Embryology of the spider crabs Leurocyclus tuberculosus (H. Milne-Edwards & Lucas 1842) and Libinia spinosa (H. Milne-Edwards 1834) (Brachyura, Majoidea).
The embryonic development of the spider crabs Leurocyclus tuberculosus and Libinia spinosa was divided into five periods based on the differentiation of: (I) cleavage, (II) embryonic primordium, III) optic lobes, (IV) optic lobes pigmented and (V) chromatophores presence. Different traits such as spines, setae and telson morphology distinguish the two species from period III until hatching. Egg...
متن کاملThe effect of flow and morphology on boundary layers in the scleractinians Dichocoenia stokesii (Milne-Edwards and Haime) and Stephanocoenia michilini (Milne-Edwards and Haime).
Mass transfer characteristics of scleractinian corals are affected by their skeletal morphology and the concentration gradients that develop as a consequence of the interactions of their morphology and biomass with the overlying seawater. These interactions can have a profound effect on coral metabolism. In this study, boundary layer characteristics were compared between different size colonies...
متن کاملReproductive biology of swimming crab, Charybdis hellerii (A. Milne-Edwards, 1867) in coastal waters of the Persian Gulf (Hormuzgan province)
This study was conducted to determine some aspects of reproductive biology of the Indo-Pacific swimming crab, Charybdis hellerii (A. Milne-Edwards, 1867) in coastal waters of the Persian Gulf (Hormozgan province) from June 2015 to May 2016. The results showed that the annual sex ratio is F: M=1:1.3, with 57.4 % males. All the five stages of ovarian development of C. hellerii were observed throu...
متن کاملNeuroendocrine regulation and pesticidal impact on freshwater crab, Barytelphusa guerini (H. Milne Edwards).
The extensive use of pesticides to control agricultural pests poses a serious threat to many non-target organisms of the aquatic environment such as the freshwater crab, B. guerini. The deleterious influence of the pesticide causes physiological, biochemical, histological and such other disorders in the animal exposed. In the present study impact of an organophosphate pesticide, monocrotophos a...
متن کاملProbiotic Effects of Lactic Acid Bacteria Against Vibrio Alginolyticus in Penaeus (Fenneropenaeus) Indicus (H. Milne Edwards)
Cell free extracts of four strains of Lactic acid bacteria (LAB) viz. Lactobacillus. acidophilus, Streptococcus.cremoris, Lactobacillus bulgaricus –56 and Lactobacillus bulgaricus –57 inhibited growth of Vibrio alginolyticus in nutrient broth. The antagonism of LAB to Vibrio alginolyticus was further confirmed by streak plating wherein suppression of growth of Vibrio was obtained. Juveniles of ...
