SE QLD Jungle Perch Fishery RescueFolks, who here would like the opportunity to visit a Queensland Impoundment and have the chance to tangle with a 3 kilo Jungle Perch, or on blustery windy day, drive up into the hinterland and match wits with a wily, wild Jungle Perch in a crystal clear mountain stream, even if you live in highly populated Brisbane?
If you have answered yes to these questions, you can help make it happen.
Research into Jungle Perch is close to producing these results, for us, our kids and our grandkids but the researchers need help. They have achieved amazing advances so far but require a little more funding to get over the line. By sending an email showing our support we can help them, help us.
To get on board and support this worthwhile venture please send an email to the following with a few words of support.

Recently I was fortunate enough to attend a fish stocking association meeting, where Michael Hutchison gave a presentation on the work completed so far by the Bribie Island Research Division on a project aimed at the mighty Jungle Perch. As most of us are aware, the Jungle Perch used to be able to be found in most streams along the Queensland coastline and in years gone by, was a favourite target species for fresh water anglers in the know. Unfortunately pollution, barriers across water ways and destruction of habitat has nearly done this iconic species in and has been causing local extinctions up and down the Queensland Coastline.
A few years ago Michael and his team put together a plan to do two things, firstly to ensure the survival and reintroduction of the species to its historical range; secondly to develop the ability to stock the species in impoundments as another draw card for Queensland’s fabulous fresh water fisheries. With a great deal of support the team managed to secure 2 years of funding to begin research on a species of which very little was known and also attempt to meet the long term goals of the project. Given the level of knowledge available at that time it was a very ambitious attempt.
Amazingly though, in two years, the scientists working on the project have managed to complete an absolutely stunning amount of work on this species, ticking off many milestones and have come tantalisingly close to achieving the projects aims. Herein lies the problem, the funding has finished and the group has to apply for more to complete the project and this is in no way assured of succeeding. As anglers we can fortunately influence the outcome of this situation by writing a short email supporting the application for sufficient funds to complete this important project. Simply address, the email To Whom It May Concern and write a short message urging the recipient to give whatever support is necessary to allow the completion of the Jungle Perch project.
Initially the team had to identify where Jungle Perch used to exist, this involved researching historical documents and interviewing anglers to gain anecdotal evidence. The result of this showed Jungle Perch used to exist as far south as the Richmond River in NSW. Also that not every creek and river held the species but as a result the team could identify the necessary components needed for a successful long term environment to suit Jungle Perch. It also highlighted just how many local populations have been lost to us.
During the collection of this information, Queensland Anglers, helped to identify remnant populations, which the team visited and took genetic and hormonal samples without harming these fragile populations. Importantly this data helped to show that there are three distinct populations in Queensland, not unlike Barra with Southern and Northern Populations whereby the fish are similar but don't survive very well when translocated between areas. This means if we don't act now to save the SEQ population than the chance of using a Cairns based fish to re establish a southern population is not likely to be very successful.
This stage of research also highlighted how fragile the southern populations are, one of the most successful remnant populations only has approx. 200 adult fish remaining. It isn't hard to imagine how easy it would be for this largest population to be destroyed.
The team has collected, given time to acclimate to captivity and successfully held breeding populations of all three strains of the population for two breeding seasons. Very importantly they have worked out how to collect breeding populations without threatening fragile wild groups, making commercial propagation a real possibility for the future and helps ensure the possibility of stocking our impoundments. (Just quietly 600gm wild fish held in captivity are already approaching 1.5kg suggesting Jungle Perch stocked into the food rich impoundment environments will hit the magic 3kg mark, some found in PNG wild environs weigh 5kg!!!)
What also has been done is the successful interpreting of genetic results along with behaviours to show how each strain has developed reproductive techniques to suit their climate and locality. This work effectively took up the first breeding season but now it is known that each strain requires a different salinity level to successfully reproduce. The end result of this work was shown in the second breeding season where almost 900,000 viable fertilised eggs were produced in a single session, proving again that the species is suitable for commercial production and stocking impoundments, initially only small batches of eggs could be fertilised and this process could never be cost effective.
Just achieving fertilization in an artificial environment is a great achievement, the unfertilized eggs are only about .3 of a mm and upon fertilization are only about .7 of a mm. When hatched these eggs produce fry which are very small, particularly when compared with current species which are produced for stocking such as Bass, Barra, Silvers and Goldens.
This leads to the bottle neck facing the researchers, they can collect brood stock, look after it and produce commercial quantities of fry, but onfeeding these fry to a size where they will survive is the challenge facing the project. As of right now the fry will last until day 6 before dying, with all the lead up work, the team only had time to trial 6 different approaches to ensuring survival of fry 'til the stage they are large enough for release. There is a great plan prepared to solve this problem but without our support it won't happen and this will be just another case of what could have been. Please help, it could be the next trial which solves this problem and saves this important state wide fishery.{mos_fb_discuss:2}
