“…Infertile eggs, water quality problems, and losses caused by pathogens, particularly fungus, have been reported in trout hatcheries (Kayış et al, 2017). Particularly, gas bubble and blue sac fry syndrome in the alevin stage of trout are commonly reported (Kayış et al, 2015;Balta and Dengiz, 2020). Various precautions and applications have been used to prevent these losses (Kayış 2019;Austin et al, 2022).…”

In this study, the effect of two Gram-positive bacteria, Lactococcus lactis and Bacillus sp., on the survival rate of rainbow trout (Oncorhynchus mykiss) eggs until larval stage. And also, effects of bacteria on some water quality criteria and blue sac fry syndrome on alevin stage of fish was investigated during this period. The bacteria contaminated on healthy trout eyed eggs during the incubation period by the immersion method. Two bacterial groups and the control group were designed in duplicate. At the end of the study (fry stage), the survival rates of the eggs were recorded. It was also investigated whether the bacteria reduced the ammonia, nitrite, nitrate and phosphate content of the water and prevented the blue sac syndrome caused by Aeromonas hydrophila. The highest survival rate was observed in trout inoculated with Bacillus sp. (92.5%), followed by L. lactis (70%), and control (45%), respectively. The highest death rates were observed during the alevin stage in all groups. In this study, it was observed that both species of bacteria contributed to the survival rate of the trout eggs during the incubation period. It was determined that both species of bacteria reduced the amount of nitrite in the water. Furthermore, with this study, Bacillus sp. was observed to suppress the effects of blue sac fry syndrome caused by A. hydrophila.

This study aimed to identify the cause of sustained mortality in freshwater angelfish (Pterophyllum scalare Schultze, 1823) kept at an ornamental fish production facility in Turkey. Parasitological, bacteriological and histopathological examination were performed on moribund hybrid angelfish individuals. The moribund fish had haemorrhaged eyes, darkened skin, scale loss, ascites and false faeces. A pale liver, splenomegaly and a thinning of the intestinal wall were observed internally. The parasitological examination revealed flagellated protozoan endoparasite Spironucleus sp. in the intestine. A number of histopathological changes were observed including lipid degeneration in the liver, hemosiderin deposits as well as granulomas in the spleen, a large number of mast cells in the lamina propria of the intestine and enteritis. Numerous Spironucleus sp. parasites were seen in the intestinal wall. According to physiological and biochemical tests, the bacterial isolates obtained from the visceral organs of some fish were identified as Citrobacter freundii. After oral metronidazole treatment, with a dose of 50 mg/kg fish daily for 5 days, a decrease in fish mortality and resumed feeding were noted. A chronic spironucleosis, which systematically affects fish by penetrating the intestinal mucosa, was identified as the cause of this sustained mortality in freshwater angelfish.

The parasite fauna of alien fish species living in the new habitats has rarely been investigated and there is still poor information about this topic. This research not only provides a thorough list of parasite taxa found in non-indigenous fish species in Turkey, but it highlights the risk of infection for both native and alien ichthyofauna. With respect of native range, exotic fishes imported into Turkey have been found to be hosts for parasities from Eurasian, Asian, and North American origins, respectively.
