We get lots of questions on Centrarchid Fishes (sunfish including lepomis (BG , RES, GSF et al) , crappie and bass), crosses (hybrids) , id and genetics. So this thread will contain info from various sources including links to prior threads. Here is a start.

An excellent book for reference

Centrarchid Fishes
Diversity, Biology, and Conservation

This edition first published 2009
Blackwell Publishing Ltd.

An outstanding into on the subject in Chpt 2 by D I Bolnick

Read this for the correct approach on the questions frequently asked.










This is one of the early studies on sunfish crosses. The text link has the data.

Here are the sex ratios (percent male) that Childers got with various hybrid crosses. The male parent is listed first. There is some variation in the numbers from other studies

Bluegill X Redear 97
Redear X Green 69
Green X Redear 48
Bluegill X Green 97
Green X Bluegill 68 (2)
Redear X Warmouth 55

TEMPO OF HYBRID INVIABILITY IN CENTRARCHID FISHES

(TELEOSTEI: CENTRARCHIDAE)

DANIEL I. BOLNICK AND THOMAS J. NEAR


the larger species tends to be

the more successful maternal parent




" The only crosses with total inviability in
both directions are M. salmoides 3 (Ambloplites rupestrus,
Pomoxis annularis, or Pomoxis nigromaculatus) at 28.94 million
years, while 10 other crosses of that age have some
viability in one or both reciprocal directions (see online Appendix).
Centrarchids also retain nonzero viability and heterosis
for much longer than most other taxa."
