You can see the eye is situated quite high giving the fish a good look overhead and in front and side when searching for food such as insects that may fall on the water or other fish in front , the Barbels in the last post give the fish a good all around picture of likely prey in the bottom of their range such as yabbies,
Their eyes gives them good night vision and is adequate in the daylight for feeding.
While this fish missed the grub on this occasion it recovered and found it when I wasn’t filming.
The fish also have the ability to contort their body to hunt and also get into the tightest of spaces.
I think the fish can be described as both a opportunistic and predatory , they can be caught in the day time if you place the bait in the correct areas so the literature is wrong about being solely nocturnal when they are hungry they will act in a more opportunistic manner waiting for food to come to them rather than hunting, After having studied these fish now for a long period of time I think the ratio is about 80 percent nocturnal and 20 percent diurnal .
All up the fish is a great predator and deserves its place at the top of the food chain.
I have removed the fish from the aquarium in the shipping container for the hot months and placed it in tank 4 with three other fish it now has the chance to breed with other fish and I hope it does.
I have two blackfish in aquaria this is the smaller of the two and I just added a dozen freshwater shrimp , and I think he likes them.
Notice he left it until it was in the rocks and then felt it with his barbels.
In this second video you can see how the larger of the fish tests the worms with his barbels and when he is happy they are proper food he backs up and eats one.
As some of you know here at fishsticks we have a permit to experiment with blackfish.
these experiments have culminated in fishsticks being the first to breed river blackfish in a farm setting ie we have recovered enough young fish to justify the method in other words we have managed to farm the fish. THE FIRST.
Once we had been successful we had surplus fish so I offered these fish to fisheries for restocking however because the brood stock came from a dam and not natural water they could not go into the river systems ( genetics) so I looked around and found a lake that once had trout and redfin but apparently no longer, fisheries agreed and a survey was carried out and the survey of the lake was positive there were no protected fish no turtles no eels no trout or redfin left the local council was on board (they could see the potential) as were local farmers, a small amount of earth works was need to ensure safety of potential fishers in other words good to go except it had to be okayed by the managers of the lake which happened to be parks , parks sent it to the DWELP and they crushed the whole plan.
So we now have a situation where blackfish cannot go into any empty body of water because they might impact on the local inhabitants such as frogs etc ( funny how the trout were ok) to put juvenile fish into water that holds both rainbow and brown trout is just suicide so where can these fish go!
