Summary of work: Freshwater Integrated Multi-Trophic Aquaculture (FIMTA) for Atlantic salmon (Salmo salar) hatcheries: developing a computerized visual assessment tool

Abstract from most recent presentation:
The operation of Integrated Multi-Trophic Aquaculture (IMTA) systems require the specific knowledge, developing techniques and application of computerized tools to achieve operational control, increase self-efficiency and sustainability of productive systems. A series of field, laboratory and numerical analyses were performed to identify the possibility and best location for a pilot FIMTA (aquaponics) project at different freshwater hatchery facilities. Following the protocol, a computerized visual assessment was programmed to evaluate the performance of freshwater hatcheries regarding dissolved nutrient reduction. The efficacy of treatment systems (physical, chemical and biological processes) were analysed based on innovative numerical models between different production locations within the hatcheries.

A FIMTA visual interface provides a fast and reliable way to create applications with a complete set of tools to simplify rapid application development and accelerate the management of the whole system. The data are then subjected to regulatory levels. The program contains a series of databases, which are accessible to the various objects in the software. For instance, databases are maintained for each compartment for basic information, simulation settings and water characteristics.

The FIMTA program consists of one communicational interface and other basic forms such as necessary flow and nutrients (formula and numerical methods) and efficiency potential percentages (primary-secondary and hatchery efficiency potential). Each form consists of several objects including both static and dynamic data. The necessary flow and nutrient management tool interface is a systematic process that is capable of identifying and predicting concentration of dissolved nutrients and flow in the different production locations of hatcheries. The program can create a variety of numerical techniques to identify potential efficiency strategies of effluent treatment procedures for different freshwater hatchery configurations and helping them to meet regulatory limits.
