    Abstract: Two experiments (I and II) each under three different salinity levels (10, 15 and 20 ppt) were conducted to investigate the effects of addition of milkfish and substrate for periphyton development and its nutitional quality. Efforts were also made to investigate the hydrobiological parameters and growth of milkfish. Both experiments were run simult... Show More

    Abstract: Appearance of aneuploidy in the germ and somatic lines is usually associated with chromosome and genome rearrangements leading to polysomies and cancer. However, aneuploidy plays an important role in chromosome evolution and in the regulation of the ontogenetic development and phenotypic expression. The latter is known as chromosome diminutions.

    Abstract: In this study, Hylarana nigrovittata was used as specimen organism to explore antipredator behaviour. In March 2016, five adult males of H. nigrovittata were collected from its natural habitat at Lata Bayu, Baling, Kedah, Peninsular Malaysia. When these specimens released in an open area, they leaped in various directions and showed several defensi... Show More

    Abstract: In Egypt, the reuse of agricultural drainage increases the country’s available water resources by 20%. The aim of this study was to assess the impact of agricultural drainage water on accumulation of heavy metals and pesticide residues of Nile tilapia (Oreochromis niloticus) reared in earthen ponds. Six earthen ponds (2 hectare for each) in two fis... Show More
