Oxidative Stress and Antioxidant Defenses after Long-term Fasting in Blood of Chinese Sturgeon (Acipenser sinensis)

Effect of starvation on growth, biochemical, hematological and non-specific immune parameters in two different size groups of grey mullet, Mugil cephalus (Linnaeus, 1758)

“…In the light of above results, serum lysozyme activity in starved group of both size since day 20th onwards was significantly increased than both sized fed group. This suggests that starvation does not act as a stressor on non-specific immunity system of grey mullet throughout the experiment in both sized starved groups in grey mullet in which lysozyme activity function is similar to that reported by Feng et al [22].…”

“…The best case for this is significant decrease of lysozyme activity in European eel ( [9]) after 31 days subjecting the feed deprivation and significant increase of serum lysozyme activity in juvenile Chinese sturgeon Acipenser sinensis [22] once the starvation time was increased. They suggest that lysozyme activity might vary upon species, age, size, sex and environmental factors [7,22]. In the light of above results, serum lysozyme activity in starved group of both size since day 20th onwards was significantly increased than both sized fed group.…”

“…To the best of our knowledge, recently, many researchers have dealt with hematological [7,29], biochemical [11,29,37] and immunological [7,9,22] responses of fish to starvation. The present study is the first report on grey mullet focused on the starvation impacts on metabolic and physiological responses in two different sized fish.…”

Food in the Sea: Size Also Matters for Pelagic Fish

“…On the other hand, treatment 1 displayed lower level of both d-ROMs and OXY, suggesting that sardines might cope with "poor feeding conditions" by lowering their metabolic rates to limit their living costs (O'Connor et al, 2000). Furthermore, starvation is suggested to have negative consequences on immune functions, although, such effects seem to differ between species; starvation has no or positive effect on immune responses in pacu (Gimbo et al, 2015), European eel (Caruso et al, 2010) and Chinese Sturgeon (Feng et al, 2011) but decreases the ability to cope with infection in Atlantic salmon (Martin et al, 2010) and Jade perch (Luo et al, 2013). Whether such relationship is found in sardines facing "poor feeding condition" remains to be explored, but it raises concern on the possible additive effect of long-term fasting on individual survival through immune functions impairment.…”

Short fasting and refeeding in red porgy (Pagrus pagrus, Linnaeus 1758): Response of some haematological, biochemical and non specific immune parameters

“…Only recently, attention has been paid in the pertinent literature to know the response to fasting of multiple haematological (Morshedi et al, 2011), biochemical (Barcellos et al, 2010;Furné et al, 2012;Luo et al, 2012), immunological parameters (Caruso et al, 2010 and antioxidant defenses (Zhang et al, 2008;Furné et al, 2009;Rubio et al, 2010;Bayir et al, 2011;Davis and Gaylord, 2011;Feng et al, 2011).…”
