In the experiment, mineral contents of the head, caudal, central fleshy part, and spinal columns of fishes were determined by inductively coupled plasma atomic emission spectrometry. The Ca content of base fleshy part ranged from 1,682 to 5,505 mg/kg. The Ca contents of central fleshy part were found between 104 and 428 mg/kg. This value was found between 5,582 and 7,368 in the spinal column parts. The K content in general ranged from 2,411 (Carassius gibellio) and 4,419 mg/kg (Scomber scombrus). The highest potassium was found on the central fleshy part and ranged between 3,214 and 4,419. The P content was found mostly on the bones and it range between 28,833 and 34,726. The least phosphor amount was found on the central fleshy part. While the Cd content ranges between 0.019 ppm and 0.104 mg/kg, Cr content changed between 1.32 and 4.20 ppm.

Nerocila bivittata (Crustacea, Isopoda, Cymothoidae) is reported for the first time on the caudal peduncle of the Rusty blenny, Parablennius sanguinolentus (Teleostei, Perciformes, Blenniidae), collected from Samsun Coast, Black Sea, Turkey. N. bivittata parasitized 7.4% (2 of 27) of the P. sanguinolentus collected.
