Summary
The lifecycle of pumpkinseed, (Lepomis gibbosus (L.)), was studied to obtain information on age, growth and reproduction. Using scales, back‐calculation of length indicates a fast growth rate during the first 2 years of life (69.8–83.4 mm, respectively) after which it decreases. The length: weight relationship of a sample of 600 pumpkinseed specimens can be described by the equation W= 12.078 10‐6. FL3.131 for both sexes. The average condition factor (K) of all pumpkinseed was 1.40, with a range of 1.39 to 1.41. The studied species were sexuall mature at age 1 + The relationship between fecundity F) and fork length (FL) was F = 0.02438 FL3.08. The mean absolute fecundity was 7169 eggs, ranging from 1122 to 12 293 eggs; mean diameter = 0.8 mm. Spawning occurred from the second half of June until the end of July at water temperature 22–25°C.
