The high price of flying fish eggs in Japan encourages South Sulawesi fishermen in Indonesia to harvest increasing quantities of eggs every year. Similarly, the increasing local demand for flying fish encourages Indonesian fishermen to use gill nets to catch more fish. As a consequence of this increasing quantity of eggs harvested and fish caught, Indonesia has become concerned about the overex...
We have developed a virtual fish tank in which computer users are represented by animated fish. The actions and interactions of the fish in the tank are meant to reflect the actions of users in the real world. Our first attempt at creating a programming environment that allowed people to customize their own fish did not work very well because users did not want to explicitly write programs to c...
A simple and rapid method was developed for the analysis of tetrodotoxin in puffer-fish tissues, and in serum and urine of humans poisoned after consuming puffer-fish, by means of high-performance liquid chromatography with tandem mass spectrometry (LC/MS/MS). Tetrodotoxin was extracted with 2% acetic acid. The extracted solution from puffer-fish tissues was diluted with water, and the extracte...
Betanodavirus is the leading cause of viral mortality in fish worldwide and a major barrier to the spread of fisheries and aquaculture. Due to the increase in aquaculture in the Persian Gulf and the occurrence of some disease symptoms in farmed and wild fish in the region, screening of Betanodavirus-sensitive fish became important. Therefore, to prevent economic losses and reduce aquatic reserv...
all analytical methods are generally based on the measurement of a parameter or parameters which are somehow related to the concentration of the species.an ideal analytical method is one in which the concentration of a species can be measured to a high degree precision and accuracy and with a high sensitivity. unfortunately finding such a method is very difficult or sometimes even impossible.in...
for several years, researchers in familiarity of efl teachers with post-method and its role in second and foreign language learners’ productions have pointed out that the opportunity to plan for a task generally develops language learners’ development (ellis, 2005). it is important to mention that the critical varies in language teaching was shown is the disappearances of the concept of method ...
The rapid development of fish farming and the increasing demand for fish have led to the dense cultivation of fish, which in turn has caused stressors for fish and thus increased the risk of disease. until now, the use of chemicals has been widely used for prevention and treatment, however, the use of chemical drugs has several negative effects on the environment (creation of resistant strains ...
Mycobacteriosis is a chronic disease of freshwater and marine fish. In the present study, Mycobacterium fortuitum from a diseased gold fish, Carassius auratus was isolated and identified by biochemical and molecular (PCR) method. The isolate was found to be resistant to rifampicin, isoniazid, pyrazinamide and ethambutol and myoconda® a nanodrug combination of rifampicin, clarithromycin and clof...
Examination of finfish populations for viral and bacterial pathogens is an important component of fish disease control programs worldwide. Two methods are commonly used for collecting tissue samples for bacteriological culture, the currently accepted standards for detection of bacterial fish pathogens. The method specified in the Office International des Epizooties Manual of Diagnostic Tests fo...
Live fish recognition in the open sea is a challenging multi-class classification task. We propose a hierarchical classification approach to recognize live fish from underwater videos. However, the hierarchical method accumulates misclassified samples into deeper layers and these accumulated errors reduce the average accuracy. We propose a set of heuristics to help construct more accurate hiera...
