Study on bioconversion of ω-fatty acids extracted from giant snakehead (Channa micropeltes) fish oil was carried out using guinea pig lung homogenate. The fish oil, after hydrolysis to their fatty acids, was incubated aerobically at 37oC in phosphate buffer solution with the addition of guinea pig lung homogenate. After incubation and chemoreduction, it was found that ca. 76% arachidonic acid h...

Ex-coal mining void has changed landscape shape, physical-chemical, and soil biological properties. As a form of post-mining management, the company must restore damaged land increase its benefits for surrounding community, one which is as freshwater aquaculture area. This study was conducted in 50.26 ha concession area coal PT. Mitrabara Adiperdana (MAP) Malinau Regency, North Kalimantan. The ...

This study aimed to test the hypothesis that the aerial survival of the northern snakehead is involved not only with suprabranchial chamber respiration but also with physiological regulations. The aerial survival time and oxygen consumption rate (VO2) were determined in snakeheads with either normal or injured suprabranchial organs. Some hematological and biochemical parameters were assessed du...

Snakehead fish as a of high economic value is currently still caught through nature where cork maintenance has not been widely done. contains protein, good for health can also recover damaged. This investigation intends to produce findings from earlier research into the feeding patterns snakehead (Channa striata) in aquatic environments. Because it serve resource public and other parties terms ...

The increasing intensification of aquaculture production requires the development strategies to reduce its environmental impacts such as pollution caused by discharge nutrient-rich sediments into local water bodies. This research was undertaken investigate and evaluate effect using organic fertilizers produced from pond sludge freshwater snakehead fish ( Channa striata ) composted with amendmen...

The introduction and subsequent range expansion of the Northern snakehead ( Channa argus : Channidae, Anabantiformes) is one a growing number problematic biological invasions in United States. This harmful aquatic invasive species predatory freshwater fish native to northeastern Asia that, following deliberate introduction, has established itself multiple water basins eastern States, as well ex...

The effects of feeding frequency on the specific dynamic action of the juvenile snakehead were examined. The fish were fed at four different frequencies with the same total meal intakes (4% body mass), and the postprandial oxygen consumption rate and ammonia excretion rate were determined for two days. The durations of oxygen consumption and ammonia excretion significantly increased with increa...

Snakehead fish with different geographical differences can have an impact on genetic diversity. DNA barcoding is a system designed to identify species precisely and accurately by using short standardized gene regions. This study aims determine the diversity of snakehead populations in four areas East Java. used Cytochrome b (Cyt b) sequence mitochondrial variation wild population Channa striata...

BACKGROUND Understanding different patterns of fish consumption is an important component for risk assessment of contaminants in fish. A few studies on food consumption had been conducted in Malaysia, but none of them focused specifically on fish consumption. The objectives of this study were to document the meal pattern among three major ethnics in Malaysia with respect to fish/seafood consump...
