Species identification methods from acoustic multifrequency information *

Contract nr: QLRT-CT-2000-02054
Project type: RS (Research and Technological Development Project)
Starting date:
Duration: 36 months
Total cost: 2,678,671 EUR
EC Contribution: 1,010,463 EUR

Research topic: 5.1.2. Sustainable fisheries and aquaculture

Abstract:
SIMFAMI will apply modern multi-frequency fisheries acoustic techniques, in addition to the single-frequency methods previously available, to establish methods for the acoustic identification of echo traces that are applicable to routine fisheries acoustic survey procedures. The project will: construct a multi-frequency echogram library from historical survey data; apply single-frequency data extraction methods for species identification; develop multi-frequency algorithms for the differentiation of fish from plankton and the identification of fish with and without swim-bladders. The developed species recognition algorithms will be implemented in standard fisheries acoustic survey analysis software. Ultimately the project will improve acoustic surveys, allow the technique to be used effectively for mackerel assessment, and enable the techniques to be carried out on platform other than research vessels.

Objectives:
The overall goal of the project is to enhance fisheries management through improved fish stock surveys by enabling the identification of fish species using acoustic methods. The project will apply modern multi-frequency fisheries acoustic techniques, in addition to the single-frequency methods previously available, and to establish methods for acoustic species identification of echo traces that are applicable to routine survey procedures.

The project will:
1) construct an echogram library;
2) apply single-frequency extraction/identification methods on multi-frequency data;
3) develop multi-frequency algorithms for the differentiation of fish from plankton and for the identification of fish (with and without swim-bladders); and
4) combine these techniques in a generic algorithm for plankton and fish stock.
