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.
