Fisheries monitoring film


Queensland has a long history of
monitoring its fisheries since the early 1900s. Monitoring helps us understand the fisheries resources available for
current and future generations. We collect information from commercial
fishers, charter operators, seafood processors, recreational fishers, and
indigenous fishers, and we also do our own fishery independent surveys to assess
the status of fish stocks and the sustainability of fisheries. The primary source of data from the
commercial fishing and charter sectors comes from logbooks and vessel tracking
data. Logbooks are completed to record fisher effort and catch. Additional
information is collected for quota fisheries including accurate weights and
landing locations for each trip. Logbooks also record details of any interactions
with species of conservation interest, such as turtles, dugongs, whales, dolphins and sea snakes. The log book itself records things like
the date of your trip starting, the date of your trip ending, the catch you’ve got,
the amount of effort you put in, whether you’ve got other people on board with
you, the number of lines, the area fished, and finally, how many fish you actually
catch for the day, broken down into species as well, so it’s a pretty important
tool for recording. Commercial fishing location information is collected through vessel tracking, to be rolled out across the entire commercial fleet by
2020. Many commercial fishers, seafood wholesalers and retailers help our
scientists by providing access to commercially caught fish for collecting
length information and providing fish skeletons known as fish frames for
analysis of fish age. When the moderating fisheries come here it’s a huge benefit for them, with the amount of local fishermen that will come with all
different species so they can get all that data and education to keep on going
with all their research. It’s more of a benefit for us as we supply a lot of
restaurants, so the more fish that they monitor the better off it is for us Recreational fishers also help us gather
important fisheries data by being involved in a range of monitoring
activities. Our statewide recreational fishing surveys are conducted every few
years, and let us know how many people go recreational fishing. The survey is
conducted over 12 months, and we record when, where, and how the survey
participants fish, plus what they caught and released. We also conduct regular
surveys of recreational fishers at boat ramps and beaches across Queensland.
Participating fishers contribute to our monitoring by voluntarily providing
information about their fishing trip, and the size, species, and number of fish they
caught. During these surveys, our staff are also on hand to help identify fish
and provide information about fishery management arrangements, or any recent
changes to the rules and regulations. The Keen Angler program is another way
recreational fishers work directly with our scientists. Just as commercial fishers and seafood processors donate samples, our Keen Anglers donate their filleted
skeletons or fish frames to help our research efforts. I was donating frames in the late 1980s I’d say. I’m quite happy to help I’m naturally curious, I
like to know about my fish. If there’s any way that I can help out, well I’m more than happy with that. The fish come home, I clean them, fillet them, record all the
details and then ring fisheries. They can come and pick it up when
they want – I’ve got it in the freezer. we’re interested in collecting
biological information from the fish that people catch, both recreational and
commercial fishers, so when we bring fish samples back into the laboratory we’re
interested in collecting length information, we collect sex information,
and we also look at the otoliths or the ear bones that are held in the fish’s
head. So we’re looking at the annual growth bands on the otoliths, similar to
growth rings on a tree, and this allows us to determine how old each fish
is. So we look at this data across many years because we’re looking for trends
through time in the changes in the abundance of certain age groups in a
stock, some of those trends can be influenced by environmental parameters,
also you might find that if fishing pressure has increased you will see a
change in the prevalence of certain age groups. It’s a really cool way of being
able to routinely look at the health of a stock and the sustainability of the
fishery. The work we do with recreational and
commercial fishers is also supported by our fishery independent monitoring program. For some species it’s necessary to carry out scientifically designed surveys in
key areas, and at key times. These surveys are conducted using a specialist
research vessel or through chartering commercial vessels and operators. All the data we collect is critical to the long-term sustainability of Queensland’s
fisheries resources. Our monitoring technology and techniques are improving
all the time to ensure that accurate data is used to make well-informed
decisions about Queensland’s fisheries. You can help ensure your fishery is
assessed accurately by participating in our fisheries monitoring programs. To be
