Aquaculture Engineering & Waste Management

Aquacultural engineering is a multidisciplinary field of engineering that aims to solve technical problems associated with farming aquatic vertebrates, invertebrates, and algae.The design and management of these systems is based on their production goals and the economics of the farming operation. The primary solution for managing the environmental impacts of aquaculture is the management of feed. Feed and feeding systems can effectively reduce wastes resulting from the fish feed through proper management of the inputs into the culture systems.

Solid fish waste consists of head, tails, skin, gut, fish and frames.  These by products of the fish processing industry can be a great source of value added products such as proteins and amino acids, collagen and gelatin, oil and enzymes. Ecological solid waste management refers to the systematic administration of activities which provide for segregation at source, segregated transportation, storage, transfer, processing, treatment, and disposal of solid waste and all other waste management activities which do not harm the environment. Fish waste compost can be applied into farm, garden, vegetable production, field crops, trees and landscapes as soil amendment and fertilizer supplement to increase soil organic matter and nutrients, promote moisture holding ability, and then enhance production and quality.
