  The fish meat is valuable foodstuff of animal source. Environment pollution also water pollution is dangerous for the health and life of organisms which live in it. Water among others can be polluted with heavy metals so, fish from that water can be used as the monitoring organisms for degree of environment pollution with heavy metals. The concentrations of heavy metals higher from allowed can make the fish as animal source, dangerous and harmful for human health. Concentrations of heavy metals (Pb, Cr, Mn, Zn, Cu and Fe) were measured in different organs (liver, kidney, intestine, spleen and skin + muscle) of grass carp (Ctenopharyngodon idella) and bighead carp (Hypophthalmichthys molitrix) and in mud and water from fish farm situated in the continental part of Republic of Croatia. All measurements were carried out by the fluorescence roentgen spectroscopy that uses energy dispersion (Energy Dispersive X-ray Fluorescence method (EDXRF). Significant difference was found between mud, water and fish organ composition (p<0.05) and those between fish tissue for lead (p<0.01) and manganese (p<0.05).

  Research was conducted on common pandora fish length 13-19 cm and body weight 26-80 g caught in the Novigrad see area (Adriatic coast, Croatia). The statistical significant (p<0.05) differences of changes in diameter of muscle fibers were determine in trunk dorsal muscle between 13-15, 15.5, 17 and 17.5 cm total body length examined fish. In the ventral muscle statistical significant (p<0.05) differences were determined only between 13-15 and 15.5 cm total length of examined fish. Very low activity of Lactic acid Dehydrogenase (LDH) and Succinic acid Dehydrogenase (SDH), moderate to high activity of acid stable Adenosinetriphosphatase (ATP) and larger amount of glycogen is found in all muscle fibers of dorsal and ventral trunk muscle and it mean that this fibers are white fast twitch glycolytic fibers and this trunk muscles are white muscle. In all investigated fish red fibers were placed superficially at the lateral side of the body as dark muscles clearly distinguished from the white ones. Muscle fiber diameter of dorsal muscle was progressive increased from 15 cm (34 g) to 19 cm (80 g) (hypertrophy) and very similar observation was in muscle fiber diameter of ventral muscle.

  Research was conducted on stargazer fish length 13-19 cm and body weight 70-115 g caught in the Novigrad sea area (Croatia). An average diameter of muscle fibers in trunk muscle dorsal of the horizontal septum (dorsal muscle) was slightly greater than in the trunk muscle ventral of the horizontal septum (ventral muscle). The greatest mean fiber diameter was measured in dorsal muscle of stargazer total length 19 cm and it was 112.33 μm and in ventral muscle 109.25 μm (diameters of muscle fibers in dorsal and ventral muscle were 41-150 μm). The smallest mean fiber diameter was measured in stargazer total length 13 cm in the dorsal muscle 70.27 μm and in ventral muscle 64.95 μm (diameters of muscle fibers in dorsal and ventral muscle were 11-120 μm). The statistical significant (p<0.05) differences were determinate for changes in diameter of muscle fibers in dorsal muscle between 15.5, 16, 17.5, 18, 18.5 and 19 cm total length. In the ventral muscle statistical significant (p<0.05) differences were determined only between 15.5, 16, 17.5 and 18 cm total length of examined fish. Very low activity of Succinic acid Dehydrogenase (SDH), Lactic acid Dehydrogenase (LDH) and alkaline stable Adenosintriphosphatase (ATP) moderate to high activity of acid stable Adenosintriphosphatase (ATP) and larger amount of glycogen suggests that muscle fibers are white fast twitch glycolytic fibers. The activity of LDH and SDH as well of the alcaline stable ATP was strong but activity of acid stable ATP was weak in red slow twitch oxidative muscle fibers. The red fibers were placed superficially at the lateral side of the body as dark muscles clearly distinguished from the white ones but in stargazer small red and intermediary muscle fibers runs as a band into white dorsal muscle. The intermediary (pink) oxidative glycolytic muscle fibers has got larger fiber diameter then red and moderate to strong activity of SDH, LDH, acid and alcaline stabile ATP. The total number of fibers of stargazer fish was increased (hyperplasia) till total length of fish reached 15.5 cm (77 g). In the some time muscle fiber diameter of dorsal muscle was progressive increased from 14 cm (74 g) to 19 cm (115 g) (hypertrophy) and very similar observation was in muscle fiber diameter of ventral muscle.
