Levende gresshopper eller sirisser i stavanger
Hei alle sammen,
Jeg er en biolog som forsker laks og jeg leter etter levende gresshopper eller sirisser for å mate laksene mine. Jeg leter etter en butikk eller en person som selger den i nærheten av Stavanger/Sandnes.
Har dere noen råd?
Med vennlig hilsen,
Daan

Takk for rådet Livsforvalteren og Juliane!
Min norsk er ikke bra nok for å fortelle om min forskning på detalj (jeg er nederlansk og har bare bort i norge for et år), men jeg kan fortelle lit om min forskning på engelsk som dere er interessert .
I am interested in the behaviour of hatchery-reared salmon for restocking purposes. Millions of salmonids are reared in Norwegian hatcheries every year with the purpose to release them into nature to increase population size (for example, if a dam has been built). However, if you rear a fish in an aquarium, it won't learn how to survive in the wild. For example, it doesn't recognize predators and prey.
I am investigating if salmon can be better prepared for a life in the wild by using alternative rearing methods. For example, I rear them in enriched environments: tanks with low fish densities and many structures such as rocks and plants. Now I want to see if growing up in this environment will make fish more curious to approach new, more realistic food types, such as live crickets. Also, I will release some of these fish in the wild to see if it improves their chances of survival.

I guess you already have thought about copepods (hoppekreps) and similar? I recently set up a fry-tank with a leaf-substrate from outside my house and after a week or so I discovered a theeming colony amongst the leaves And from what I have read decomposing leaves themselves can function as fry-food. But your project focus on larger fish, maybe?
Have you considered banana-flies? They can also be ordered, at least in my local shop.
I'd be happy to keep reading any updates Good luck!

It's interesting to read that you have used your own grown copepods . I am focussing on larger parr, a few months pre-smolt, so I would need something a bit bigger. I need feed that floats on the surface of the tanks, to standardize the movement of the prey and to be able to film properly.
I am picking up some crickets from the shop today, curious to see if they do the job. Will keep you posted
