“…Generally, E. ictaluri from U.S. catfish aquaculture is considered genetically and antigenically homogeneous (Bertolini et al, 1990; Griffin et al, 2011; Lobb et al, 1993; Panangala et al, 2005, 2006; Plumb & Klesius, 1988), making it an excellent candidate for disease control through vaccination. Although catfish are considered the primary host for E. ictaluri , reports of this pathogen causing disease in other cultured fish species outside the United States demonstrates an increasingly widespread pathogen distribution (Bartie et al, 2012; Dong et al, 2019; Griffin et al, 2016; Hawke et al, 2013; Liu, Li, Zhou, Wen, & Ye, 2010; Phillips, Reichley, Ware, & Griffin, 2017; Rogge et al, 2013; Sakai et al, 2008; Soto et al, 2012; Suanyuk et al, 2013; Ye, Li, Qiao, & Li, 2009). Despite the relative homogeneity of E. ictaluri reported here and elsewhere, there is evidence that immunization with some E. ictaluri variants does not confer protection against all heterologous isolates (Klesius & Shoemaker, 1997).…”

“…Outbreaks of mortality in cultured Nile tilapia can occur by certain bacteria or coinfection. Several studies recorded outbreaks threatening tilapia industry by certain bacteria, such as Aeromonas species [17,22,43], Streptococcus species [44][45][46], Francisella species [47,48], Edwardsiella species [49]. Other summer tilapia outbreaks were resulted from co-infections.…”

Nile tilapia (Oreochormis niloticus) is considered one of the top cultured fish in Egypt and the second globally. The high demand for animal protein was associated with intensive fish culturing, which resulted in the emergence of disease outbreaks causing significant losses in tilapia aquaculture among the recent years. With special reference to bacterial outbreaks, Aeromonas veronii (A. veronii) is a recently reported bacterial pathogen affecting farmed tilapia and other fish species worldwide. A. veronii has been notified as a significant threat on Nile tilapia populations resulting in heavy mortality and was recorded to have a wide range of antibiotic resistance. Subsequently, recent publications focused on immunostimulant alternatives. The previous science data on summer tilapia mortality phenomena were outlined in this review article with special reference to A. veronii as an important pathogen. Clinical and postmortem symptoms, histopathological lesions, genetic diversity, and associations with others submitted to GenBank, diagnosis, control steps, and significance to public health were highlighted.

“…In this work, the deep learning mechanism is used and the surface activity is observed by focusing on jumping of fish as well as splashing. Dong et al (2019) have focused on arise of E. ictaluri in case of hybrid red tilapia juveniles that are farmed in a cage system (floating). The diseased fish has white spots in the swollen spleen as well as head kidney.…”

PurposeFish are considered as one of the important aquatic animals in the planet. They play a vital role in the nutrient cycle. They can be considered as one of the healthy food for human beings. They can also act as a solution for some of the human health problems. If fish are affected by several diseases, they in turn provide an adverse effect on human health. Therefore, it is very much essential to protect fish from being affected by any diseases.Design/methodology/approachThis paper is mainly focused on the identification of the red spot diseased area in fish. In this work, a fuzzy rule based method (FRBAM) and triangular membership function (TMFN) is used to identify the red spot disease (RSD) in the fish by analyzing several red spot diseased fish (RSDF) images. The canny edge detector is used for intermediate processing of RSDF images.FindingsThe proposed method is able to identify the red pixels over the fish by marking the affected area with red color by using a standard RGB model.Originality/valueThe proposed method follows FRBAM and TMFN in order to detect the RSD and canny edge detector for processing of RSDF images. Finally, it is tested using ten different image sizes and the results show its better performance in terms of detection of RSD affected regions of fish and execution time.
