“…However, the presence of seaweed (2.5 and 5.0 kg wet weight m −3 ) in shrimp biofloc systems reduced Vibrio density (by 54–83%). Seaweed has bioactive compounds such as: β‐glucan, carotenoids, tocopherols, polyphenols, polysaccharides that can act as antioxidants and promote bioactivity against virulent and antibiotic resistant Vibrio (Peso‐Echarri, Frontela‐Saseta, González‐Bermúdez, Ros‐Berruezo & Martínez‐Garciá ; Silva, Costa et al . ).…”

An indoor trial was conducted for 42 days to evaluate water quality, Vibrio density and growth of Litopenaeus vannamei in an integrated biofloc system (IBS) with Gracilaria birdiae. Four treatments were used, each in triplicate: Control (monoculture shrimp); IBS 2.5 (L. vannamei and 2.5 kg wet weight seaweed m À3 ); IBS 5.0 (L. vannamei and 5.0 kg wet weight seaweed m À3 ) and IBS 7.5 (L. vannamei and 7.5 wet weight seaweed m À3 ). Shrimp individuals (0.34 AE 0.01 g) were stocked at a density of 500 shrimp m À3 . No water exchange was carried out during the experimental period. Molasses was added once a day as an organic carbon source to maintain the C:N ratio at 12:1. The IBS significantly decreased (P < 0.05) dissolved inorganic nitrogen (DIN) ranging from 19% to 34% (3.12-3.83 mg L À1 ), NO 3 -N ranging from 19% to 38% (2.40-3.16 mg L À1 ), Vibrio density ranging from by 8-83% (0.40-2.20 log 10 3 colony-forming units mL À1 ), and FCR ranging from by 20-30% (1.20-1.37), as compared to the control (4.73 mg L À1 , 3.93 mg L À1 , 2.40 log 10 3 colony-forming units mL À1 , and 1.74 respectively). Moreover, the IBS significantly increased (P < 0.05) crude protein in whole body shrimp, ranging from 8% to 13% (13.2-13.7% wet weight basis); as well as final weight, ranging from 25% to 32% (3.90-4.12 g), weekly growth ranging from 25% to 34% (0.59-0.63 g), and shrimp yield by 22-39% (1.72-1.96 kg m À3 ), as compared to control (12.1% wet weight basis, 3.12 g, 0.47 g, and 1.41 kg m À3 respectively). It can thus be concluded that cultivating Gracilaria birdiae in an IBS with L. vannamei can contribute to DIN and NO 3 -N removal, lower Vibrio density, increased crude protein in whole body shrimp, higher growth and yield parameters in shrimp culture.

“…Seaweeds contain bioactive substances such as polysaccharides, proteins, lipids, and polyphenols with a diversity of antibacterial, antiviral, and antifungal activity (Peso-Echarri et al, 2012). Cell walls of seaweeds contain a wide range of polysaccharides, such as β-(1→3)-glucans that are formed by neutral sugars and acids, and can act as elicitors when applied to plant tissues (Battacharyya et al, 2015).…”

Cell walls of seaweeds contain a wide number of organic and inorganic constituents, of which polysaccharides have important biological activity. Some researchers suggest that polysaccharides from seaweeds can behave as biotic elicitors in viticulture, triggering the synthesis of phenolic compounds in leaves and grape berries. The mechanism of action of seaweeds after a foliar application to grapevines is not fully understood but it is discussed in this review. An overview of the recent research focused on the effects of seaweeds foliar applications on grapevine productivity, on grape and wine quality is included as well as a short-term future perspective for the research in this field.

“…Other important compounds found in seaweed are β-glucan, carotenoids, tocopherols, polyphenols, polysaccharides -which act as antioxidants and promote bioactivity against virulent antibiotic resistance (Peso- Echarri et al, 2012;Kolanjinathan et al, 2014) -balanced minerals (sodium, potassium, calcium, iron, magnesium, zinc, nickel, copper, cobalt) and vitamins (A, E, C B1, and B2) (Tabarsa et al, 2012;Syad et al, 2013), which may improve shrimp production in integrated biofloc systems. It is important to remember that according to Tacon (1987), reduction in the shrimps' ability to absorb certain minerals and vitamins from the water may arise under intensive shrimp rearing.…”

A trial was conducted for 42 days to evaluate the effects of two commercial feeds with high and low crude protein content on the performance of white shrimp Litopenaeus vannamei cultivated in an integrated biofloc system with the seaweed Gracilaria birdiae. The experiment had a 2 × 2 factorial design (a biofloc monoculture or an integrated system with 32% (low) or 40% (high) crude protein content) with the following treatments: IS32 (an integrated system using low protein commercial feed); IS40 (an integrated system using high protein commercial feed); M32 (a monoculture system using low protein commercial feed); and M40 (a monoculture system using high protein commercial feed), all in triplicate. Shrimp individuals (0.23 ± 0.04 g) were stocked at a density of 500 shrimp/m 3 and no water exchange was carried out during the experimental period. No significant influence (p > 0.05) was found to be caused by the integrated system or the crude protein levels on water quality. However, a significant influence (p < 0.05) was found for final weight (3.21-4.12 g), weight gain (2.97-3.89 g), yield (1.39-1.96 kg/m 3 ) and feed conversion ratio (1.47-1.74). Growth was similar in IS32, M40 and IS40, indicating that crude protein levels can be reduced with no adverse effect on shrimp performance variables in integrated biofloc systems with G. birdiae.Additional keywords: growth; nutrition; seaweed; shrimp; water quality.
