Species‐Specific Response of Fish Health Condition to Nutrient Enrichment in Subtropical Rivers [PDF]
Ecol EvolFish condition factor (K) can be used to evaluate the effects of eutrophication. Species‐specific responses of fish K to nutrient enrichment were detected. Nutrient enrichment significantly enhanced the K value of zooplanktivorous fish, while it did not affect the K value of omnivorous fish.
