TL;DR: The relation between length (L) and weight (W) was estimated for 32 species representing 12 families of fishes from six water resources in the Marmara region, Turkey and the parameter b ranged from 2.66 to 3.56.

TL;DR: With the exception of smaller size at maturity, all traits were higher in populations from artificial water bodies than those inhabiting running waters, suggesting gibel carp is required to exert more reproductive effort to invade natural ecosystems than artificial waters.

TL;DR: The results suggest that the decline in the reservoir's native cyprinid populations is likely due to a combination of degrading environmental conditions and a disparity in reproductive effort, with introduced C. gibelio invasion facilitated by gynogenetic reproduction and an observed interference with native fishes during spawning.

TL;DR: Relationships between total, fork and standard lengths belonging 19 families from Aegean and Marmara coast of Turkey were presented for 42 fish species and they were all linear.

TL;DR: Mussels were demonstrated to have evolved strong defenses to bitterling parasitism in the area of ancient sympatry, but have no such defenses in the large areas of Europe where bitterling are currently invasive.
