Abstract

<p>Pressure lamp that uses kerosene as fuel has been used for the fishing lights for more than a half century at the Lake Tanganyika. Fuel cost increasing due to high oil prices have put pressure on the management of the dagaa fishing vessels.</p><p>On February 2013, LED light has been introduced to a few dagaa fishing vessels as the fishing lights for the first time in Kigoma town, Tanzania. This paper reports the changes of cash flow of the fishing vessels operation by newly introduced LED fishing light. Fisheries have increased and operating costs of the vessels have decreased with the LED fishing lights. The cost related to the fishing light decreased remarkably. It is suggested that this LED fishing light might bring a preferable effect to raise the fishermen’s cash income. On the contrary it might lead resource depletion. Some new regulations are required to prevent the resource depletion.</p>
