Growth Response of Cyprinus Carpio Fingerlings Fed Diets Containing Hydrothermally Processed Citrullus Lanatus Seed Meal

Abstract

Abstract:The effect of incorporating hydrothermally processed watermelon whole seeds in the diet of fish was investigated on growth, feed utilization and body composition of carp (Cyprinus carpio) fingerlings. Fish diets (35% crude protein) were formulated using water melon hydrothermally processed for 0 (DT1), 10 (DT2), 20(DT3), 30 (DT4) and 40 minutes (DT5) boiling time. Twenty fingerlings (1.50±0.00g each) were randomly allocated in triplicate to 70 liters plastic bowls, for each treatments, aeration was provided to culture bowls throughout the 12weeks feeding trial.Result of the study reveals that fish fed DT 4 (30 minutes) had the best performance in terms of mean weight gain, feed conversion ratio, feed conversion efficiency, protein efficiency ratio, apparent net protein utilization and specific growth rate (P>0.05). Hence, hydrothermal processing of watermelon seeds for 30minutes is recommended for better growth in C. carpio.

Effects of Dietary Moringa oleifera Leaf Meal as a Replacement for Soybean Meal on Growth, Body Composition and Health Status in Cyprinus carpio Juveniles

“…This result is similar to the results of Bello et al (2013), Shazali et al (2013) and who reported on fish fed diets of walnut leaves, onion bulb residues and watermelon seed meal, respectively. The values obtained in this study were higher than values reported by Tiamiyu et al (2016) on Orechromis niloticus fed Moringa oleifera leaf meal. However, this variation may be attributed to the replacement nature.…”

“…However, this variation may be attributed to the replacement nature. In the study by Tiamiyu et al (2016), soybean was replaced with Moringa oleifera leaf meal weight for weight while the present study replaced crude protein for crude protein. The study further revealed that feed conversion ratio, specific growth rate and protein efficiency ratio of the fish fed experimental diets were improved compared to the fish fed control diet.…”

“…Most of the ingredients such as fish, soybean, groundnut, cotton seed, etc. Abdel-Tawwab et al, 2018;Musa et al, 2018) are in competition with other users such as direct human consumption, poultry and terrestrial animal feed leading to price hikes of fish feed (Tiamiyu et al, 2016), hence the need for less competitive and low-price alternative such as Moringa oleifera. Plant materials as a protein source in the diet of different fish species has been investigated (Bello et al, 2013;.…”

“…However, Moringa oleifera is one of the economic plants commonly grown in tropical Africa. Moringa oleifera with about 30% crude protein and important minerals (WHO, 1986;FAO, 1990) has been tested in the diets of some fishes (Tiamiyu et al, 2016), however, there is paucity of information on its utilisation in the diet of Cyprinus carpio, hence the need for this study. Although crude protein of soybean (45%) is higher than the crude protein of Moringa oleifera leaf (25 to 30%), the high percentage of the crude protein postulates its utilisation in the diet of fish.…”

“…In line with the result of this study, Tiamiyu et al [20] demonstrated that boiling watermelon seed up to 40 min did not affect the protein content or feed utilization by C. gariepinus. However, a feeding trial with Cyprinus carpio showed a significant reduction in performance beyond 30 min of hydrothermal processing [21].…”
