Extract of Aloe vera (Aloe barbadensis Miller) Enhances the Growth, Protein Contents, and Gastrosomatic Index (GaSI) of Common Carp Cyprinus carpio

Abstract

Aquaculture is a growing agribusiness, and large-scale microbial infection frequently leads to considerable economic losses, as there are very few approved drugs available to counteract such a problem. Aloe vera is a natural therapeutic plant with biological activities, for example, antimicrobial, anticancer, mitigating, and immunomodulatory properties. Thus, an experiment was conducted to understand the effects of dietary Aloe vera on survival, growth performance, protein utilization, gastrosomatic index, and gut histomorphological studies in common carp in laboratory conditions. Aloe vera leaves were collected, washed, shade-dried, and homogenized to get a filtrate, which was extracted in ethanol (70%) using the Soxhlet apparatus. The carp with an average weight of 1.73 ± 0.14 g was divided randomly into 5 treatments (control and other 4 treated groups) with the extract of 0.0%, 0.2%, 0.4%, 0.8%, and 1.6% in the diet with 3 replicates and the stocking density was 25 fish per each replicate. Sampling was done on the 30th, 60th, and 90th days, and the results show that percent weight gain, specific growth rate, protein efficiency ratio, and feed conversion efficiency were significantly high in the treated diet compared to the control (0.0%). Gastrosomatic index, condition factors, and gut histology found better performance in common carp group fed 0.4% and 0.8% of Aloe vera after 90 days. In conclusion, it was found that Aloe vera extract between the amount of 0.4% and 0.8% is better for fish growth for common carp.

Positional Isomeric Symmetric Dipodal Receptors Dangled with Rotatable Binding Scaffolds: Fluorescent Sensing of Silver Ions and Sequential Detection of l-Histidine and Their Multifarious Applications

“…Analyses of real samples from various water resources and food items such as peanuts, pomegranate, aloe vera, milk, and mushrooms were carried out to test the recovery capacity of fluorescence probes SDO , SDM , and SDP against Ag + metal ions. The contents were extracted before usage, and the extracted products were investigated by the spiking and recovery techniques. − Water from various resources was collected from Nallurvayal, Coimbatore, Tamil Nadu, India, and food products were purchased from a local supermarket in Coimbatore, Tamil Nadu. The extraction process of the samples was carried out successfully by blending, crushing, and drying techniques.…”

Efektivitas dan Potensi Herbal untuk Peningkatan Pertumbuhan Benih Lele dumbo (Clarias gariepinus)

“…Lidah buaya juga dapat memperbaiki profil protein serta rasio albumin dan globulin yang menunjukkan tingkat kekebalan pada ikan mas meningkat. Secara histomorfologi, indek dan profil kinerja organ viscera usus lebih baik yang diindikasikan dengan pertumbuhan vili dan morfofisiologi ikan mas yang 225 meningkat dibanding kontrol (Khanal et al, 2021). Selain pertumbuhan, Aloe vera juga mampu meningkatkan efisiensi dan menurunkan konversi pakan yang lebih baik dibanding bawang putih.…”

A Mini- review : Effect of Phyllantus niruri L. on Growth and Health of Fish

“…Researches have shown that several medicinal plants are successfully used as supplement to trigger growth and feed conversion in fish and shrimp, including garlic [42], turmeric [43], black cumin [44], Aloe vera [45], Andrographis paniculata [46] and so on. Likewise P. niruri apart from being an antibacterial, antioxidant and immunostimulant, can also trigger fish growth.…”
