“…Several works (Rivera et al, 2002;Gutiérrez-Leyva, 2006;Cruz-Suárez et al, 2009) evaluated the effect of including M. pyrifera meals in feeds for white shrimp Litopenaeus vannamei, with excellent results in terms of growth rate and survival. In the present study supplementation with polysaccharides extracts of seaweeds, M. pyrifera and U. pinnatifida showed in all treatments an acceptable survival for commercial crops (higher than 60%) (Clifford, 1994), with similar values than those obtained for other species of shrimp (Casas-Valdez et al, 2006;Cruz-Suárez et al, 2009). Studies reported that inclusion of brown algae in addition to improving growth, feed intake and feed texture, reduce dry matter loss and increase water absorption, proving to be an excellent binder for pelletized feeds (Cruz-Suárez et al, 2007).…”

ABSTRACT. Water-soluble extracts from seaweeds Macrocystis pyrifera (M) and Undaria pinnatifida (U) were prepared to use the polysaccharide bioactive fraction as functional food. Chemical analysis showed that the main components of both extracts were mannitol and fucoidans. Also in both cases minor amounts of rhamnose, glucose, xylose and arabinose were determine. Content of fucose+galactose was higher in U. pinnatifida (8.7%) than in M. pyrifera (5.9%). Extracts were used as feed additive to Artemesia longinaris at inclusion levels of 1 and 2% (M1 and M2; U1 and U2), a diet without extract was used as control. Radical scavenging activities were estimated for two extracts and for midgut gland samples of experimental animals. Scavenging activity was detected in both extracts, the signal decayed to 50 and 62% in 18 min for U. pinnatifida and M. pyrifera, respectively. After 30 days of feeding, results did not show variation of survival, but growth was improved in animals fed with U1 and U2. Supplementation with 1 and 2% of U. pinnatifida showed similar quenching capacity of homogenates than those fed with M2 with a rapid 1,1-diphenylpicrylhydrazyl (DPPH) decay at 2 min of reaction. Recommended concentration for culture A. longinaris is 2%, as it is that produce the best antioxidant capacity, although the growth performance was improved also significantly only with U. pinnatifida extract.

“…As Sargassum presents their maximum abundance, bidder size and completed their reproductive and life cycle at the end of spring, this seaweed is commonly collected then to do different experiments, as in the present research. Results about the chemical composition of Sargassum, collected at the end of spring, show the following values, protein 6.1 to 7.7%, ash 31 to 38%, crude fiber 6.5 to 9.3%, and ether extract 0.34 to 1.8% (Carrillo et al 2002, Casas-Valdez et al 2006a, 2006b). The results obtained in this study (protein 7.7%, ash 33.3%, crude fiber 6.4% and ether extract 0.45%) are similar to the ones previously mentioned.…”

Abstract:The objective of this study was to evaluate Sargassum meal as feed for sheep through the measures of in vivo digestibility, dry matter degradability, pH, ammonia and volatile fatty acids in rumen. The Sargassum algae used in this experiment were collected at the end of spring, when they are more abundant, bigger, and have completed their reproductive cycle. Four tons (wet weigth) were collected manually from the intertidal zone of La Paz bay, Baja California Sur, Mexico. These algae were sun-dried and ground in a hammer mill to obtain the Sargassum meal. Four fistulated Pelibuey sheep, were fed daily with diets containing the marine algae (MA) at different levels (0, 10, 20 and 30 %), using a 4 x 4 Latin-square design experiment. Feed intake was not affected (p>0.05). Water consumption and urine excretion increased with MA (p<0.05; r 2 =0.54 and r 2 =0.74, respectively). In all treatments dry matter digestibility was of 74%-79%, and crude protein digestibility was of 85%-88%. Acid detergent fiber (59%-65%) and neutral detergent fiber (55%-66%) digestibility were greater in all treatments with MA. Ruminal pH was greater in all groups fed with MA (p<0.05). Ammonium concentration was not influenced (p>0.05) by MA. Ruminal volatile fatty acids decreased in all MA groups (p<0.05). The marine algae Sargassum spp. can be used as a feed supplement for sheep, especially in tropical and subtropical regions where these marine algae are available. Rev. Biol. Trop. 57 (4): 1271-1281.

“…Some seaweeds have been suggested as a partial feed substitute ( Marinho-Soriano et al, 2007 ) for shrimp diet, and considered a good source of protein ( Da Silva & Barbosa, 2009 ), which represents the most expensive fraction of feed cost. In some cases, shrimp composition is modified when fed seaweeds, these changes may include lipid content and carotenoids ( Cruz-Suárez et al, 2010 ; Subhra Bikash, 2015 ), or total cholesterol ( Casas-Valdez et al, 2006 ). The optimal level of inclusion of seaweed meal in shrimp feed varies among seaweed species, but, in most cases, studies have found benefits when included not higher than 5% ( Cruz-Suárez et al, 2009 ; Rodríguez-González et al, 2014 ; Cárdenas et al, 2015 ; Yu et al, 2016 ; Schleder et al, 2017 ).…”

Two experimental feeding trials were conducted during four weeks to evaluate the use of Ulva lactuca in shrimp culture: (1) for wastewater bioremediation, and (2) using different inclusion levels of U. lactuca meal in shrimp feed. In feeding trial 1, shrimp reared under seaweed U. lactuca water exchange in a re-circulation system (SWE) resulted in similar growth and feed utilization as shrimp reared with clean water exchange (CWE). Shrimp under no water exchange (NWE) resulted in significant lower growth and higher feed conversion rate (FCR) compared to the other treatments (p < 0.05). Nitrogen compounds and phosphate in water from SWE and CWE treatments did not present significant differences during the experimental trial (p > 0.05). In feeding trial 2, U. lactuca biomass produced by wastewater bioremediation in SWE treatment were dried and ground to formulate diets containing 0, 1, 2, and 3% U. lactuca meal (0UL, 1UL, 2UL, and 3UL). Shrimp fed the 3 UL diet resulted in a significant (p < 0.05) improvement of growth and FCR, and enhanced whole shrimp lipid and carotenoid content by 30 and 60%, respectively, compared to control diet. Seaweed U. lactuca is suggested as a desirable species for wastewater bioremediation in integrated aquaculture systems, and its meal as a good feed additive for farmed shrimp.
