Adaptation of digestive enzymes to dietary protein, carbohydrate and fibre levels and influence of protein and carbohydrate quality in Penaeus vannamei larvae (Crustacea, Decapoda) ArchiMer
Le Moullac, Gilles; Van Wormhoudt, A; Aquacop, Aquacop.
Activity of digestive enzymes (trypsin, chymotrypsin and amylase) was studied in relation with food in Penaeus vannamei larvae first stages. Microparticles containing casein involved the decrease of soluble protein content and enzyme activities. Specific trypsin activity but not chymotrypsin was correlated (p<1%) to casein level between 10 and 60% in microparticles. Cellulose fibres in food seemed to have little effect on digestive enzymes. Starch, between 1 and 20% in microparticles, had no influence on specific amylase activity. The effect of different feeding conditions were also tested on growth. No clear relationship between growth and enzyme is established since only trypsin is concerned in the case of a casein dose effect in the food. The protein...

An early-life hypoxia event has a long-term impact on protein digestion and growth in European sea bass juvenile. ArchiMer
Zambonino, Jose-luis; Mazurais, David; Dubuc, Alexia; Queau, Pierre; Vanderplancke, Gwenaelle; Servili, Arianna; Cahu, Chantal; Le Bayon, Nicolas; Huelvan, Christine; Claireaux, Guy.
Ocean warming, eutrophication and consequent decrease in oxygen lead to smaller average fish size. Although such responses are well-known in an evolutionary context, involving multiple generations, it appears to be incompatible with current rapid environmental change. Rather, phenotypic plasticity could provide a means for marine fish to cope with rapid environmental changes. However, little is known about the mechanisms underlying plastic responses to environmental conditions that favour small phenotypes. Our aim was to investigate how and why European sea bass that had experienced a short episode of moderate hypoxia during their larval stage subsequently exhibited a growth depression at the juvenile stage compared to the control group. We examined...

Dietary modulation of some digestive enzymes and Metabolic processes in developing marine fish: Applications to diet formulation ArchiMer
Zambonino, Jose-luis; Cahu, Chantal.
During these last 20 years, many studies have focussed on the development of the digestive tract in marine fish larvae. Most of the studies aimed at acquiring knowledge on the optimal form of dietary supply for different nutrients, in order to formulate a compound diet able to totally replace live preys in the fish larvae feeding sequence. Consequently, most of the studies aimed at describing the effect of dietary adaptation on digestive enzymes profile, the morphology of the main organs, while others aspects of the physiology of the larvae digestive tract (gut hormones, intestinal transport...) were poorly investigated. This review reports the more recent data on dietary modulation of digestive enzymes with a particular emphasis, when possible, on the...

Digestive enzyme activity and food ingesta in juvenile shrimp Litopenaeus vannamei (Boone, 1931) as a function of body weight ArchiMer
Gamboa Delgado, Julián; Molina Poveda, César; Cahu, Chantal.
A study was conducted to evaluate variations of digestive enzyme activities in Litopenaeus vannamei (Boone) reared in commercial ponds under semi-intensive conditions. Shrimp were collected at each body weight increase of 2 g. As the shrimp grew (2-12 g), significant increases in the activities of lipase and chymotrypsin were observed. The total protease activity decreased from 6 g onwards. Trypsin activity showed a peak at 6 g and amylase activity increased two-fold after 2 g. Additionally, the stomach contents were analysed microscopically for shrimp between 2 and 10 g. Plant matter contributed above 30% of the total stomach content in 6-, 8- and 10-g shrimp. Detritus represented 58% and 62% of the total stomach content in 2- and 4-g shrimp,...

Effect of dietary phospholipid levels on performance, enzyme activities and fatty acid composition of pikeperch (Sander lucioperca) larvae ArchiMer
Hamza, N; Mhetli, M; Ben Khemis, I; Cahu, Chantal; Kestemont, P.
This study was carried out to evaluate the effects of dietary phospholipid on the development and rearing performance of pikeperch (Sander lucioperca) larvae. From day 10 post-hatching, fish larvae were weaned onto three isoproteic and isolipidic formulated diets with different phospholipid (PL) levels: 1.4 (PL1), 4.7 (PL5) and 9.5% (PL9) of dry matter, as soybean lecithin. Neutral lipid (NL) with inversed gradient was incorporated in diets. Survival, growth and deformities were monitored until day 34 post-hatching, as well as intestinal enzyme activities, leucine alanine peptidase (leu-ala), aminopeptidase N (AN) and alkaline phosphatase (AP), which were used as indicators of digestive tract maturation. This study showed that PL supplementation...

