Background. Understanding the reproduction of the spotted flounder, Citharus linguatula (Linnaeus, 1758), has been considered a major step toward understanding its population dynamics, especially, in the northern Aegean Sea. So, the presently reported study aimed to study the reproductive biology of C. linguatula and provided the first data of its fecundity. Materials and Methods. This study was carried out between September 2006 and September 2008 in Saros Bay (Northern Aegean Sea, Turkey), which had been closed to trawl fishing since 2000. The gonadosomatic index, length at maturity (L50), and absolute fecundity were analysed. Results. The elevated GSI values observed, suggested the spawning period was from September to November. The length at maturity (L50) was at 15.0 cm TL for females and 14.0 TL cm for males. The relations between the absolute fecundity and total length, total weight, and age of the spotted flounder females were estimated as Fa = 0.1878TL3.29, Fa = 58.515TW + 36.453, and Fa = 887.59A – 389.43, respectively. Conclusion. The identification of reproductive strategy is necessary to obtain a better understanding of its biology.

This study was conducted to evaluate the toxic effects of aflatoxin (AF) on the growth performance of quails, and to determine the preventive efficacy of MOLDSTOP® (calcium formate, calcium propionate, citric acid, sorbic acid, acetic acid, and carrier). A total of 60 one-day-old quails (Coturnix coturnix japonica) of both sexes were equally divided into four experimental groups each comprising of five replicates of three birds. The supplementation of diet with AF decreased significantly (P<0.001) the feed consumption. The 0.5% addition of MOLDSTOP® to the AF diet did not significantly prevent or reduce negative effect of AF on feed consumption at any time period. Light microscopic examination demonstrated that the addition of MOLDSTOP® did not decrease fat deposition caused by the toxin, and besides, an electron microscopic examination indicated the reorganisation in the endoplasmic reticulum and increase in the number of ribosomes and polisomes compared to the AF plus MOLDSTOP® group. The data indicated that the addition of MOLDSTOP® to diets containing AF did not prevent the negative effects of AF observed in the quail.
