“…Another study reported that dietary supplementation with azomite improved disease resistance in Mozambique Tilapia Oreochromis mossambicus against A. hydrophila (Musthafa et al. ). However, other studies have reported little or no effect of rare earth minerals on animal growth (Reinitz ; Edsall and Smith ; Dias et al.…”

“…The basal diet was supplemented with azomite (0.25% or 0.50%) or sea salt (0.5% or 1.0%). The supplementation levels were based on previously published studies (Nandeesha et al 2000;Gangadhara et al 2004; Harpaz et al 2005;Liu et al 2009Liu et al , 2011Tan et al 2014;Musthafa et al 2016). The levels of other ingredients were constant for all diets.…”

“…Furthermore, transcriptomic profiling indicated an enhanced immune response in Rainbow Trout that were fed selenium-supplemented diets compared with those that were fed a basal diet (Pacitti et al 2016), and the administration of mineral-enriched diets improved the disease resistance of Stinging Catfish Heteropneustes fossilis against Aeromonas hydrophila (Jawahar et al 2018). Another study reported that dietary supplementation with azomite improved disease resistance in Mozambique Tilapia Oreochromis mossambicus against A. hydrophila (Musthafa et al 2016).

A study was conducted to investigate the effects of dietary azomite (0.25% or 0.50%) or sea salt (0.5% or 1.0%) on the growth performance and disease resistance of Channel Catfish Ictalurus punctatus. Channel Catfish fingerlings were fed diets that were supplemented with graded levels of azomite or sea salt for 9 weeks in trial 1 and for 5 weeks in trial 2. The growth parameters (weight gain and feed conversion ratio) and survival rate were determined at the end of the feeding trials. The resistance of the fish against Edwardsiella ictaluri infection was also evaluated in those that were fed diets containing 0.5% azomite or 1.0% sea salt in trial 2. The results showed that there was no significant difference in the growth performance of the fish that were fed azomite‐ or sea salt‐supplemented diets compared with control animals (P > 0.05). The mortality rate of Channel Catfish 28 d after the E. ictaluri challenge did not differ significantly between groups receiving different dietary treatments. The results indicate that dietary supplementation with azomite or sea salt at the tested levels had no significant effect on either growth performance or disease resistance against E. ictaluri in Channel Catfish fingerlings.

“…Aeromonas hydrophila is a ubiquitous bacterial pathogen, which caused infection and several diseases like hemorrhagic septicemia, fin and tail rot in fish, especially carps [1,2]. The pathogenicity of A. hydrophila appeared to involve several extracellular products (ECPs) including aerolysin, hemolysin, enterotoxin, acetylcholinesterase, as well as a surface array protein layer [3,4]. Carp farming has become a key industry in recent decades over the world.…”

Here we described nano-polyplexes (NPs) made of oleoyl-carboxymethy-chitosan (OCMCS)/hyaluronic acid (HA) as novel potential carriers for oral gene vaccines delivery. Aerolysin gene (aerA) of Aeromonas hydrophila as microbial antigen was efficiently loaded to form OCMCS-HA/aerA (OHA) NPs. OHA NPs performed the optimal parameters, i.e. smallest (154.5±9.4nm), positive charged (+7.9±0.5mV) and monodispersed system with the N/P ratio of 5 and OCMCS/HA weight ratio of 4. Upon the introduction of HA, OHA NPs was beneficial for the DNA release in intestinal environments in comparison to OA NPs. The mean fluorescence intensity detected in Caco-2 cells incubated with OHA NPs was about 2.5-fold higher than that of OA NPs; however, it decreased significantly in the presence of excess free HA. The OHA NPs and OA NPs decreased the transepithelial electric resistance (TEER) of Caco-2 monolayers obviously and induced increasing the apparent permeability coefficient (Papp) of DNA by 5.45-6.09 folds compared with free DNA. Significantly higher (P<0.05) antigen-specific antibodies were detected in serum after orally immunized with OHA NPs than that immunized with OA NPs and DNA alone in carps. These results enable the OHA NPs might resolve challenges arising from gastrointestinal damage to gene antigens, and offer an approach applicable for oral vaccination.

“…This product is used in livestock feed as an anticaking agent and is generally recognized as safe by the U.S. Food and Drug Administration. Poultry, shrimp, and tilapia farmers have been incorporating Azomite into their livestock feeds for 20 years to improve weight gain, feed conversion, and survival (Musthafa et al 2016).…”

Azomite Application Does Not Positively Influence Water Quality, Phytoplankton Populations, or Zooplankton Populations When Preparing Mississippi Channel Catfish Nursery Ponds for Stocking

Azomite is a hydrated sodium calcium alumina silicate that is mined from a volcanic deposit in Utah. The product contains many micronutrients that may be beneficial in preparing catfish nursery ponds for stocking. In northwest Mississippi, a 5-week study was conducted to compare water quality, phytoplankton populations, and zooplankton populations in Channel Catfish Ictalurus punctatus nursery ponds treated with Azomite at 0, 50, or 100 kg/ha. The study was conducted in 0.04-ha ponds during April, when fry ponds are prepared for stocking. Azomite application did not affect ammonia concentrations. Over time, nitrite concentrations increased more in control ponds compared to Azomite-treated ponds; however, nitrite concentrations were low in all ponds. Chlorophyll-a concentrations were also unaffected by Azomite application. The pH did significantly increase with increasing Azomite application rate. Azomite application had no effects on phytoplankton or zooplankton populations. Overall, there were no beneficial effects of adding Azomite to Channel Catfish nursery ponds in northwest Mississippi.
