In 1995, in collaboration with local Bedouin fishermen, five no-take fisheries reserves were established within the Nabq Natural Resource Protected Area, South Sinai, Egyptian Red Sea. The abundance, size structure and catch of commercially targeted groupers (Serranidae), emperors (Lethrinidae) and snappers (Lutjanidae) were investigated before the establishment of these reserves, then in 1997 and again in 2000. By 1997, these fish had shown a significant increase in mean abundance within two of the no-take reserves. By 2000 each family and three individual species (Lethrinus obsoletus, Cephalopholis argus and Variola louti) had increased in abundance in the reserves. There were significant increases in mean individual length of the serranids Epinephelus fasciatus and C. argus and of the lethrinids L. nebulosus and Monotaxis grandoculis. Meanwhile, mean recorded catch per unit effort (CPUE) within the adjacent fished areas increased by about two-thirds (P
