Yeah the fins aren't very big are they! Sorry about the pic. I tended to photograph them in the landing net so I could get them back as soon as possible. Funny thing is, this was the most male looking one out of 13 I caught! That means 13 female tench!
Look at the lips on this one too! Very big, look swollen or damaged?
Definitely female. At this time of year you will find a lot of same sex tench run together but when then temps are good for breeding you can sometimes find a single female will have several males in attendance.
To some extent, it depends on the water. However, I can't think of any water I've fished where the number of males caught even came close to matching the females. Since the 11th of May, I've had forty tench. Only four or five have been male.
I thought you’d some mysterious Tench / carp hybrid there Zerkalo. The shadow from your net made your Tench look to have more defined scales. I do need to pay specsavers a visit.
It’s a female by the way.
Easiest way to remember the difference is that males are far more bashful than females - their pelvic fins almost covering the vent whilst the females leave it all on show - also there's a pronounced 'bump' on the side of the fin where it's attached to the body of the fish.
Not the best photo but the bottom fish is male, the other two female.
