tailieunhanh - Infestation and effect of parasitic isopod Epipenaeon ingens ingens Nobili, 1906 on commercial shrimp species in the eastern Mediterranean: a case study of the population of brown shrimp Penaeus aztecus Ives, 1891
Monthly samples of seven species of penaeid shrimps, namely, Penaeus aztecus (Ives, 1891), Penaus hathor (Burkenroad, 1959) Penaus japonicus (Spence Bate,1888), Penaus kerathurus (Forskȧl,1775), Penaus semisulcatus (De Haan,1844), Metapenaeus monoceros (Fabricus, 1798) and Metapenaeopsis aegyptia (Galil & Golani, 1990) were collected from Antalya Bay in the Eastern Mediterranean Sea from March, 2019 through March, 2020. Except for P. aztecus and P. semisulcatus, no other shrimp species were infected with the parasitic isopod Epipenaeon ingens ingens. Of the 3043 P. aztecus shrimp inspected, 541 individuals were infected () with the bopyrid parasite E. ingens ingens. However, the annual infestation rate in recruiting year class (28 mm ˂ CL: ) was much less than in larger and sexually mature (CL ≥ 34 mm: ) individuals. |
