There is a close association between parthenogenesis and polyploidy. For this reason, we
undertook a karyological analysis to test whether the parthenogenetic Marmorkrebs …

The karyotype of freshwater redclaw crayfish Cherax quadricarinatus (von Martens) was
studied by examining metaphase chromosome spreads from the testis tissues. A total of 79 …

Freshwater prawns of the genus Macrobrachium are one of the important components of
circumtropical marine, estuarine, and freshwater environments. They have been extensively …

Abstract Analysis of metaphases of Palaemon serratus (Pennant, 1777) revealed a diploid
number of chromosomes with a karyotype composed of two large metacentric pairs, six …

This study seeks to determine the best method for preventing the second body (PBII)
extrusion as a means to induce triploidy in the black tiger shrimp Penaeus monodon …

In Mexico, the biology of Procambarus has been more studied than the biology of other
Cambarids because of its diversity and potential use in aquaculture. We determined the …

World production of farmed shrimp is focused on a few species. At present, the Pacific
whiteleg shrimp Litopenaeus (Penaeus) vannamei tops the list, followed by the black tiger …

The chromosomes of freshwater prawn (Macrobrachium lanchesteri) were characterized by
means of conventional Giemsa-, DAPI-, silver-staining and G-banding techniques. The …

Progress in Penaeid shrimp genetics, inbreeding and biotechnology has been slower than
fishes; perhaps one of the reasons is the lack of knowledge on fundamental aspects of their …

Within the last few years, freshwater Crayfish Procambarus clarkii (P. clarkii) has been
successfully established in various sites of the river Nile and its branches. The main aim of …
