Larval and adult seed consumption affected by the degree of food specialization in Amara (Coleoptera: Carabidae)
KLIMEŠ, Petr
This is the first study in which seed consumption is assessed for all larval instars and adults of ground beetles. Three species of the genus Amara were examined. Larvae of all three instars and adults were fed seeds of three plant species Stellaria media, Capsella bursa-pastoris and Taraxacum officinale in a laboratory no-choice experiment. In general, larvae showed greater food specialization and the daily specific seed consumption was comparable or even higher in larval than in adult stage. Results suggest that also carabid larvae may be very important consumers of weed seed in the field.
Comparison of growth and diet of juvenile perch (Perca fluviatilis) and pikeperch (Sander lucioperca) in ponds
SVATEK, Petr
Perch (Perca fluviatilis) and pikeperch (Sander lucioperca) are currently identified as suitable species for intensive aquaculture. Intensive pond farming in Central Europe (Czech Republic, Poland, Hungary and Austria) where these two species is used primarily for breeding and production of larval and juvenile stages, which then adapt to the conditions of controlled recirculation systems or used to produce blends for free water. The goal of my work will make the successful rearing of larvae of pikeperch and perch in a monoculture in pond conditions.
