“…However, food is one of the determinant factors in the synthesis of these enzymes since biochemical properties (protein, lipid, and carbohydrate concentration) of food may affect their activity (Ezquerra et al, 1997(Ezquerra et al, , 1999. Nowadays, research is focused on shrimp responses (e.g., metabolic, physiological) to dietary changes, as well as on the expression of genes responsible for such responses Chávez-Calvillo et al, 2010;Flores-Miranda et al, 2015).…”

“…Relative expression of stress (heat shock protein 70 [Hsp70]) and genes encoding for digestive enzymes (trypsin and chymotrypsin) (Stephens et al, 2012;Flores-Miranda et al, 2015) in the hepatopancreas of shrimp was measured by quantitative real-time PCR using a CFX96 system and the CFX Manager version 3.0 (Bio-Rad Laboratories, Hercules, CA, USA). We analyzed the expression of reference genes 40S-S24, β-actin, EF1α, and L21 (Wang et al, 2010;Stephens et al, 2012;Flores-Miranda et al, 2015) in order to determine their stability in the hepatopancreas tissue.…”

ABSTRACT. The effects of reducing feeding rate and molasses on water quality, growth, and gene expression of Litopenaeus vannamei were evaluated in a super intensive system with zero water exchange. A bioassay of 35 days (0,75 ± 0,22 g, 36 shrimp tank ) with treatments in triplicate was performed: I) 100% commercial feed (control group) with water exchange; II) 100% commercial feed without water exchange; III) 100% commercial feed + Bacillus licheniformis BCR 4-3 + molasses without water exchange; IV) 90% commercial feed + B. licheniformis BCR 4-3 + molasses without water exchange, and V) 80% commercial feed + B. licheniformis BCR 4-3 + molasses without water exchange. Shrimp survival, weight, nitrogenous wastes, settleable solids (SS), and the relative expression (RT-qPCR) of stress and digestive genes were determined. Shrimp survival was 100% in all treatments. The reduced diet, bioflocs, and bacilli did not affect shrimp growth. The culture conditions reduced nitrogenous wastes and modulated mRNA expression of trypsin, chymotrypsin, and heat shock protein 70. Reduced feed ration can help to maintain water quality and lower costs in intensive shrimp cultures with bioflocs.

“…However, some nutritional characteristics, such as low palatability, deficiency of some essential amino acids and the existence of antinutritional factors, limit the use of these plant ingredients in aquafeed (Gatlin et al, ). In the recent decades, many efforts including enzymolysis and fermentation have been made to improve the nutritional features of plant ingredients (Flores‐Miranda, ; Wu, Han, Qin, & Wang, ).…”

Partial replacement of fishmeal by fermented soybean meal in diets for juvenile white shrimp (Litopenaeus vannamei)

et al. 2018

As an important feed ingredient, fermented soybean meal (FSM) has been widely used in aquatic animals due to its stable sources and reasonable price. Here, we evaluated the potential for replacement of fishmeal (FM) with FSM in diet of Litopenaeus vannamei. Five isonitrogenous (410 g/kg) and isolipidic (80 g/kg) diets were formulated: a control diet containing 320 g/kg FM and four experimental diets in which FM in control diet was replaced by FSM at 10 (FSM10%), 20 (FSM20%), 30 (FSM30%) and 40% (FSM40%). An 8-week feeding trial was conducted in fifteen fibreglass tanks with 50 shrimps per tank. After 8 weeks trial, FSM20% had significantly enhanced growth performance (p < 0.05). No significant difference was found in body composition and digestive enzyme activities of all groups (p > 0.05). Through real-time quantitative PCR analysis, tor and s6k expression levels of FSM20% were significantly up-regulated (p < 0.05). Results of western blot showed that the phosphorylation of S6K was not significantly affected by different dietary treatments (p > 0.05), which suggested mTOR signalling pathway was not affected by FSM diets. Based on the above data, 20% replacement of FM with FSM was reasonable and advantageous for L. vannamei diet.

“…Among which we can highlight the small floating aquatic plants, such as duckweed (Uddin et al, 2007;Talukdar et al, 2012). This plant may benefit for the aquaculture business as a cheap and abundant source of feed ingredient (Flores-Miranda et al, 2015;Sirakov and Velichkova, 2018), given that its ability to grow rapidly on water bodies. Ansal et al, (2010) reported that the productivity of duckweeds, planted in an effective planting system reach to 12−38 tons of dry weight.ha -1 .year -1 .…”

Effect of duckweed meal dietary inclusion on growth performance and survival of African catfish fingerlings

et al. 2020

View full text Add to dashboard Cite

Currently, the use of unconventional food sources in the inclusion of fish diets is cause of great interest. The growth performance of African catfish (Clarias gariepinus) was evaluated, with the inclusion of duckweed meal (Lemna perpusilla) in four levels (0, 6, 12 and 18 %) in the diet. African catfish with an average weight of 1.27 ± 0.03 g, were distributed in a completely randomized design, with 16 experimental cages (four replicates/treatment). The fingerlings were fed for 48 days of experimentation. An analysis of variance and a Duncan´s test were performed. No significant differences were found (p< 0.05) for the first two levels evaluated, but with the rest there were differences, as the percentage of inclusion of the duckweed meal in the ration increased. Final weight was decreasing, as well as absolute growth rate, increase in daily weight, feed conversion ratio and food efficiency. Survival throughout the experiment was between 72 y 65 % in all treatments. The inclusion of duckweed meal in the diet did not affect the parameters of water quality. It was concluded that the L. perpusillase meal can be included up to 12 % in diets for African catfish fingerlings, without affecting the growth performance.
