Sea run trout tactics – Craig Vertigan

Sea run trout tactics – Craig Vertigan

During the trout off-season I tend to spend a bit of time chasing bream, to continue getting a fishing fix, and spend time tying flies and dreaming about the trout season to come. It’s a time to spend doing tackle maintenance, stocking up on lures and dreaming up new challenges and goals for the trout season ahead. When the new season comes around I usually spend the first few months targeting sea runners. Sea run trout are simply brown trout that spend much of there lives out to sea and come in to the estuaries for spawning and to feed on whitebait and the other small endemic fishes that spawn in late winter through spring. Mixed in with the silvery sea runners you can also expect to catch resident fish that have the typical dark colours of a normal brown trout as well as atlantic salmon in some of our estuaries that are located near salmon farm pens. Living in Hobart it is quick and easy to do a trip on the Huon or Derwent and is a more comfortable proposition compared to a trip up to the highlands with snow and freezing winds to contend with.

Rock Lobster Plan - Some thoughts

The rock lobster fishery is in decline. The biomass has reduced and is still in decline. The total catch must be reduced to allow the biomass to rise.

There is real thought amongst recreational fishers that Government, and more particularly the fisheries department does no more than give recreational fishers lip service.

True there has been meetings statewide, and whilst all 230 commercial rock lobster fishers were notified with a letter regarding meetings, 21 400 recreational were only aware of these meetings if they happened to read the newspaper - and saw the Public Notice. This is not good enough.

Recreational marine fishers pay well over a million dollars in licence fees, and it would be wise to fully engage these people - not just take their money.

Recreational fishers take around 63% of the allocation to the recreational sector. That is 107t of 170t allocated. Rec potting is 83% of effort and 61% of catch. Diving is 15% of effort and 33% of catch. 60% of rec catch is for east/southeast region is less than 20 metres of water and this is said to be roughly equivalent to the commercial catch from this area as well. Current catch is about .75 lobsters per day for pots and 2.25 for divers. The average annual rec catch is 6-7 rock lobsters. Anecdotally some rec divers take a large number of rock lobster. 

Commercial fishing catch is around 1500t, but a reduction has been agreed 09/10 of 3.5% and a further 10% 10/11. After that reductions are dependent on the annual monitoring. However uncaught commercial quota has been allowed to be carried over to the following year.

Commercial fishers are allowed to retain a small quantity of rock lobster for personal use. (1 rock lobster per day’s fishing up to a maximum of 5, if the trip is 5 days or longer). The personal possession rock lobster is recorded in a logbook and may not be sold. In 2007/8 the total number of lobsters retained under this provision was 4430 which equates to about 22 lobsters per vessel. 

The Rock Lobster Management Plan Review Discussion Paper makes several proposals.

Most of the commercial proposals are rubbery, but this sector has the most to lose, and certainly has the most affect on biomass on the whole. Cuts, in some way, will be essential if the industry is to remain viable.

Some options we (Tasmanian Fishing and Boating News - www.tasfish.com) have discussed with interested parties include (in no particular order):

Reduce commercial catch (already flagged),

Remove carry over provisions in commercial catch (should be done immediately),

Reserve water less than 20 metres for recreational fishers - not practical. Water can be more than 20 metres deep only 5 metres from the shore in many areas,

Reduce bag/possession limits for all recs. (Unlikely to have any affect as current catch is .75 RL per day) Was reduced from 10 to 5 per day in 1998. It would be extremely unlikely for the bag/possession limit to ever go up in the rec sector when the fishery improves,

Reduce bag/possession limits for dive fishers. Remember divers are 15% of rec effort, but 33% of catch ( would have an immediate effect, but hard to police once divers are out of the water),

Disallow hookah (surface supplied air) diving for taking RL. Why? It does allow fishers to spend a long time underwater, allows large, breeding RL to be taken, give opportunity to target hard to reach RL, allows large numbers of RL to be taken. Would have immediate effect, and reasonably easy to police. See appendix 1 below.

Disallow hookah, but allow SCUBA. Somewhat limits access to small caves, and whilst hookah is unregulated in any way SCUBA has quite good controls and regulations.

Introduce maximum size limits for female RL (to allow breeding and predation on centropstephanus sea urchins) for recs, and/or commercial (has some merit, but sizes may vary in different areas),  

Introduce recreational tags - A huge cost, a huge waste of tags would occur and would be almost impossible to manage. New tags would be required each year. Remember the average catch is 6-7 so how many tags would each fisher be allowed - 5, 10, 30 50 or more?

A quote from a website

"Hookah allows me to venture to remote locations and provisions me with air to enable diving for basically unlimited periods. I can travel to areas that most other amateur divers do not frequent and thereby discover fishing grounds that yield large numbers of big fish. These sorties offshore caused me to progress from flybridge style boats to a long-range trawler. xxxx provides a wonderful dive platform. Diving for crayfish usually requires squeezing into their caves. The smaller the diver, the more crayfish he can catch. When I commenced diving, I soon figured that taking a deep breath, removing my scuba tank, wriggling into a cave, catching a crayfish, then looking for my tank to allow me to resume breathing, was probably not going to result in a long and productive life.