Effect of lipid level in a compound diet on the development of red drum (Sciaenops ocellatus) larvae ArchiMer
Buchet, Vincent; Zambonino, Jose-luis; Cahu, Chantal.
Red drum larvae were fed from day 11 to day 24 post-hatch, with Artemia (LP group) or two isoproteinic-formulated diets with varying lipid levels, 15% (L15 group) and 30% (L30 group). The lipid fraction was composed of a mixture of cod liver oil and soy lecithin. Larvae fed Artemia exhibited the greatest length, L30 diet induced a larvae length significantly greater than that obtained with L15 diet (P < 0,05). No difference was observed in larvae survival among the three dietary groups. The increase in dietary lipid concentration led to an increase in amylase and trypsin secretion levels in 24-day-old larvae. The pancreatic secretion level measured in L30 group was close to that of LP group, suggesting that the maturation of the pancreatic functions was...

Effet de l'incorporation de farines de soja et de poisson dans l'aliment sur la croissance et les enzymes digestives de Penaeus vannamei ArchiMer
Galgani, Francois; Ceccaldi, Hubert J.; Aquacop, Aquacop.
In order to improve the formulation of diets fed to reared Penaeus vannamei, the effects of soya bean and fish meals on the growth, survival, and the characteristics of the hepatopancreas and digestive enzymes of the species were studied. Four soya bean meal concentrations (0, 5, 15, 40%), four fish meal concentrations (0, 5, 15, 30%), two forms of soya bean meal and three fish meals of different geographical origin were tested. Experimental conditions were as follows: ten individuals were placed in each tank (0.5 m2 ) and two tanks were subjected to each treatment. Food was given twice a day (08-09.00 h and 19.00 h) at 10% of the initial weight each day. For biochemical analyses, nine individuals per treatment were used for the determination of the...

Etude de la variabilité spatio-temporelle des caractéristiques physiologiques des jeunes stades de vie de la seiche Sepia officinalis L. en Manche. ArchiMer
Safi, Georges.
The common cuttlefish Sepia officinalis, is a major exploited marine resource in the English Channel. It has strong seasonal and interannual variations in recruitment. Mechanisms affecting the renewal of the stock by the arrival of new “recruits” and their number need to be better understood. Thus the study of the spatial and temporal variability of “pre-recruits” physiological characteristics was conducted in four spawning sites of the Channel [i.e. Agon Coutainville (FR), Baie de Seine (FR), Selsey (UK) and Torbay (UK)]. The studied parameters were the eggs quality and hatching rate then, the digestive and immune performance of juveniles in relation to local environmental conditions. English eggs have a delayed hatching time and higher hatching rate when...

Influence of partial substitution of dietary fish meal on the activity of digestive enzymes in the intestinal brush border membrane of gilthead sea bream, Sparus aurata and goldfish, Carassius auratus ArchiMer
Silva, Flavia; Nicoli, Jacques R.; Zambonino, Jose-luis; Le Gall, Marie-madeleine; Kaushik, Sadasivam; Gatesoupe, François-joel.
The sustainable composition of diets of high nutritional value is of the utmost importance for intensive aquaculture. Digestion and absorption of nutrients depends on the activity of the digestive enzymes, in particular those located in the brush border membrane of enterocytes, which are responsible for the final stages of breaking down and absorption of nutrients. In the present study, the substitution of fish meal by lupin or rapeseed meal in the diet was evaluated on gilthead sea bream (Sparus aurata) and goldfish (Carassius auratus). The objectives were to compare the activities of intestinal brush border enzymes in both species fed the control and experimental diets. When gilthead sea bream were fed the vegetable diets, significantly lower activities...

Influência do pH de extração na atividade de inibidores de papaína em extratos proteícos de sementes de Crotalaria pallida. Repositório Alice
SOUSA, K. R. de; ARAGÃO, V. P. M.; EGITO, A. S. do.; MATA, M. F.; ANDRADE, L. B. da S..
Inibidores de enzimas digestórias são proteínas encontradas naturalmente em animais, microrganismos e plantas, sendo de larga ocorrência em sementes de leguminosas (RYAN,1990). Plantas do gênero Crotalaria, vulgarmente conhecidas como guizo-de-cascavel, são originárias da África e foram introduzidas no Brasil com a finalidade de cultivo de cobertura de solo e fornecimento de adubo verde, sendo consideradas atualmente como plantas invasoras, em face de sua ampla disseminação natural (DIAZ et al, 2003). Pesquisas relacionadas com inibidores de enzimas proteolíticas vêm se desenvolvendo largamente nos últimos anos com o intuito de melhor entender sua estrutura, especificidade e mecanismos de ação. A maioria das pesquisas refere-se ao estudo do envolvimento...

Ontogenèse des fonctions digestives et besoins nutritionnels chez les larves de poissons marins ArchiMer
Cahu, Chantal; Zambonino, Jose-luis.
The production of fish larvae by hatchery shows an intensive increase for several species, but the specific nutritional requirements of larvae were poorly known until some years. We have conducted several experiments aimed to understand the specificities in larvae digestion, and to formulate a compound diet taking into account the differences compared to juveniles. The chosen species was the European sea bass, Dicentrarchus labrax, and the data were validated on different species. Larvae were fed live preys or experimental compound diet, especially formulated for the experiment. It appeared that pancreatic digestive enzymes, such as trypsin and amylase could be assayed in early ontogenesis, before mouth opening, and increase dramatically during the first...

