A.L. Muthuraman, K.G. Adiyodi


The semen of Penaeus indicus, a tissue free homogenate of seminal vesicle is a viscous fluid with specific density 1.57 and pH between 7 and 8. It contains 79.6% water and 20.4% solids. The important biochemical constituent of P. indicus semen is trichloroacetic acid precipitable proteins. Seminal sugars are made up of oligosaccharides mainly trehalose and polysaccharides. Lipids formed 4.2% of total wet semen while free amino acid quantity was low
