Aquaponics production of catfish and pumpkin: Comparison with conventional production systems

Abstract

Aquaponics is known to be a smart way of producing fish and crops simultaneously; however, there is a paucity of information about the extents of this system's efficiency over other conventional methods of food production. Thus, this study was designed to evaluate the performance of a catfish–pumpkin aquaponics system in comparison with recirculatory and static aquaculture systems (for fish performance), as well as irrigated and nonirrigated systems (for pumpkin performance). Results obtained showed that the production of fish in the aquaponics system was 29% and 75% more efficient than recirculatory and static aquaculture systems, respectively. The survival of the fish was also significantly improved probably due to better water quality in the aquaponics system. With respect to pumpkin production, yield in the aquaponics system was about five times the performance in irrigated land and eleven times those in nonirrigated land. This study gives definitive evidence to support the efficiency of the aquaponics system over other conventional food production methods.

Growth performance and nutritional composition of Clarias gariepinus in flood-and-drain aquaponics coupled with three species of leafy vegetable

“…However, the high correlation between weight and length in both fish tanks indicated a highly positive relationship between these parameters across the fish tanks. These results corroborate several other studies (Atique et al, 2022;Obirikorang et al, 2021;Oladimeji et al, 2020) that reported improved weight of fish raised in aquaponics compared to those raised in conventional fishponds.…”

“…Mortality observed in the control fish tank may be due to shocks introduced by the regular complete water-changing regime, which might lead to disruption of osmoregulation and functional metabolism. (Oladimeji et al (2020) reported a significant improvement in the survival rate of C. gariepinus raised in pumpkin aquaponics compared to that of the control. The high mortality rate of C. gariepinus is a major source of revenue for farmers(Fernández Sánchez et al, 2022).…”

Análisis multivariado de suelos irrigados con aguas residuales de la acuicultura

“…Limo a 1 dS m -1 , y está de acuerdo con la NOM-021- SEMARNAT-2000(SEMARNAT, 2002. En otro estudio en donde se evaluó un suelo irrigado con aguas residuales acuícolas de manera continua, se reportó un pH de 5,55 y una conductividad eléctrica de 2,71 dS m -1 , superior a la que se tuvo en los suelos bajo estudio, lo que va a depender de la biomasa presente, el tipo de producción y del manejo de la unidad de producción acuícola, así como al suelo (Oladimeji et al, 2020).…”

South American fish species suitable for aquaponics: a review

“…Providing information on the production of South American species in aquaponics systems can encourage the implementation of these systems, and therefore help to minimize the continent's problems related to high-quality food supply and the pressure on natural resources. Compared to cage and pond-based aquaculture systems, both recirculating aquaculture systems (RAS) and aquaponics need lower volumes of water and smaller areas of land to produce fish (Oladimeji et al 2020;Lennard and Goddek 2019;Martins et al 2010). In aquaponics, some of the negative effects of fish production, such as nutrient-rich effluent discharge, can be reduced through nutrient reuse by plants and energy/nutrient recovery after waste treatment by implementing additional technologies (Goddek et al 2019a).…”
