Observations on some biological characteristics of Holothuria polii and Holothuria sanctori from mediterranean EgyptAuthor(s):
Ragia Moussa and Ismiliana WirawatiAbstract:
The study presents the first reported case of Holothuria sanctori
distribution in the Egyptian Mediterranean coast and its biological characteristics, including Holothuria polii
as the most common and over-exploited holothurians in the region.
A total of 103 H. polii and
87 H. sanctori
samples were collected based on their distinctive morphometric characteristics and ossicle composition. The calcareous structures of H. polii
have the form of rugose buttons and short tables with maltese crown ossicles, rods and perforated plates, while the ossicle structures of H. sanctori
are in the form of buttons with various sizes, smooth edge and different numbers of holes. H. sanctori
was found on rocky substratum and rocky cavities at 5-22 m depth while H. polii
was sampled from rocky and sandy substratum of 2-12 m depth. Results on studies of weight frequency distribution in both species have showed the heavy impact of over fishing in the region leading to the loss of large size class individuals.Pages: 351-357 | 563 Views 24 DownloadsDownload Full Article:
