Abstract

Introduction
A system in Poland to monitor water treatment plants
uses mussels as bioindicators
[@FerreiraRodriguez2023].
The system, SYMBIO,
measures once per second the opening level of 8 freshwater mussels
by way of a magnet glued to each mussel
[@Prote2024].
If either half of the mussels close rapidly
or one of them remains closed for longer time,
an alarm is triggered and further laboratory tests are done
[@Nazaruk2016].
This project will implement mechanisms like the polish system.
Detecting stressful mussel behavior
The use of a mussel as biodetector requires distinction
between slow-paced valve gaping change (normal),
paused valve gaping at the closed position (resting or starved)
and rapid valve gaping change (stressed)
[@Miller2022 p. 1097; @Robson2006 p. 1200].
Detecting behavioural change to a rapid gaping pace,
measurements are needed at a much higher sampling rate
than that of the normal gaping pace.
E.g. one mussel with normal gaping pace of about 1 minute
required a sample rate of 5 seconds to detect its normal pace,
and another mussel with normal gaping pace of 3-4 minutes
required a sample rate of 0.5 seconds to detect more rapid cycles
[@Robson2009 p. 195].
Another measurement of both normal and stressed behaviour,
assuming that x-axis is in seconds (not hours as indicated),
similarly shows a need for fast sampling rate
to detect a normal pace of about 1.2 minutes
and a stressed pace faster than the visualized resolution
of about 1 second
[@FerreiraRodriguez2023 fig. 2].
