“…In this study, copper sulfate caused an insignificant decrease in the growth rate of the Nile tilapia, which is consistent with other studies (Rabago-Castro et al, 2006;Wu et al, 2007). Our results showed that 1.5 mg copper sulfate/L may safely be exposed to the Nile tilapia for 35 days without any significant effect on the growth of the fish, and the decreases of body weight gain were also insignificant at the end of 65 and 95 days periods.…”

The objective of this study was to evaluate the effects of copper sulfate (CuSO 4 , 72 nd and 96 th hours), respectively. The effects of 1.5 mg/L dose of copper sulfate on growth rate, gross clinical observations and blood biochemical parameters of Nile tilapia were evaluated after 35, 65 and 95 days of exposure periods. The differences of growth rates between control and copper sulfate-exposed groups were not significant (P>0.05) at the end of 35, 65 and 95 days. Continuous exposure of Nile tilapia to 1.5 mg/L concentration of copper sulfate in water solution for three periods (35, 65 and 95 days) decreased the total protein, albumin, aspartate aminotransferase (AST), alanine aminotransferase (ALT), glucose (except the elevation in the exposed group at the end of 95 days period), magnesium (Mg + ²), calcium (Ca + ²), iron (Fe + ²), potassium (K + ), sodium (Na +1 ), chloride (Cl -) and phosphate values in serum. The cholesterol, low density lipid (LDL), triglyceride, globulin, creatinine, alkaline phosphatase (ALP), total bilirubin, direct bilirubin, uric acid and blood urea nitrogen (BUN) concentrations in the serum increased in copper sulfate-exposed fish. ), sodyum (Na +1 ), klor (Cl -) ve fosfatın serumdaki değerlerini düşürmüştür. Kolesterol, düşük yoğunluklu lipit (LDL), trigliserit, globülin, kreatinin, alkalin fosfataz (ALP), total bilirubin, direkt bilirubin, ürik asit ve üre azotu (BUN) konsantrasyonları bakır sülfata maruz kalan balıkların serumlarında yükselmiştir.

“…According to previous researches, the WG of channel catfish in the same life stage of present study (body weight about 14.77 g) was 161%–489% after the 10 weeks feeding trial (Gatlin & Bai, ; Lochmann, Islam, Phillips, Adam, & Everette, ; Nguyen & Davis, ; Peterson, Booth, & Manning, ; Pohlenz et al, ; Rábago‐Castro, Sanchez, Pérez‐Castañeda, & González‐González, ). The results of the present study were in agreement with those studies.…”

This study investigated the effects of dietary lysolecithin on growth performance, feed utilization and metabolic responses of channel catfish (Ictalurus punctatus). Fish (initial weight: 14.77 ± 0.45 g) were randomly fed one of five practical diets supplemented with graded levels of lysolecithin (0, 125, 250, 375 and 500 mg/kg) in quadruplicate groups for 10 weeks. Results showed that no significant differences in weight gain, condition factor and viscerosomatic index among all the treatments. Fish fed diet supplemented with 250 mg/kg lysolecithin had significantly decreased feed conversion ratio and significantly increased protein efficiency ratio compared to that fed the control diet. The group with 250 mg/kg of dietary lysolecithin had higher protein and lower lipid contents in the whole body, and lower lipid content in the liver than those in the control group. Groups supplemented with 250–500 mg/kg of dietary lysolecithin had significantly higher gastric and intestinal lipase activities than the control group. Dietary lysolecithin at the level of 250 mg/kg significantly increased the activities of Na+, K+‐ATPase, alkaline phosphatase, total antioxidative capacity, total superoxide dismutase, glutathione peroxidase and catalase and significantly decreased the content of malondialdehyde compared to the control diet. In conclusion, dietary supplementation of lysolecithin could confer benefits of feed utilization, body composition and antioxidative capacity of channel catfish.

“…However, long periods of exposure can lead to toxicity, gill damage and growth suppression (Cardeilhac and Whitaker, 1988;Moore, 2005;Rábago-Castro et al 2006). Copper has a very low therapeutic index (Boyd, 2005) and its toxicity to both fish host and I. multifiliis is known to vary widely with water chemistry parameters, particularly water alkalinity and hardness (Deilhac and Whitaker, 1988;Straus, 2008;Straus and Meinelt, 2009).…”

An assessment of the use of drug and non-drug interventions in the treatment ofIchthyophthirius multifiliisFouquet, 1876, a protozoan parasite of freshwater fish

et al. 2011

Infection by the ciliate protozoan Ichthyophthirius multifiliis Fouquet, 1876 causes significant economic losses in freshwater aquaculture worldwide. Following the ban on the use of malachite green for treating food fish, there has been extensive research aimed at identifying suitable replacements. In this paper we critically assess drug and non-drug interventions, which have been tested for use or have been employed against this parasite and evaluate possibilities for their application in farm systems. Current treatments include the administration of formaldehyde, sodium chloride (salt), copper sulphate and potassium permanganate. However, purportedly more environmentally friendly drugs such as humic acid, potassium ferrate (VI), bronopol and the peracetic acid-based products have recently been tested and represent promising alternatives. Further investigation, is required to optimize the treatments and to establish precise protocols in order to minimize the quantity of drug employed whilst ensuring the most efficacious performance. At the same time, there needs to be a greater emphasis placed on the non-drug aspects of management strategies, including the use of non-chemical interventions focusing on the removal of free-swimming stages and tomocysts of I. multifiliis from farm culture systems. Use of such strategies provides the hope of more environmentally friendly alternatives for the control of I. multifiliis infections.
