Development of dissolved oxygen monitoring system for fish ponds

Dissolved oxygen is probably the single most important water quality factor that pond managers need to understand. The purpose of the present study is to create a program that helps fish pond owners and aqua culturist in producing high quality fishes by maintaining normal level of dissolved oxygen in fish ponds. Also through this system, it will solve the long time problem of fish-kill in fishponds. The study was tested in ponds and rivers in Kawit and Noveleta, Cavite. The researchers joined the Bureau of Fisheries and Aquatic Resources during the actual rounds of monitoring water quality in the said area. Of the 20 respondents, all gave excellent rating for the criteria included in the survey, the speed, user friendliness, reliability, and security. The user friendliness got the highest score, followed by reliability, security, and speed which got the lowest score. Based on the findings of this paper, the program´s speed, reliability, user friendliness, and security are all ranked excellent by the respondents.
