Investigating the impact of two or more toxic chemicals on aquatic organisms is one of the main objectives of toxicological research. Microplastics (MPs) are identified as a carrier or vector for other pollutants. Therefore, the current study investigated the effects of both pyrogallol (PG) and MPs, individually and in combination, on freshwater ...

Study on the Artificial Incubation of Procambarus clarkii Embryos
The Procambarus clarkii industry currently faces four major challenges: genetic degradation, disease, unstable prices, and limited breeding methods and modes. Studies on the artificial incubation of P. clarkii embryos can help solve these problems. The purpose of this study was to screen for parameters (disinfectants, embryo stripping stage, embryo ...

The growing demand for chitin and chitosan makes it necessary to look for new sources of these polymers and to develop more environmentally friendly methods for their isolation. The subjects of the current study were chitin and chitosan extracted from shells of two crayfish species: P. leptodactylus and F. limosus.

This study investigated the effects of substituting fish meal (FM) in practical diet by chlorella meal on the growth, feed utilization, and flesh quality of Pacific white shrimp (Penaeus vannamei). First, a basal diet was prepared with 200 g/kg FM inclusion (FM‐20), and then chlorella meal was used to reduce FM inclusion to 150 g/kg (FM‐15), 100 g/kg ...
