Abstract
: Aplication of safe level of copper concentrations at short-and long-term durations for different larval stages, post-larvae, juveniles and adult stage of Macrobrachium rosenbergii are not well understood. Furthermore, the short-and long-term effects of copper toxicity on the physiological aspects, particularly oxygen consumption and ammonia excretion, effect on the growth and accumulation pattern in different tissues, biochemical composition and variations in enzyme activities are not recorded in details. Therefore, the following objectives were selected for the present study to fulfill the major lacunae existing in copper toxicity studies in M. rosenbergii including to assess (i) the tolerance limit of copper and evaluation of LC 50 at 48 and 96 hours duration through bioassay experiments in I st to XI th different larval stages, post-larvae, juveniles and adult stage of M. rosenbergii, (ii) toxicity impact of copper on water quality parameters, particularly salinity and alkalinity, (iii) the physiological stress conditions by assessing the oxygen consumption and ammonia N excretion rate in M. rosenbergii juveniles by exposing them in sub-lethal copper concentration for short-and long-term durations, (iv) the level of stress conditions by monitoring the changes occurring in the biochemical compositions and enzyme activities in gills, muscles and hepatopancreas, (v) the acute level of copper exposure on growth parameters and (vi) accumulation in selected tissues and their depuration period.
铜对十足目甲壳类动物的毒性,特别是对大brachium rosenbergii (de Man) 的毒性
:对不同幼虫期、后幼虫期、幼鱼期和成鱼期的短期和长期铜浓度安全水平的应用尚不十分清楚。此外,铜毒性对生理方面(特别是耗氧量和氨排泄量)的短期和长期影响、对不同组织的生长和积累模式的影响、生化成分和酶活性的变化也没有详细记录。因此,本研究选择了以下目标,以弥补铜对 M. rosenbergii 的毒性研究中存在的主要空白,包括:(i) 通过对 M. rosenbergii 的 Ist 至 XIth 不同幼虫期、后幼虫期、幼虫期和成虫期进行生物测定实验,评估铜的耐受极限以及 48 和 96 小时的 LC 50;(ii) 评估铜对 M. rosenbergii 不同组织的生长和积累模式的影响;(iii) 评估铜对 M. rosenbergii 不同组织的生长和积累模式的影响。(ii)铜对水质参数,特别是盐度和碱度的毒性影响,(iii)通过评估 M. rosenbergii 幼体的耗氧量和氨氮排泄率,评估其生理应激条件。(iv)通过监测鳃、肌肉和肝胰脏中生化成分和酶活性的变化,了解应激条件的程度;(v)铜暴露的急性水平对生长参数的影响;(vi)铜在选定组织中的积累及其消亡期。
