Cyanide fishing and cyanide detection in coral reef fish using chemical tests and biosensors.
ABSTRACT Sodium cyanide has been used in the Philippines to collect tropical marine fish for aquarium and food trades since the early 1960s. Cyanide fishing is a fast method to stun and collect fish. This practice is damaging the coral reefs irreversibly. In most countries cyanide fishing is illegal, but most of the exporting and importing countries do not have test and certificate systems. Many analytical methods are available for the detection of cyanide in environmental and biological samples. However, most of the techniques are time consuming, and some lack specificity or sensitivity. Besides, an ultra sensitive cyanide detection method is needed due to the rapid detoxification mechanisms in fish. The aim of this review is to give an overview of cyanide fishing problem in the south-east Asia and current strategies to combat this destructive practice, summarise some of the methods for cyanide detection in biological samples and their disadvantages. A novel approach to detect cyanide in marine fish tissues is briefly discussed.

ABSTRACT: Illegal, unreported and unregulated (IUU) fishing is a significant problem that affects the marine ecosystem and those who depend on it for survival. Research and theory in criminology can shed light on the problem and suggest policy instruments to reduce IUU fishing. Informed by rational choice theory and situational crime prevention framework, this study examines the relationship between local situational factors and illegal fishing in 53 countries. Results suggest that a country’s risk of illegal fishing is positively related to the number of commercially significant species found within its territorial waters and its proximity to known ports of convenience. Countries that exercise effective fisheries management and have strong patrol surveillance capacity experience less illegal fishing activity within their territorial waters. The presence of legally fishing vessels does not deter illegal fishing activity. These findings demonstrate the utility of thinking about illegal fishing through the lens of criminology, which is equipped with practical tools to address the problem. Findings suggest a dialogue between criminologists and conservationists to work together to address similar problems affecting the environment.Biological Conservation 09/2014; · 4.04 Impact Factor
