“…Thus, stressful conditions have been shown to reduce lysozyme and Complement activities in serum of Atlantic salmon [17,24]. This response has been previously observed in other species in which an initial decrease of lysozyme activity was followed by a further increase after two weeks [30].…”

“…The haematological parameters determined (TAG, cholesterol, glucose, BUN, ALAT and ASAT) were similar to those of the other teleost, such as European seabass and carp ( Cyprinus carpio ) (Lemaire, Drai, Mathieu, Lemaire, Carrière, Giudicelli & Lafaurie 1991; Svobodová, Vykusová, Modrá, Jarkovský, Smutná 2006), but ALAT and ASAT of all the groups were significantly lower than those of Amur sturgeon ( Acipenser schrenckii ), Chinese sturgeon ( A. sinesis ) and Atlantic salmon ( Salmo salar L.) (Shi, Li, Zhuang, Nie & Long 2006; Hemre, Sagtad, Bakke‐Mckellep, Nanieli, Acierno, Maffia, Frøystad, Krogdahl & Sanden 2007). Besides, these parameters in fish showed a large annual variety (Fernandez & Planas 1980) and might be affected by bacterial infection (Acerete, Espinosa, Josa & Tort 2009). In the present study, serum glucose and ASAT were significantly reduced when FM was replaced by PM, which significantly affected the carbohydrate and protein metabolism when FM was replaced by a higher protein source with a concomitantly relatively higher carbohydrate content in substitution diets.…”

A digestibility and a growth trial were conducted in this study respectively. Firstly, the apparent digestibility coe⁄cients (ADC) of nutrients and energy in meat and bone meal, porcine meal (PM), hydrolysed feather meal, poultry by-products meal, ¢shmeal (FM), soybean meal and spray-dried blood meal were determined. In experiment 2, an 8-week growth trial was conducted to evaluate the e¡ects of the substitution of FM by PM under the digestible ideal protein concept at two protein levels in the diets of Japanese seabass, Lateolabrax japonicus. A FM-based control diet (FM diet; FM: 320 g kg À 1 , crude protein: 434.9 g kg À 1 , crude lipid: 124.6 g kg À 1 ) and three other diets were formulated to contain 115 g kg À 1 PM and only 160 g kg À 1 FM. Two diets were formulated on a crude protein basis without (PM diet) or with (PMA diet) essential amino acid (EAA) supplementation respectively. A low-protein diet was designed (LPMA diet, crude protein: 400.9 g kg À 1 , crude lipid: 96.3 g kg À 1 ) with the same level of FM and PM but with the same digestible protein/ digestible energy and EAA pro¢le as the FM diet. The results showed that nitrogen and total amino acid digestibility of the tested ingredients were ranged from 85.6% to 95.5% and from 87.6% to 95.5% respectively. Apparent digestibility coe⁄cients of protein for FM and PM were 91.2% and 95.9% respectively. In the growth trial, the weight gain rate and feed conversion ratio of ¢sh fed the PMA diet did not show a signi¢cant di¡erence from those of the control group, but were significantly higher than those of the PM and LPMA groups (Po0.05). Growth was related linearly to lysine and methionine intakes. It was shown that PM could be utilized in the Japanese seabass diet up to 115 g kg À 1 to replace about 160 g kg À 1 of FM protein under an ideal protein pro¢le. Essential amino acid de¢ciency (diet PM) or a lower protein level despite having an ideal amino acid pro¢le (diet LPMA) could not support the optimal growth of Japanese seabass.

“…Activity of the alternative complement pathway (ACP) was determined following the technique described by Sunyer et al [29] with minor modifications for ELISA plates [30]. Lysozyme activity assays (kU/mL) were performed by a turbidimetric method that uses the lysis of Micrococcus luteus (Sigma) for determination of the lysozyme activity using egg-white lysozyme as standard.…”

Cortisol is a key hormone in the fish stress response with a well-known ability to regulate several physiological functions, including energy metabolism and the immune system. However, data concerning cortisol effects on fish innate immune system using a more controlled increase in cortisol levels isolated from any other stress related signaling is scarce. The present study describes the effect of doses of cortisol corresponding to acute and chronic levels on the complement and lysozyme activity in plasma of the rainbow trout (Oncorhynchus mykiss). We also evaluated the effects of these cortisol levels (from intraperitoneally implanted hydrocortisone) on the mRNA levels quantified by RT-qPCR of selected key immune-related genes in the liver, head kidney, and spleen. For that purpose, 60 specimens of rainbow trout were divided in to two groups: a control group injected with a coconut oil implant and another group injected with the same implant and cortisol (50 μg cortisol/g body weight). Our results demonstrate the role of cortisol as a modulator of the innate immune response without the direct contribution of other stress axes. Our results also show a relationship between the complement and lysozyme activity in plasma and mRNA levels in liver, supporting the important role of this organ in producing these immune system proteins after a rise of cortisol in the fish plasma.
