One among the technologies, which has greater developments, is the solar powered automatic shrimp feeding system. For instance, the solar power which is a renewable energy can be an alternative solution to energy crisis and basically reducing man power by using it in an automatic manner. The researchers believe an automatic shrimp feeding system may help solve problems on manual feeding operations. The project study aimed to design and develop a solar powered automatic shrimp feeding system. It specifically sought to prepare the design specifications of the project, to determine the methods of fabrication and assembly, and to test the response time of the automatic shrimp feeding system. The researchers designed and developed an automatic system which utilizes a 10 hour timer to be set in intervals preferred by the user and will undergo a continuous process. The magnetic contactor acts as a switch connected to the 10 hour timer which controls the activation or termination of electrical loads and powered by means of a solar panel outputting electrical power, and a rechargeable battery in electrical communication with the solar panel for storing the power. By undergoing through series of testing, the components of the modified system were proven functional and were operating within the desired output. It was recommended that the timer to be used should be tested to avoid malfunction and achieve the fully automatic system and that the system may be improved to handle changes in scope of the project.

Shrimp yield in ponds can be increased by applying modern farming techniques such as intensification of culture operation through regularization of pond size, increased stock density, employment of aeration, and application of formulated feed. This will mean a considerable increase in financial and high technology inputs which most small farmers in the developing countries may not be able to afford. It is a must for a pond farm business owner to consider shrimps’ health: that they are fed regularly in controlled portions in order to maximize growth and vitality, without the risks of overfeeding. Shrimp farming is a business. Like any business, businessmen should assure the continuous increasing production of the harvests. Such necessities are so called automatic feeders for regulated time varying feeding system that influences the growth of the shrimps. In most farms, feeding of shrimp is done by hand. This practice of manual feeding is very time consuming, especially for ponds of large areas. Problems arise from shrimps getting diseases from uncontrolled amount of feeds, resulting to unhealthy harvests. The project is a feeder for the Vanname shrimps. The system is automatic in terms of dispensing the feeds, with regard to time. It will allow adjustable feed quantity and time helpful in maintaining the shrimp's health because of small portion feeding at scheduled intervals and precise feeding at appropriate times. This will also prevent overeating by releasing the right quantity of food, at scheduled times and assures well fed, healthy shrimps. The research study performed evaluation of the existing MCU based solar powered chicken feeder and showed that there is a need to develop a different
