Does Fishing On Drifting Fish Aggregation Devices Endanger The Survival Of Tropical Tuna?

Biologists studying tropical tuna fisheries aimed to establish if the use of drifting fish aggregation devices (FADs), a technique employed increasingly for industrial-scale tuna fishery, could act as just such an ecological trap for these species. Examination revealed that the tuna species caught from under the floating objects were less healthy than those taken from free schools. Results suggested that the tuna, in following the artificial rafts, move away from their usual migration routes, which leads them into ecologically less appropriate waters.

Does fishing on drifting fish aggregation devices endanger the survival of tropical tuna?

Fishermen hold empirical knowledge that tuna aggregate under floating objects, such as lengths of old rope, pieces of wood, or even large marine mammals. There is still no full explanation for this aggregation behaviour, but the past 20 years have seen purse-seine fishery operators take advantage of the associated concentrations of fish. Fishermen cast off floating rafts equipped with buoys which act as FADs. An enormous purse-seine net, deployed in a wide arc on either side of the vessel, encircles the school of tuna that come to shelter under the FAD. The lower part of the net is tightened, enclosing the fish in a hemisphere large enough to entrap a mass of tuna.

Electronic Handheld Blood Pressure Devices Market Reaching up to $793 Million by 2010

Electronic handheld blood pressure devices are automated blood pressure measuring devices used for measuring blood pressure at regular intervals, without causing inconvenience to the individual's daily routine. Rising healthcare expenditure and rapidly aging population are key factors contributing towards a rise in demand for such devices, particularly in the developed regions of the world. With growing environmental concerns related to the use of mercury-based traditional sphygmomanometers, developed nations have stepped up efforts to replace mercury devices with electronic blood pressure devices.

Eel Fishing Multiplies The Accidental Capture Of Other Fish By Eight

In the Ebro River delta, the fishing of elver (Anguilla anguilla) leads to the accidental capture of other fish species, with the capture of one ton of elver possibly resulting in the capture of up to 8.2 tons of accompanying species. Researchers from the Institute for Agro-Food Research and Technology (IRTA), who have assessed the effects of this method of fishing and identified the most fragile species, propose improvements in current methodologies.

Model Successfully Predicts Large River System Fish Diversity

While scientists have developed methods to predict aspects of fish diversity in specific river locations, a model to understand what factors may drive a comprehensive suite of fish biodiversity patterns in a large and complex system of rivers has been elusive. Now a group of researchers reports success using a so-called “neutral model” to study fish diversity in the sprawling Mississippi-Missouri River System.

An armored fish was about to become a mom some 380 million years ago. Though the primitive fish perished, its fossilized remains remarkably reveal an embryo and umbilical cord inside the soon-to-be mother's body.

The armored fish, shown here in this artist's rendering, may have given birth to its young tail-first, similar to some sharks and rays.
