The Feasibility of Monoculture and Polyculture of Striped Catfish and Nile Tilapia in Different Proportions and Their Effects on Growth Performance, Productivity, and Financial Revenue

Abstract

Cultivation of species of high growth rates is a key achievement of sustainable aquaculture development, with the aim of increasing animal protein per capita, maintaining food security and preserving freshwater usage. The present study was conducted to evaluate the feasibility of monoculture and polyculture of striped catfish, Pangasianodon hypophthalmus, and Nile tilapia, Oreochromis niloticus, in different proportions and their effect on growth performance, survival, productivity, feed utilization, body composition, and financial revenue. Five experimental treatments were designed as follows: monoculture of striped catfish (100%), Nile tilapia (100%) and polyculture in different proportions of striped catfish and Nile tilapia (25%:75%; 50%:50%; 75%:25%, respectively), each in three replicates. The fish feeding regime consisted of isonitrogenous (307.80 g kg−1) and isocaloric (19.27-kJ g−1) diets for 14 weeks. The results revealed that the highest growth performance, feed utilization, survival of striped catfish were obtained in monoculture, followed by polyculture of striped catfish and Nile tilapia (in low proportions) (75%:25%). The total production per m3 reached 5.41 kg m−3 in the monoculture of striped catfish, this production decreased in polyculture by 52%, 46% and 23% with 25%; 50%; 75% of striped catfish. The gross margin significantly increased, in case of striped catfish farmed in monoculture, compared to other polyculture proportions. While the gross margin per m−3 of water was 6, 0.5, 1 and 3 $ in monoculture and different polyculture proportions, respectively. Moreover, the feed cost per kilogram of protein gain significantly decreased in the monoculture of striped catfish compared to other polyculture treatments. The growth performance and survival of tilapia showed no significant difference among different treatments. In addition, the proximate chemical composition did not differ in respect to species in different studied treatments. Monoculture of striped catfish is recommended to achieve high production and improve financial revenue per water unit (m−3), for better sustainable development of aquaculture.

Impact of feed with varying crude protein (CP) levels on growth performance of different fish species cultured under similar regimes

“…The present findings strongly relate to those of Tibihika et al (2020), Hura et al (2018), Iram et al (2013) and Solomon et al (2007) who reported that increase in dietary protein level in fish diet is favorable for proper fish growth. However, contrasting findings have been reported by Aslam et al (2017), Mansour et al (2021) andIslam et al (2017) who reported that lipid and other ingredients included in diets may greatly affect the fish growth. Overall production of ponds of treatment T 2 was more than that of the T 1 and control ponds.…”

Efecto del palmiste en la nutrición de alevines de tilapia (Oreochromis niloticus)

“…El costo de las dietas experimentales se calculó en dólar de los Estados Unidos (USD). El análisis de la relación costobeneficio se calculó multiplicando los costos de la dieta por el FCA y así obtener el ahorro por concepto de alimentación de las dietas experimentales con relación al grupo control (T0), en la producción de un kg de tilapia, según Palupi et al (21) y Mansour et al (22).…”

Fish Nutritional Value as an Approach to Children's Nutrition

“…It is a valuable source of essential nutrients, especially high-quality protein and fats (macronutrients), vitamins, and minerals (micronutrients) that make a vital contribution to the world's food and nutrition security ( 3 ). As a food product, fish is of greater importance in developing countries where it accounts for 75% of the daily animal protein, referred to as “rich and poor food” as an important companion ( 4 , 5 ). Compared with other animal protein sources, fish is readily available even in poorer communities at a relatively cheaper price.…”
