Abstract
The antiparasitic effect of peracetic acid (PAA) was evaluated against an infestation of the protozoan Trichodina spp. in naturally infected juvenile domestic seventh generation (F7) Striped Bass, Morone saxatilis. Replicated treatments (n=3) consisted of 1 and 2 mg/L PAA and a control; treatments were applied every other day for 3 treatments (30 min static exposure). Infestation intensity was enumerated 20 - 24 h after each treatment by counting the number of Trichodina present in a wet mount of excised gill tissue. Neither treatment rate was able to completely eradicate the parasite, however 2 mg/L PAA resulted in a statistically significant reduction which equated to 75% reduction of observed parasites. The 2 mg/L PAA treatment regimen in the present study is proposed as a safe, environmentally friendly, and effective method for reducing the intensity of Trichodina infestations in Striped Bass.
期刊介绍：
The North American Journal of Aquaculture publishes papers on new research and practical experience in all areas of intensive and extensive fish culture. Topics include broodstock selection and spawning, nutrition and feeding, health and water quality, facilities and production technology, and the management of ponds, pens, and raceways.
The journal will consider papers dealing with ways to improve the husbandry of any aquatic species—marine or freshwater, vertebrate or invertebrate—raised for commercial, scientific, recreational, enhancement, or restoration purposes that may be of interest to practitioners in North America. Its scope includes both basic and applied science, but applied scientific endeavors—including practical experiences, descriptive studies, and other nontraditional, but pertinent works—are emphasized.
