Fishermen generally use light as a common way to attract fish in the fishing\nindustry. This study aimed to design a model of an underwater fishing using\nLight Emitting Diode (LED) lamp which is less costful and suitable for fishermen\nof Tanzania. Most fishermen currently use kerosene based lamps like\ncandela which consumes lots of energy leading to high cost in terms of money\nused to regenerate the energy. This running cost automatically rises up the\nprice of fish in the market. Thus with the use of LED lamp the cost will be reduced.\nThe findings from this study showed that the LED lamp consumes little\namount of energy (energy saving) compared to candela lamp which consumes\n6 liters of kerosene per 36 hours which is equivalent to three nights,\nwhile the LED lamp takes 7 batteries at once for 36 hours. The 6 liters of kerosene\ncost around 7 USD and that of 7 batteries cost is near 2 USD. The LED\nlamp can be accessed by only 15 USD the price which is nearly half the price\nof the candela lamp. The candela lamp in the market is sold around 31 USD.\nThis shows that LED lamp is more efficient in terms of conserving energy and\ncost effective than candela lamp. It is recommended that fishermen in the\nfishing industry in Tanzania should employ the usage of underwater LED\nfishing lamps as they are energy efficient. This will help the fishermen of\nTanzania to undertake the fishing activity at low cost which will result to the\ndecrease of price of fish in the market. This shows that this LED lamp has\nhigh efficiency and effectiveness to be used by fishermen compared to traditional\nmethod used by majority of them.
