Black soldier fly (Hermetia illucens) larvae meal (BSFLM) is a novel fish feed ingredient with high crude protein content (~40% dry matter, DM). However, BSFLM also contains chitin, which might impair nutrient digestibility. To investigate the effect of chitin on digestibility and chitinase activity in fish, different contents were tested as ingredients for Nile tilapia (Oreochromis niloticus) rainbow trout (Oncorhynchus mykiss). was sieved into three size fractions obtaining contents: 0–200...

Black soldier fly ( Hermetia illucens ) larvae can convert biowaste and by-products into body mass high in protein (~40% dry matter, DM) lipid (~30% DM). However, the type of rearing substrate also affects larval composition thus its nutritional value. Hitherto, it remains unclear how to what extent be altered by substrate. This study was therefore performed examine possibilities modifying using different substrates. To investigate this, 5-days old were reared for seven days on locally...

To meet the growing demand for aquatic products, aquaculture sector is expanding, including organic aquaculture. One of main challenges in this industry development suitable fish feeds. EU regulations have made recommendations, incorporation fishmeal from trimmings. However, use such meal may pose issues due to lower protein content and elevated phosphorus concentrations that could conflict with national environmental regulations. Thus, there a pressing need innovative research formulate...

High larval and fry mortality has been a major challenge to the commercial culture of African bony-tongue ( Heterotis niloticus ). Research indicates inadequate feeding be possible cause high rates larvae/fry grown in captivity. An experiment was conducted first describe developmental stages H. eggs larvae until schooling, 6 days after hatching (DAH), at 26°C. The morphological development, survival, growth (weight gain length), swimming behavior were monitored. A follow-up trial with from...

The lobster aquaculture industry, constrained by limited access to viable and cost-effective feed sources, prompted an investigation into the potential of replacing live feeds with formulated diets for Homarus gammarus larval culture, exploring alternative protein ingredients. Four were tested on newly-hatched H. gammarus: Artemia nauplii (ART), extruded control diet krill meal fishmeal as main sources (CTRL), 15% dietary replaced shrimp waste (SWM) or black soldier fly (BSF). Results...

Limited information exists on the dietary requirements of African bony‐tongue ( Heterotis niloticus ) fry as well suitable age to wean from live prey formulated diets. These have been major challenges commercial culture species. This study assessed optimal weaning effect varying phospholipid (PL) content and long chain polyunsaturated fatty acids (LC‐PUFAs) survival, performance, digestive enzyme activity H. fry. The two diets used were be isonitrogenous, isolipidic, isoenergetic (49% CP,...

Eggs from a F1 cultured broodstock of sole were compared with eggs wild-caught breeders throughout one spawning season, to evaluate if egg quality may be affected by culture-related conditions. Fourteen batches and 17 respect fatty acid (FA) composition, size, fertilization rate hatching rate. Based on multivariate analysis the FA profiles, it was possible discriminate between culture wild inheritance. had high levels C20:1(n-9), C18:2(n-6) C18:3(n-3), whereas fish C16:1(n-7), C20:4(n-6)...

The nutritional requirements of pikeperch larvae have been sparsely examined. Dietary polyunsaturated fatty acids, arachidonic acid (ARA), eicosapentaenoic (EPA) and docosahexaenoic (DHA) may affect growth physiological stress response in marine fish larvae, but these mechanisms not received as much attention freshwater fish. Pikeperch were reared on Artemia from day 3 until 21 days posthatch. enriched with six formulated emulsions, inclusion either oil, pure olive oil (POO) or supplemented...

ZUSAMMENFASSUNG Ro 4–3816 (Diallyl‐nor‐toxiferin) ist ein neues nicht depolarisierendes Muskelerschlaffungsmittel. Dieses Derivat des Alkaloids Toxiferin C wurde experimentell und klinisch geprüft mit d‐Tubocurarin verglichen. Es bei insgesamt 400 Patienten erprobt. Bei der Prüfung Greifkraft an unbetäubten Freiwilligen sowie Ruhe‐Minutenvolumens narkotisierten Patienten, erwies sich das neue Relaxans ungefähr 1,5 mal stärker als d‐Tubocurarine. Auch klinischen Anwendung von zur...

Abstract The effects of 8 nutritional variables (Ca/P, Eicosapentaenoic acid (20:5n-3) + Docosahexaenoic (22:6n − 3) (EPA DHA), Arachidonic (20:4n 6) (ARA), Se, vitamins E, C, D and A) were investigated to identify their respective importance interactions in pikeperch larval development. In this respect, two modalities (low high levels) each variable tested through a fractional factorial experimental design allowing reduction from 256 (2 ) 16 – 4 units. Survival was significantly higher...
