Salutary value of haruan, the striped snakehead Channa striatus – a review

Abstract

Murrel namely Channa striatus or haruan contains all essential elements to maintain good health and to recover the lost energy after prolonged illness. The fatty acid composition (% of total fatty acid) indicated the abundant presence of C16:0 fatty acid as 30% and the other major fatty acids were C22:6 (15%), C20:4 (19%), C18:1 (12%) and C18:0 (15%). Haruan contains arachidonic acid (C20:4) as 19.0%, a precursor for prostaglandin and thromboxane biosyntheses. Both fatty and amino acids are important components for wound healing processes. Both the fillet and mucus extracts of haruan were found to exhibit a concentration dependent antinociceptive activity. In vitro antioxidant activity was higher in Channa roe protein hydrolysate than in Labeo roe protein hydrolysate in both DPPH radical scavenging and ferric reducing power. Protein content of roe concentrates (RPC) was found to be 90.2% (Channa) and 82.5% (Lates). Water absorption, oil absorption, foam capacity, stability and emulsifying capacity were found to be higher in Channa RPC than in Lates RPC. Characterization of protein hydrolysates from muscle and myofibrillar samples of haruan showed different kinetic and proteolytic activities. The skin extract of haruan influences the serotonergic receptor system thus they can function as an anti-depressant. Thus, haruan is the best example for food as medicine.

Modulation of the innate immune responses in the striped snakehead murrel, <i>Channa striata</i> upon experimental infection with live and heat killed <i>Aeromonas hydrophila</i>

“…The striped snakehead murrel, Channa striata is one of the economically important freshwater fish (US$ 8-10 per kg) that contributes 13% of the marketable airbreathing fish of India (Jawahar et al, 2016). It is considered as a valuable food fish not only because of its deliciousness but also of its medicinal value especially, the wound healing properties after surgical operations and reduction of the post-operative pain (Mohd and Abdul Manan, 2012;Haniffa et al, 2014).…”

Innate and adaptive immune molecules of striped murrel Channa striatus

“…Skin mucus is found to have bactericidal activity against A. hydrophila (19.5 ± 2 mm), Pseudomonas aeruginosa (28 ± 2.9 mm) and Vibrio anguillarum (24.5 ± 2.4 mm), while the intestinal mucus exhibited a strong inhibition against A. hydrophila (16 ± 1.4 mm), P. aeruginosa (29 ± 3.2 mm), V. anguillarum (18.3 ± 1.5 mm) and Vibrio fischeri (21.5 ± 1.8) (Haniffa et al . ). Acidic extract of snakehead mucus was reported to have antibacterial activity against few human pathogens such as Bacillus subtilis , Klebsiella pneumoniae and P. aeruginosa .…”

“…Cardiotoxic factor II (CTF‐II) from skin extract has hypotensive effect and cardiotoxic property through modulating the level of cardiac marker enzyme creatine phosphokinase and creatine phosphokinase MB (Haniffa et al . ). Loganathan et al .…”

“…They also stated that the arachidonic acid present in the mucus is acts as an enhancer of other antiseptic agents especially morphine. Cardiotoxic factor II (CTF-II) from skin extract has hypotensive effect and cardiotoxic property through modulating the level of cardiac marker enzyme creatine phosphokinase and creatine phosphokinase MB (Haniffa et al 2014). Loganathan et al (2013a) studied the activity of lysozyme, protease, alkaline phosphatase and esterase of mucus and suggested that among the enzymes analysed, protease was found to have high activity.…”

“…Sedangkan pada ikan air tawar lainnya seperti Korean catfish (Silurus asotus) dengan bobot 300-400 g/ekor memiliki kadar omega-3 EPA sebesar 2,7-3,7% (b/b) dan DHA 4,4-9,4% (b/b) (Hwang et al, 2006); ikan lele (Clarias sp.) dengan bobot 200-250 g/ekor memiliki kadar omega-3 EPA 0,96% dan ikan lele dengan bobot 100 g/ekor memiliki kadar DHA 3,14% (Ningsih, 2013); kadar omega-3 EPA pada ikan mujair (Oreochromis mossambicus Peters) berkisar antara 1,87-2,28% dan DHA 4,22-4,66% (Partina, Indra, & Undang, 2015); dan kadar omega-3 DHA pada ikan gabus (Channa striatus) 15,18% (Haniffa, Paul, Kumaresan, & Abdul, 2014). Minyak ikan yang pada umumnya memiliki kandungan omega 3 (EPA) cukup tinggi tersebut bisa bermanfaat untuk menjaga kesehatan dan mencegah beberapa penyakit degeneratif seperti jantung, kanker, diabetes, dan sebagainya (Nugroho et al, 2014).…”
