WM are an interesting niche fish. If you can keep some alive in a LMB/BG pond they will be a fun addition.
Warmouth ,
Lepomis gulosus
http://www.web1.cnre.vt.edu/efish/families/warmouth.htmlReproductive Habits:
· Mature at age 1 or 2
· Spawning occurs mid-spring through summer
· Males build nests in cover
· Fecundity is 4,500-63,200 eggs per female per year
Rock Bass ,
Ambloplites rupestris http://www.web1.cnre.vt.edu/efish/families/rockbass.html Reproductive Habits:
· Mature in 3 years
· Spawning occurs April to early June in water that is 15.6-26°C
· Males fan out circular nests in shallows on coarse sand to gravel and defend the nest
· Fecundity is 2,000-11,000 eggs per female
Roanoke Bass,
Ambloplites cavifrons
http://www.web1.cnre.vt.edu/efish/families/roanokebass.htmlReproductive Habits:
· Mature in 2 or 3 years
· Spawning has not been observed
· May spawn in faster water than the rock bass (A. rupestris)
· In hatcheries, spawning occurs from mid-May to mid-June at 20-22°C
· Males construct round nests in clay and gravel near banks
· Male guards the nest and watches over the larvae
· Fecundity is 3,000-11,500 eggs per female
· Hybridizes with rock bass (A. rupestris)
TEMPO OF HYBRID INVIABILITY IN CENTRARCHID FISHES
(TELEOSTEI: CENTRARCHIDAE)
DANIEL I. BOLNICK1, AND THOMAS J. NEAR
The only crosses with total inviability in
both directions are M. salmoides X (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 .
Centrarchids also retain nonzero viability and heterosis
for much longer than most other taxa.
While relatively closely related
Warmouth is a lepomis while
Rockbass is Ambloplites rupestrus ( see above) . All Lepomis can (but may not) cross while AR can't cross with LMB or Crappie. Not all crosses will survive to adulthood (some only a few days).
