Mechanization impact of improvement of some quality indicators of wastewater in rainbow trout culture dual purpose farms in Markazi Province of Iran
Main Article Content
Abstract
The main goals of mechanization in aquaculture are to reduce production costs, improve profitability, lower production risks, maintain fish health, prevent disease outbreaks, protect environmental quality, improve farm effluent quality, and support proper nutritional management for higher productivity.
The present study was conducted to evaluate the efficiency of mechanization on wastewater quality in dual-purpose rainbow trout culture farms in Markazi Province, Iran. A total of 30 dual-purpose rainbow trout farms with high production capacity and a larger number of ponds were selected from five cities of Markazi Province. The mechanized tools and equipment used in these farms were identified.
Physical and chemical parameters of inlet and outlet water were measured, including dissolved oxygen, pH, nitrite, ammonia, nitrate, phosphate, and total suspended solids. Although the water quality parameters in most of the studied farms were within acceptable limits for rainbow trout culture, several factors affected farm performance. These included production level, health management, pond washing quality and frequency, improper outlet and drainage systems, lack of siphons between outlets, failure to follow appropriate harvesting patterns, and poor siphoning and drainage practices.
Overall, these management-related issues disturbed the balance of physical and chemical water parameters and reduced the practical efficiency of mechanized devices and equipment used in the farms.
