Turkish Journal of Zoology
Frogs can be added to a list of different raw materials which have sustainable economic value to their producers. Therefore, the biochemical attributes of the frogs require further scientific scrutiny. The major objective of the current study is to investigate some biochemical compositions of edible portions of Pelophylax ridibundus (Pallas, 1771) grown in different conditions. The wild frogs, semicultured frogs, and cultured frogs were investigated regarding female and male specimens, leading to six groups that were determined to investigate the biochemical features of frogs. The results show that they (all frogs in all six groups) have low lipid contents (p < 0.05). The protein contents of the frogs varied in the range of 10.54%-16.10%. The lowest ash contents were found in semicultured male and female frogs. The average moisture contents were roughly 80% for all specimens. The major fatty acids were C16:0, C18:0, C18:1n9, C18:2n6, and C20:4n6 for wild, semicultured, and cultured frogs, respectively, for both sexes, showing their respective amounts varied among groups. All in all, the results show that there exist some differences in the nutritional content of frogs grown in different

Androgenic Hormones In Crustacean Aquaculture: A Review, Muzaffer Mustafa Harlioğlu, Ardavan Farhadi̇
Androgenic Hormones In Crustacean Aquaculture: A Review, Muzaffer Mustafa Harlioğlu, Ardavan Farhadi̇
Turkish Journal of Zoology
Increased demands of the seafood market have led to the rapid growth in crustacean aquaculture production in various parts of the world. Therefore, an expansion in the knowledge of the reproductive biology of crustaceans has become more important. Hormones released from the androgenic gland (AG) in crustaceans are liable for both the separation of primary and secondary sexual features and reproductive behavior. AG removal in male crustaceans causes a transformation of the intersex animals towards the females and a degeneration of spermatids and reproductive organs. AG implantation and injection of AG extracts are common approaches for crustacean masculinization. In this …

Accordingly, this study aimed at evaluating the effect of different storing temperatures and durations on the emergence of second-stage juveniles (J2s) of the nematode populations obtained from the eastern Mediterranean (Adana and Hatay) and south-eastern (Gaziantep and Kilis) regions of Turkey. The obtained results revealed a variation in the J2s hatching profiles of the regional nematode populations. The eastern-Mediterranean and the south-eastern populations hatched at between 5 and 20 °C; however, …

In this study, toxic effects caused by the degradation of fluoxastrobin, which is a commonly used fungicide where newly synthesized manganese or sulfur-doped TiO$_{2}$ nanoparticles exist were evaluated. The characterization study of nanoparticles was performed by scanning an electron microscopy (SEM), X-ray diffractometry, Brunau-Emmet-Teller analysis, X-ray fluorescence spectroscopy, and UV-Vis (ultraviolet-visible) reflectance spectra. Subsequently, the photocatalytic performance of nanoparticles, their toxicity, and the photocatalytic degradation products of fluoxastrobin with the same nanoparticles were tested during the two development stages of Xenopus laevis. The LC$_{50}$s of fluoxastrobin were determined on test organisms, and a 5 mg L$^{-1}$ fluoxastrobin was selected to …
