I googled it but can't see anything other than how to go about it.Are there any kosher data on them to substantiate their use on C&R fish?
Ged - do you know of any (peer-reviewed) published papers on the validity of this as being safe (when performed correctly) on fish being C&R'd?Poor form, shoving tube too quickly into fish (damaging gullet), pushing tube too far into fish, filling with too much water and squirting too much water into fish. Basically being ham fisted. hno: You don't want to push food items to the back of the stomach and compact it all or even explode the stomach = dead fish.
The idea is not to squirt all the water out of the pump, short gentle squeeze of the bulb and immediate release to suck water back and any insects. It's the fish's last meal you want to know about (hence throat pump). You also don't want to be pumping air into the fish either.
I do have a small pump and also a small sieve net (when I remember to take them ) but only used for collecting insects of or in the water.
I'm afraid it's one of those procedures that needs practice getting things right, bit like chinning a pike. Though in the trout's case, it's the trout that gets it if all goes wrong. hno:
I don't know of any and can't find any Col.Ged - do you know of any (peer-reviewed) published papers on the validity of this as being safe (when performed correctly) on fish being C&R'd?
Far easier to spoon a dead fish. I do spoon dead fish that I knock for the table, a way of learning what trout eat and also being a fly tier, I will alter patterns to suit (hopefully) and give a better chance of catching. Having a basic level of entomology I think is a great help in improving your fishing and another side to enjoy. :thumbs:Is spooning or pumping (if it can be done in a safe and ethical manner) something that the more professional/successful among you recommend?
I only ask because I don't, and have never even considered it, but I might be missing out.
Should I be carrying a spoon?
Do you use them every trip, or only once in blue moon, when you are struggling for information?
Would it improve my success rate?
I probably should say I am C&R 999/1000.
Come on Bob!If you've caught a fish on a black buzzer for example, then that tells you that the fish are willing to take black buzzers. That being the case, why bother to try finding out what they are eating? What if you find bloodworms, black buzzers, corixae, olive buzzers and daphnia? Then what do you do?
