtilis probiotics to saline tilapia fish feed with a concentration of 107 CFU/mL could increase the number of erythrocytes and was able to increase the survival value, as well as the daily growth rate of saline tilapia fish (O. niloticus) significantly. However, they did not affect the number of fish leukocytes during maintenance.

Abstract

One of the areas directly adjacent to the Makassar Strait is the city of Mamuju, which is a potential area for tuna (Euthynnus affinis) fishing. This study aimed to analyze the spatial and temporal mapping of tuna ZPPI based on remote sensing GIS technology for fisheries in the Makassar Strait waters, West Sulawesi. The research method used in-situ data: fishing position, catch results, and oceanographic dynamics. Ex-situ data used monthly image data of sea surface temperature (SST), chlorophyll-a (aqua modis). The data was processed using multiple regression analysis between catch results and several oceanographic parameters. The results were then visualized as a map with a Geographic Information System (GIS) using ArcView 10.2 software to obtain potential tuna fishing areas in the Makassar Strait. The results showed a strong correlation between SST and chlorophyll-a with catch results, which was 83.5%. In addition, temporal time data for fishing was obtained in March, April, May, and June. The coordinates of the fishing area points for March are 118o50'12” and 2O 45'5”; in April, they are at 118O 23'15” and 2O30'4”; in May, they are at 118o 23'0” and 2 o30’4”; and in June they are at 118 o23’0” and 2 o28’0”. The Fishing Potential Zone (ZPPI) for tuna is at 118 o27’ and 2 o29’ 32” to 118 o16’ 48” and 2 o16’ 48”.

Abstract

Freshwater lobster (Cherax quadricarinatus) is a fishery commodity with high economic value, and market demand continues to increase. However, one of the main challenges in cultivating freshwater lobsters is the low survival rate of fry, especially in the early stages of development. This research aims to optimize the dosage of a combination of amino acids and dissolved glucose to meet the nutritional needs of freshwater lobster fry and support their survival. This research was carried out at the Agriculture, Livestock, and Fisheries Greenhouse, Muhammadiyah University of Parepare, using freshwater lobster fry from captive breeding. The research method used was a Completely Randomized Design (CRD) with four treatment doses of a combination of amino acids and dissolved glucose, namely: A) 100 ppm glucose + 250 ppm amino acids, B) 150 ppm glucose + 200 ppm amino acids, C) 200 ppm glucose + 150 ppm amino acids, and D) 250 ppm glucose + 100 ppm amino acids, each with three replications. The parameters explained are the chemical composition of the body, including protein, fat, fiber, and BETN content. A combination dose of 250 ppm glucose and 100 ppm amino acids is most effective in improving the nutritional quality of freshwater lobsters (Cherax quadricarinatus). The results of this study show the highest protein content (14.28%), fat content (0.89%), and fiber content (0.7%), all of which are important for the growth and health of lobsters. Meanwhile, the combined dose of 100 ppm glucose + 250 ppm amino acids yielded the best BETN (4.95%). Overall, the 250-ppm glucose and 100 ppm amino acid combination is optimal for improving the chemical composition of the lobster's body.
