Abstract

The status of fish populations is needed to properly manage these resources in order to maintain its sustainability. This study aims to examine the growth factor of some fish caught by trawl in East Kutai Regency include the length and weight relationships, condition factor, the alleged growth, Gonadal Development Level, gonadal Somatic index, and fecundity. The research was conducted in the sub-district of Kaliorang, Sangkulirang and Sandaran of East Kutai regency, East Kalimantan. Collection and measurement were conducted over a period of three months. Allometric growth patterns are found in gerot-gerot, niko-niko, teri, senangin, gulamah, bulu ayam dan lampa-lampa, while Isometric growth patterns found in puput. Highest condition factor found in gulamah with the value of 1.02 and the lowest value was found in the gerot gerot with value 0.083. The collected fish length growth equation was senangin. The Regression equation for growth length i.e. senangin Lt = 180,8 (1-e-1,7(t+1,25)), puput Lt = 221,5 (1-e-0,88(t+0,88)), and bulu ayam Lt = 200,55 (1-e-0,7(t+0,95)).

Abstract

This study aimed to determine the effect of Pseudomonas ECP and ICP injection incubated on TSA and TSB media with incubation periad of 72 hours on the nila tilapia (O. niloticus) haematology. Parameters observed were hemoglobin, hematocrit, erythrocyte total and of leukocyte total. The ECP or ICP ware injected into intraperitial nila tilapia as much as 0.2 ml/fish. Observations were made on 6, 12, 24, 48, 72, 96, 120, 144, 168 hour after injection. Extracellular products were obtained by centifuging Pseudomonas suspension grown on TSA and TSB media (incubation time 72 h + 30oC) using a 10.000 g centrifuge for 30 min at 4oC. Supernatant was filtered using filter paper 0.45 μm. To get the ICP, supernatant was centrifuged in room temperature. The results revealed that ICP injection caused the decrease of haematology faster than ECP injection. This indicates that the ICP Pseudomonas more virulent than ECP.

Abstract

Kissing gourami fish roes is a traditional salt fermented fish product widely consumed in east Kalimantan. This product is still made traditionally by applying spontaneous fermentation with added salt. This research aimed to isolate and identify bacteria found in fermented kissing gourami fish roes. The research consists of three steps: producing, isolating and bacteria-identifying. In this research kissing gourami fish roes has been fermented for one year so that fish roes fermented can be obtained. Those colonies were isolated and preserved using tryptic soy agar (TSA) media and determined using BBL Crystal method. The results described 5 (five) different colony of bacteria grew dominantly. The bacteria were identified as Bacillus megaterium, Leifsonia aquatica, Corynebacterium propinquum and Lysinibacillus sphaericus.

Abstract

This study was conducted to determine the effects of different levels of vitamin C (ascorbic acid) supplementation on NVC (Nutrition Value Coeficient), clinical signs, pathological change, phagocytic index, antibody, and survival rate of fingerlings common carp (Cyprinus carpio L.). Three diets were formulated incorporating vitamin C at levels of 0 (control), 250 and 500 mg/ kg. Fish were randomly fed with the experimental diets for 35 days. On 15th day fish were injected intra muscular with 0.1 ml/fish, 106 CFU/ml concentration of A. hydrophila. The present study suggest that vitamin C concentration 250 mg/kg of diet most appropriate concentration, can enhance fish health (NVC), immune system (phagocytic index and antibody), survival rate, normal clinical signs and pathological change after infected by A. hydrophila.

Abstract

Along with the increase in population in the Kutai National Park (Kutai NP) has raised the land issue of due to the need for living space and the exploitation of natural resources. This study is part of an effort to evaluate the condition of mangrove forests as a first step effort to protect mangrove forests as critical habitat for coastal Kutai NP. The research was conducted in March to April 2012, with the goal of evaluating and measuring vegetation cover and land use (Land use) mangrove forests in coastal Kutai NP. For this purpose, the data is used Landsat ETM + image with 7 bands that recorded in 2008. Process analysis using NDVI (Normalizet Difference Vegetation Index) composite channel by IR (bands 4 and 3), while the extent of the damage was analyzed using standard from Decree of Ministry of environment No. 201, 2004. Base on the research, Kutai National Park has the potential of ± 5192.54 ha of mangroves, mangrove forest ecological conditions in Kutai NP generally be in the grade is still good with vegetation density ranging between 967-1567 ind / ha, Kutai NP In some areas such as the Estuary Sangatta, bay and estuary Sangkima Lombok are areas that have experienced enough land conversion, overall mangrove forest that has been opened by ± 1845.85 ha or 26.2%. Mangrove forests are located close to residential vulnerable to land-use changes.

Abstract

Zooplankton plays important role in food chain system within fresh water ecosystem. In the trophic level it acts as bridging energy from phytoplankton to fish juvenile. Meanwhile research on this plankton is considerably lacking. This study is aimed to test culturing cladocera in the laboratory. Cladocera and phytoplankton were collected from Lutan Lake-Palangkaraya and the transported to the laboratory. Three fish water tank were used to culture cladocera for 5-week testing. The results indicate that there was a negative relationship between average numbers of cladocera dan phytoplankton during culturing period. Two-week culturing period was identified as the most optimal period for culturing cladocera under laboratory condition.
