The metamorphosis of Solea senegalensis was studied in larvae reared at 20° C and fed four different feeding regimes. A, Artemia (4 nauplii ml −1 ); B, (2 C, mixed diet 3 mg microencapsulated diet); D, (3·7 ). Rotifers were also supplied all cases during the first days feeding. These regimes supported growth rates pre‐metamorphosis period (regime G=0·376 day ; regime G=0·253 G=0·254 G=0·162 Larvae started 9 after hatching (DAH) when 13 DAH with 11 15 D. A minimum 5·6–5·9 mm L T required...
Activity of some the main enzymes involved in protein digestion and absorption (acid alkaline proteases, leucine‐aminopeptidase, acid phosphatases) as well those amylase lipase, was assessed during larval development white sea bream Diplodus sargus . All enzyme activity detected at moment mouth opening. The variations observed profiles digestive were correlated either to developmental events, such functional start stomach (22 days after hatching), or changes nature diet. early noticeable...
The development of an inert food to replace live prey during the early stages marine fish larvae requires research in different fields and therefore a precise work strategy. Our on this subject has been carried out successive steps using gilthead seabream Sparus aurata. first step was design particle that would be well accepted ingested by free-swimming larval developmental stages. We chose microencapsulation polymerization dietary protein as most appropriate method for making particles;...
This study evaluates the effects of macroalgae Ulva ohnoi on growth and intestinal functionality integrity Solea senegalensis juveniles in a 90-day feeding trial. diet (U-5) included 5% dry U. biomass, whereas an algae-free was used as control. After being fed for 45 90 days, fish body weight recorded evaluation, biological samples were taken. The inclusion (5%) significantly affected performance sole juveniles, given that after days showed lower weight, specific gain rates than with control...
Viticulture is highly dependent on phytochemicals to maintain good vineyard health. However, reduce their accumulation in the environment, green regulations are driving development of eco-friendly strategies. In this respect, seaweeds have proven be one marine resources with highest potential as plant protective agents, representing an environmentally-friendly alternative approach for sustainable wine production. The current work follows interdisciplinary framework evaluate capacity Ulva...
Coastal protection, nutrient cycling, erosion control, water purification, and carbon sequestration are ecosystem services provided by salt marshes. Additionally, ponds offer coastal breeding a nursery habitat for fishes they provide abundant invertebrates, such as amphipods, which potentially useful resource in aquaculture. Fishmeal fish oil necessary food resources to support aquaculture of carnivorous species due their omega-3 long-chain polyunsaturated fatty acids (n-3 LC-PUFA)....
Gastrointestinal (GI) microbiota has a relevant role in animal nutrition, modulation of the immune system and protection against pathogen invasion. Interest algae as source nutrients functional ingredients for aquafeeds is increasing order to substitute conventional feedstuffs by more sustainable resources. The diet an important factor composition, have been proposed shape contribute benefits host. However, fish microbiome research still limited compared other hosts. Solea senegalensis flat...
The development of artificial feeds for marine fish larvae is demanding and, taking into account the difficulties and costs associated with rearing some fish, preliminary evaluation feed ingredients using in vitro techniques may be an alternative to vivo assays. Some proteins used microfeeds were tested examination their effect on proteases seabream larvae. Casein cuttlefish meal did not affect protease activity crude larval extracts, whereas ovalbumin produced a 60% inhibition. use pH-stat...
Two basic types of protein-walled microcapsules were developed with the aid using different preparation techniques. One type (Type A) was spherical and hard-walled, whereas other G) irregularly shaped soft-walled. The present work examined larval growth development Sparus aurata reared either these as sole food source or a mixed diet rotifers from start feeding. Larvae fed on Type A evacuated them practically intact. These larvae showed strong degeneration gut epithelium, liver pancreas died...
