Abstract:
Fish like many living organisms have specific tolerant range of various environmental parameters, thus fish larvae ponds of specific types of fish species requires certain conditions that have to be reach. People that work in the fish larvae ponds have to be engaged in all day activities to maintain the living fish larvae habitat. One important parameter for fish larvae ponds is temperature. Larvae that have hatched should be raise in a special place. Stocking density for maintenance of 50-100 larvae/m2. To avoid the cold weather occurs, warming can be do with halogen lamps. Solar Energy is produced by the Sunlight is a non-vanishing renewable source of energy which is free from ecofriendly. The highest intensity of sunlight occurs at 11.00-14.00 with the value of the intensity of sunlight is 90100-112500 lumens. Based on condition and calculation, the fish larvae pond need 4 solar panels, 2 batteries, and 4 halogen lamps. Monitoring and taking actions to maintain the habitat’s susta
inable environment to certain larvae inside of ponds. Halogen lamps give the warmth to the water with the intensity of the light in cash about 1.2o C increase every minutes. It is using a thermostat to keep the water temperature as needed by the fish larvae about 27o C until 30 o C all night.
