“…Prior to use, Le was dissolved in an alkaline solution (NaOH, pH 11) to increase its solubility; (ii) a commercial synthetic humic acid sodium salt (HA), consisting of a mixture of humic acids, ammonium sulphate and adipic acid (Sigma‐Aldrich, Germany; catalogue number: H16752), which was dissolved in double distilled water prior to use; and (iii) HS‐rich water and sludge from a RAS similar to that described by Yamin et al. (). This freshwater RAS was stocked hybrid tilapia ( Oreochromis aureus (Steindachner) x Oreochromis niloticus ( L. ) ) and operated with a constant daily feed input of 0.8 kg during the experimental period.…”

“…This freshwater RAS was stocked hybrid tilapia ( Oreochromis aureus (Steindachner) x Oreochromis niloticus ( L. ) ) and operated with a constant daily feed input of 0.8 kg during the experimental period. HS‐rich sludge (Yamin et al., ) was pumped from the digestion basin of the system and dried for 72 hr at 70°C. Sludge powder was obtained by grinding the dried sludge with a 20‐mm grinder.…”

“…After 30 days, 100 fish from each treatment group were transferred to 100‐L culture tanks (25 fish per tank, four tanks per treatment), containing either water derived from a freshwater zero‐discharge RAS (Yamin et al., ) or tap water supplemented with either HA or Le. The tanks were operated at an ambient temperature of 20 ± 1°C with a daily water exchange of 33% with either RAS culture water or tap water supplemented with humic‐rich substances.…”

“…Due to the partial water reuse in these systems, organic compounds may accumulate, which eventually results in an accumulation of HS in the culture water (Leonard, Guiraud, Gasset, Cailleres, & Blancheton, ). In a recent study (Yamin, Borisover, Cohen, & van Rijn, ), HS‐like components in two zero‐discharge systems, a marine and freshwater one, were characterized by means of fluorescence spectroscopy. It was found that one of the four HS identified in the culture water of these systems could also be traced back in the blood of the cultured fish.…”

When challenged with atypical Aeromonas salmonicida subsp. salmonicida, exposure of the common carp (Cyprinus carpio L.) to different humic-rich compounds resulted in a significant reduction in infection rates. Specifically, in fish exposed to (i) humic-rich water and sludge from a recirculating system, (ii) a synthetic humic acid, and (iii) a Leonardite-derived humic-rich extract, infection rates were reduced to 14.9%, 17.0% and 18.8%, respectively, as compared to a 46.8% infection rate in the control treatment. An additional set of experiments was performed to examine the effect of humic-rich components on the growth of the bacterial pathogen. Liquid culture medium supplemented with either humic-rich water from the recirculating system, the synthetic humic acid or the Leonardite humic-rich extract resulted in a growth reduction of 41.1%, 45.2% and 61.6%, respectively, as compared to the growth of the Aeromonas strain in medium devoid of humic substances. Finally, in a third set of experiments it was found that while the innate immune system of the carps was not affected by their exposure to humic-rich substances, their acquired immune system was affected. Fish, immunized against bovine serum albumin, displayed elevated antibody titres as compared to immunized carps which were not exposed to the various sources of humic substances.

“…Yamin et al . () characterized the one‐year changes in fluorescent DOM composition in two zero‐discharge RAS systems (hybrid tilapia ( Oreochromis aureus × Oreochromis niloticus ) and gilthead seabream) by the same methods; humic‐like and proteinaceous substances were found to accumulate over time in both systems. The EEM‐PARAFAC technique was also used to quantify the content of water DOM and identify the composition and properties of water DOM in two types of intensified aquaponic systems (common carp and Chinese cabbage ( Brassica chinensis )).…”

The generation of solids by aquaculture activities has led to many problems in animal welfare, environmental quality, water treatment effects and public health, such as gill and intestinal damage, water eutrophication, system components blockages and antibiotics transfers through the food chain to human; thus, effective solid wastes management is very important. The purpose of this review is to summarize the sources, characterization methods, harmfulness, removal technologies and reutilization of solids in aquaculture water, including (i) different sources of solids, such as uneaten feed, feces and debris; (ii) solids characterization based on the general parameters, particle size distribution and chemical composition; (iii) the toxicity and detriment of solids to cultured species, the environment, aquaculture system components and human health; (iv) Solids removal, effluents solids thickening and source control techniques for better solids management; and (v) various methods for the reutilization of aquacultural solid wastes for resource value-adding. In addition to these five specific objectives, the merits and drawbacks of each method or technology and future research priorities are discussed. The present review provides an understanding of the role played by solids in aquaculture water and provides guidance for aquacultural solid wastes precision management, aquaculture practices and technological developments. Thus, solids management can be carried out based on this guidance to improve animal welfare and the stability of water treatment systems, reduce harm to the environment and public health, and enable the development of aquaculture in a sustainable way.

Impacts of nutrient loading and fish grazing on the phytoplankton community and cyanotoxin production in a shallow tropical lake: Results from mesocosm experiments

et al. 2022

Given the increasing eutrophication of water bodies in Africa due to increasing anthropogenic pressures, data are needed to better understand the responses of phytoplankton communities to these changes in tropical lakes. These ecosystems are used by local human populations for multiple purposes, including fish and drinking water production, potentially exposing these populations to health threats if, for example, an increase in toxic cyanobacterial blooms is associated with increasing eutrophication. To test the short‐term response of the phytoplankton community to the addition of nutrients (phosphorus and nitrogen, alone or in combination) and Nile tilapia, we developed an in situ mesocosm experiment in a freshwater lagoon located near Abidjan (Ivory Coast). We found that phytoplankton growth (estimated by chlorophyll‐a quantification) was highly stimulated when both nitrogen and phosphorus were added, while there was no clear evidence for such colimitation by these two nutrients when considering their concentrations in the lagoon. Phytoplankton growth was accompanied by significant changes in the diversity and composition of this community and did not lead to an increase in the proportions of cyanobacteria. However, the addition of fish to some mesocosms resulted in a drastic decrease in phytoplankton biomass and a dominance of chlorophytes in this community. Finally, these experiments showed that the addition of nitrogen, alone or combined with phosphorus, stimulated microcystin production by cyanobacteria. In addition, no evidence of microcystin accumulation in the fish was found. Taken together, these data allow us to discuss strategies for controlling cyanobacterial blooms in this tropical ecosystem.