Phospholipids vs. neutral lipids: Effects on digestive enzymes in Atlantic cod (Gadus morhua) larvae ArchiMer
Wold, P; Hoehne Reitan, K; Cahu, Chantal; Zambonino, Jose-luis; Rainuzzo, J; Kjorsvik, E.
The aim of this study was to evaluate the effect of dietary lipid classes (phospholipid vs. neutral lipid) and level of n-3 highly unsaturated fatty acids (HUFAs) on growth, survival and digestive enzymatic activity in Atlantic cod (Gadus morhua) larvae. Larvae were fed enriched rotifers from mouth opening and were weaned to formulated diets during a co-feeding period lasting from 17 days post hatch (dph) to 24 dph. Larvae were fed exclusively compound diets from 24 dph until the end of the experiment. Three isoproteic and isolipidic compound diets with gradually decreasing levels of DHA and EPA in the dietary phospholipid fraction (diet PL3 >PL1 >NL1) and increasing levels of total dietary neutral lipids (PL3 <PL1 <NL1) were used. Larvae fed...

Potentiel probiotique de levures productrices des polyamines dans le développement du système digestif du bar Dicentrarchus labrax et de la cabrilla arenera Paralabrax maculatofasciatus ArchiMer
Tovar, Dariel.
The interest in probiotics for aquaculture is increasing rapidly. In the present work we evaluated the potential of some yeast to induce the larvae gut maturation in sea bass larvae Dicentrarchus labrax. The production of polyamines putrescine, spermidine and spermine was quantified in ten yeast strains using high performance liquid chromatography (HPLC). Afterwards, fluorescently labelled yeast adhesion to the intestine of sea bass larvae and the spotted sand bass (Paralabrax maculatofasciatus) was evaluated by fluorescent microscopy. Two of them, CBS 8339 strain (Debaryomyces hansenii) and X2180 strain (Saccharomyces cerevisiae) produce the polyamines of our interest. The same strains showed the best adhering capabilities to the sea bass and spotted sand...

The effect of starvation on refeeding, digestive enzyme activity, oxygen consumption, and ammonia excretion in juvenile white shrimp Litopenaeus vannamei ArchiMer
Comoglio, Li; Gaxiola, G; Roque, A; Cuzon, Gerard; Amin, O.
Juveniles of the white shrimp Litopenaeus vannamei were kept Without food for between 0 to 15 clays to evaluate the impact of starvation oil physiologic state (oxygen consumption, poststarvation refeeding, index, nitrogen excretion, and O:N ratio) and digestive enzymes activity. Physiologic changes were found after 6 days of fasting, and refeeding ability declined as a result. Nevertheless. the shrimp were able to Survive 16 days Without food. Starvation Caused metabolism to drop progressively toward a basal level (21 J (.) h(-1 .) g(-1)) and a decrease in the rate of ammonia excretion, because of the catabolism of amino acids front soluble protein in the hepatopancreas. This decrease led to an increase in digestive enzymes specific activity (U/mg...

The aim of this work was to investigate the catabolic process of three kinds of dietary carbohydrates in the gut of sea bass juveniles, with the possible contribution of the intestinal microbiota to the nutrition of the host, and the subsequent effects on intermediary metabolism. A first diet contained waxy maize (99% amylopectin), a highly digestible form of starch. A second diet was less quickly digestible due to its high amylose content of resistant starch. Two other diets contained fibre instead of starch, either only cellulose as control, or also other non-starch polysaccharides brought by lupin meal. The effect of the diets on the host confirmed previous results, with the stimulation of glucose storage in the liver in sea bass fed the starchy diets,...

The effects of dietary marine protein hydrolysates on the development of sea bass larvae, Dicentrarchus labrax, and associated microbiota ArchiMer
Delcroix, Jeremy; Gatesoupe, F.j.; Desbruyeres, Elisabeth; Huelvan, Christine; Le Delliou, Herve; Le Gall, Marie-madeleine; Quazuguel, Patrick; Mazurais, David; Zambonino, Jose-luis.
Protein hydrolysate is an essential component of dry starter diets for fish larvae, as promoting healthy development. Peptides are also suitable substrates for many intestinal microbes. Five experimental diets were compared to a control diet (CONT) supplemented with a commercial fish protein hydrolysate. Each diet contained one marine protein hydrolysate, which differed by the proportion of di- and tri-peptides, and by raw materials. Two diets (HYD4 and HYD5) stimulated larval growth compared with CONT. Two other diets (HYD1 and HYD2) yielded inferior growth. HYD1 was detrimental for survival, which was associated with an up-regulation of genes involved in inflammation and antioxidative responses, while the gene coding for osteocalcin was down-regulated in...
