EFFECTS OF DIETARY ZEOLITE LEVELS ON SOME BLOOD PARAMETERS OF GILTHEAD SEABREAM (Sparus aurata) JUVENILES

Abstract

Abstract:In this study, it was aimed to investigate the effects of dietary zeolite supplementations on blood parameters of gilthead seabream (Sparus aurata). Zeolite was gradually included into the diets at 0%, 1%, 2%, 3% and 4% and fed to triplicated groups of fish for 10 weeks. Dietary zeolite levels did not affect red blood cell, white blood cell and hemoglobin levels of sea bream. On the other hand, serum glucose levels were linearly decreased whereas triglyceride quadratically increased with zeolite levels. There was a significant quadratic effect of dietary zeolite on serum cholesterol and alanine aminotransferase levels. Blood urea nitrogen, aspartate aminotransferase and alkaline phosphatase levels did not change in a particular trend with dietary zeolite levels, which was the case for sodium, potassium, calcium and magnesium. The results suggest that dietary zeolite inclusion up to 4% did not lead to any health impairment in gilthead sea bream when judged from blood parameters.

Effects of Dietary Natural Zeolite (Clinoptilolite) on Growth and Some Blood Parameters of Rainbow Trout (Onchorynchus mykiss, Walbaum 1792)

“…Jawahar et al (2016) reported that different rates of dietary zeolite level elevated triglyceride and cholesterol compared to the control group in snakehead murrel. All the researchers strongly stressed that the mechanisms behind the possible effects of dietary zeolite to blood chemistry values were still unknown (Khodanazary et al, 2013;Jawahar et al, 2016;Kanyilmaz and Tekellioglu, 2016). The current experiment showed that triglyceride and VLDL levels were highest with the addition of 1% zeolite and the lowest with the addition of 2.5% compared to the control group.…”

“…Khodanazary et al (2012) reported that the addition of %2.5 zeolite had no effects on serum cholesterol levels in common carp which was parallel with this experiment. Kanyilmaz and Tekellioglu (2016) stated that different rates of dietary zeolite inclusion had a significant effect on serum cholesterol and triglycerides but no effect on BUN levels of gilthead seabream. The researchers (Kanyilmaz and Tekellioglu, 2016) also stressed that the reason for the alterations in serum cholesterol and triglycerides might be originated from absorption of short-chain fatty acids by zeolites (Ly et al, 2007).…”

“…The working mechanism of zeolites regarding growth is reported as selective adsorption of ions (Ames 1967;Mercer et al, 1970), changing feces profile and extending the passage time from the digestive tract (Lanari et al, 1996;Dias et al, 1998). Also, blood in terms of blood parameters, it was remarked (Ly et al, 2007;Kanyilmaz and Tekellioglu, 2016) that serum cholesterol and triglycerides values were affected by absorption of the short-chain fatty acids by zeolites. This study aimed to evaluate any effects of dietary natural zeolite (clinoptilolite) on rainbow trout diets on growth and some blood biochemical parameters.…”

“…Increasing industrial, agricultural and commercial activities leads to severe ecological problems and affect the organisms living in the polluted environments (Kanyılmaz et al, 2014;Kanyılmaz and Tekellioğlu, 2016). Organisms living in terrestrial and aquatic environments are often exposed to heavy metal pollution that sometimes because causing serious health problems such as cancer.…”
