I suppose if you wanted you could make the @ into a niche, about fishing though... and if you don't have a good knowledge about fishing it won't really go anywhere.
The name itself doesn't hold much more value than $2-5.
The Kik, I don't think seeing the fact that it is applications with an s... would go for higher than $5 too.
i had this @ a few months ago and sold it for 20, i believe its been passed around since then so probably $15-20 decent niche for fishing and such, i personally dont see much value on the kik though
