The Effect of Acute Erythromycin Exposure on the Swimming Ability of ZebraFish (Danio rerio) and Medaka (Oryzias latipes).
International journal of environmental research and public health, 2020Co-Authors: Jiabo ZhangAbstract:Erythromycin is a widely used antibiotic, and erythromycin contamination may pose a threat to aquatic organisms. However, little is known about the adverse effects of erythromycin on swimming ability. To quantify erythromycin-induced damage to Fish swimming ability, Oryzias latipes and Danio rerio were acutely exposed to erythromycin. The swimming ability of the Experimental Fish was measured after exposure to varying doses of erythromycin (2 µg/L, 20 µg/L, 200 µg/L, and 2 mg/L) for 96 h. Burst speed (Uburst) and critical swimming speed (Ucrit) of Experimental Fish significantly decreased. In addition, gene expression analysis of O. latipes and D. rerio under erythromycin treatment (2 mg/L) showed that the expression of genes related to energy metabolism in the muscle was significantly reduced in both species of Fish. However, the gene expression pattern in the head of the two species was differentially impacted; D. rerio showed endocrine disruption, while phototransduction was impacted in O. latipes. The results of our study may be used as a reference to control erythromycin pollution in natural rivers.

Study on the swimming ability of endemic Fish in the lower reaches of the Yangtze River: A case study
Global Ecology and Conservation, 2020Co-Authors: Zilong Zhao, Ruifeng Liang, Yuanming Wang, Quan Yuan, Zhiguang ZhangAbstract:Abstract The swimming abilities of Spinibarbus hollandi, Siniperca chuatsi, Siniperca loona, Odontobutis sinensis and Rhinogobius giurinus were tested in this study, including induced swimming speed (Uind), critical swimming speed (Ucrit) and constant acceleration test speed (UCAT). The results showed that the Uind of the Experimental Fish in the Huishui River ranged from 5 to 30 cm/s. The average Ucrit of Fish was 68.2 cm/s and 5 times the average Uind. The average UCAT was 97.6 cm/s and 7 times the Uind. The swimming speed of Fish is related to their body size. The results showed that the swimming speed was more correlated with the shape than the body length of Fish. The relationships between the three speeds and the shape of the Experimental Fish were U ind = 9.809 S 0.128 U crit = 37.954 S 0.185 , and U CAT = 58.418 S 0.099 . The differences in Uind between the five Fishes were not obvious, while there were significant differences in Ucrit and UCAT between the five Fish species. The results of this study suggested that Spinibarbus hollandi, Siniperca chuatsi, and Siniperca loona have stronger swimming abilities than Odontobutis sinensis and Rhinogobius giurinus.

Nutritional evaluation of decapsulated cysts of fairy shrimp (Streptocephalus dichotomus) for ornamental Fish larval rearing
Aquaculture Research, 2003Co-Authors: C S Velu, Natesan MunuswamyAbstract:The suitability of decapsulated cysts of the fairy shrimp, Streptocephalus dichotomus as a sole diet was evaluated for the ornamental angelFish Pterophylum scalare larvae. Brine shrimp, Artemia sp., and microworms, Panagrellus redivivus, were used as comparison foods. The results indicate an appreciable weight gain of 15.22±1.69 mg and a growth (length) of 0.876±0.03 cm in Experimental Fish fed decapsulated fairy shrimp cysts compared with the growth and weight of Fish fed other foods. The influence of the Experimental diets was further reflected in the composition of fatty acid and amino-acid profiles of the Experimental Fish. AngelFish larvae readily consumed the decapsulated cysts and utilized them efficiently during the early days of exogenous feeding.

Preliminary Studies on the Suitability of a Fairy Shrimp Streptocephalus dichotomus as Live Food in Aquaculture
Journal of the World Aquaculture Society, 1994Co-Authors: Ethiraj Balaji Prasath, Natesan Munuswamy, A. K. Abdul NazarAbstract:A preliminary growth study was conducted with juvenile Oreuchromis mossambicus using a live-food Streptocephalus dichotomus. Experimental Fish showed better growth, survival and food conversion ratios, as well as a significant increase in protein (12%), free sugars (34.4%) and protein bound sugars (101%). However, there was a decline in the lipid content (-3.99%). Energy budget analysis revealed that about 90% of the consumed energy (as live-food) was assimilated by the Experimental Fishes. It is likely that the Fish used 45% of the total energy assimilated for metabolic activities associated with growth.

Study on the pathogenicity of Nocardia asteroides to the Formosa snakehead, Channa maculata (Lacepède), and largemouth bass, Micropterus salmoides (Lacepède)
Journal of Fish Diseases, 1992Co-Authors: S.-c. ChenAbstract:. The Formosa snakehead, Channa maculata (Lacepede), and the largemouth bass, Micropterus salmoides (Lacepede), were given an intraperitoneal (i.p.) and/or intramuscular (i.m.) inoculation of Nocardia asteroides isolated from cultured Formosa snakehead, Typical granulomatous lesions induced by the Experimental Fish were similar to the naturally infected cases. The Formosa snakehead showed 100% and 93% mortality at 14 and 35 days after i.m. inoculation with 8 mg and 0·8 mg of bacterial suspension, respectively. The largemouth bass was slightly resistant to N. asteroides but still had 95% mortality at 35 days after inoculation (i.m.) with 8 mg bacterial suspension. The bacteria were easily reisolated from spleen and kidney of the Experimental Fish. Many typical multifocal granulomata were found at the sites of injection and the internal organs such as liver, spleen, kidneys, pancreas, intestine, gills, eyes and brain. The result indicated that the N. asteroides isolated from the field ease was pathogenic to Formosa snakehead and largemouth bass.
