In several studies stating the % of male and female offspring between lepomis crosses significant differences were noted wrt GSF crosses. The authors went back and looked at the data and their best explanation was that GSF populations were tainted with other lepomis genes (very hard to find 100% pure GSF stock. If those guys (professional fisheries scientists) made the mistake then what should we expect.

My guess is that is a cross with a high % GSF. I assume the fin margins were white. See this thread which shows pics and explains how to look at gill rakers.

Here pulled this out for you guys


Here is some id info .

From Wisc. Fish ID system. You can take this info or better yet download the software and look at all the pics and descriptions etc.

Dorsal, caudal, and to a lesser extent anal fins usually darkly pigmented with faint dark blotches or light dark spots and often a light yellow/cream margin; pelvic and pectoral fins lightly pigmented to dusky. 44-51 ctenoid lateral scales. Body shape and size: Body laterally compressed and deep, somewhat elongated; oval in cross section. Typically 75-150 mm (3-6 in) TL; maximum in Wisconsin about 250 mm (10 in).

Tail, dorsal and other fins: Slightly Forked or round tail. Dorsal fin with 2 lobes, broadly joined by a membrane and appearing as one fin, the first with 9-11 spines and the second with 10-12 rays. Pelvic fins thoracic. Adipose fin absent. Anal fin with 3 spines and 9-10 rays.

GSF There are 9-12 short and thick primary gill rakers on the 1st arch.

BG
BG There are 13-16 moderately long primary gill rakers on the 1st arch.


HBG
Hybrid of green sunfish X bluegill: Notice intermediate appearance of gill rakers

Let us know what you see and find out.

These should help
