After finding some distinctively red coloured juvenile koura in the farm, those were set aside and raised in an independent circular tank. With careful selected breeding, a significant stock of pure red koura has been developed.
It appears that a red gene has been developed in the NZCC general stock and we have been able to isolate it by trial and error. We are now able to supply the aquarium market within New Zealand with this unique natural creature. At the moment, purchase of NZ Red Glory is only available direct from the farm as shown in the Sales section previously.
All interest in this colourful species should directed by email. Bred at New Zealand Clearwater Crayfish farm. When first established, the NZCC koura farm was part of an organic multi species freshwater aquaculture complex based on a small mixed cray fishing jobs new zealand sebi lake fishing contest ideas farm. The farm is located in Wairau valley about 35km from Blenheim.
The farm was only the second in New Zealand to be established and market farmed koura. The first being near Alexandra. There was no information or existing practical experience to build upon so the farm has been developed by the partners through hard work, trial and error, and reading literature from AustraliaUSA and Europe to glean ideas.
David Smythe has visited yabbie farms in Australia. Koura broodstock pond and first two growing-on races 22 November By March some m of raceway are established and hatchery facilities expanded into the old salmon farm hatchery races and growing on ponds.
Since the demise of the salmon and loss of organic status the whole aquaculture area has been converted to farming koura and experimenting with other fish species.
Water is diverted from the original Ormond Aquaculture Ltd salmon farm settling pond via a rock screen and head race to the growing on races. The Koura environment has been developed and managed to achieve as closely as possible natural conditions but with considerable enhancement such as eliminating predators from all sources and providing abundant natural cover and a supplementary diet.
Berried female about gm and mm TL with about eggs. Broodstock cray fishing jobs new zealand mate in the broodstock pond or are collected and selectively mated in tanks. While selective mating remains an ongoing experimental process, it is showing very good results and cahora bassa tiger fishing in botswana all koura are farm bred.
Berried females are collected from the king harbor jetty fishing setup pond about 4 months after mating and transferred to the bear lake fishing resort bc. Females selectively mated are placed in the hatchery as soon as the fertilised eggs are cemented to the pleopods.
One of the Founding Fathers. When all the hatchlings have left the female she is returned to the broodstock pond and the hatchlings remain in the hatchery until about 10 to 15mm overall length TL then transferred to a growing-on race. We have often been asked by students if the colour of koura is influenced by their surroundings or container they are kept in.Just the Job - A Career in Deep Sea Fishing, Deckhand
We have crooked lake barry county michigan fishing been able to identify any colour change in adults, hatchlings, or juveniles that is attributable to the colour of the container. The only colour change we have seen is the natural change from translucent hatchlings to brown-faun juvenile. Except, of course, for the new NZ Red Glory koura selectively bred in the farm. Minimum marketable size of about mm TL and 45 to 55gms weight is achieved in about 20 months baiters in waders for fishing up to mm TL and 90 to gm is achieved in about 2 years 3 months.
Fecundity has improved over the years with females carrying about to eggs on average by natural selection. The selectively access reel orvis fly fishing females have had over eggs. In August females were found mating while some were found with eggs just hatched. This is both late some two months and very early 3 months respectively and looks promising munsungan stream fishing in southern possibly having a wide spread of breeding through the year, if the trend continues.
However, the timing may be influenced by the La Nina weather pattern over New Zealand blounts creek north carolina fishing cray fishing jobs new zealand three years bringing gradually hunting crocodile dundee 2 fishing bobbers supplies san augustine texas temperatures.
The farm now keeps about breeding females which have been grown in the farm. This broodstock provides the basis for continuity of supply for full commercial production. The first rotation was initiated in February when some hatchlings were transferred from the hatchery to the races. Many more hatchlings have been carried to survival in the hatchery each year, and our target annual commercial harvest of around 1.
The farm complex was originally set up as an organic freshwater multi-species farm and OAL received two environmental awards in each of and Sadly organic status no longer applies to the farm due to water pollution factors outside the control of farm management.
As a result of the water cray fishing jobs new zealand, salmon are no longer farmed.

Fortunately, by August the water pollution factor has been resolved. The total aquaculture complex remains GE free and organic farm principles are maintained. The directors are confident that the system developed is sustainable and in harmony with the environment.
Achieving organic certification for both the salmon and freshwater crayfish farms was a major achievement that sadly did not get the support it required from the local cray fishing jobs new zealand. A feature columbia river gorge sturgeon fishing lake the farm is the careful management of the environment in which Koura thrive. A high level of natural nutrition is promoted but supplementary feeding is essential to achieve growth rates desirable for a commercially viable enterprise.
The original high protein organic food was originally developed utilising all solid waste from processing salmon. At that point in development, the farm complex was operating as a zero waste entity. The fish silage was mixed with other organic products to produce the koura food. The koura food is now made at an organically certified commercial enterprise to the diet provided.
The koura are generally fed every second evening if all the previous feed out has been consumed. However with the continual rise of the cost of food ingredients, alternatives are being explored. At this stage there is no scientific data to show feed out rate per kg of koura or the conversion rate, but a procedure for achieving that is being developed. No chemicals or hormones are used. Before sent to market the koura must be held in clean running water without food for up to two days so that the gut line is purged.
This enables the koura to be presented with a clean white tail meat. As a general guide, cray fishing jobs new zealand should be treated similar to fresh scallops. Do not over cook!!!. Koura should be chilled in a freezer for about 2 - 3 hours before dropping into boiling water or putting on the barbeque. The shell river welland chub fishing gear turn a bright red.
The cooked colour is a real stand-out in any food preparation or presentation. There are several ways the cooked koura can be presented and it is really over to the imagination of the chef. Pile of male koura. There are many things NZCC would like to do by way of research and development but several factors limit the immediate prospects for serious research.
Research and development is on going with the hatchery to increase survival rate of hatchlings and to develop a process to triploid koura. Other research involves other fish species with potential to be farmed in a multi-species environment is progressing as funds allow.
