“…The high growth values achieved by the three strains in the first weeks of the experiment are in agreement with previous results with other Gracilaria species (Nelson et al 2001;Yang et al 2006;Samocha et al 2015). The mean RGR of the three strains of G. domingensis obtained for the whole period (2-4% day -1 ) was higher than those found in other Gracilaria species tested in shrimp ponds in Brazil (Marinho-Soriano et al 2002, 2009Oliveira et al 2012).…”

“…In such systems, the seaweed utilizes the animals' metabolic waste as fertilizer while absorbing CO 2 and releasing O 2 to the environment. The seaweed of economic potential cultivated in IMTA is doubly interesting, since it reduces environmental impact and provides biomass for the extraction of high-value compounds (Samocha et al 2015;Yu et al 2016;Barceló-Villalobos et al 2017). In addition, IMTA has the potential to contribute to a positive, sustainable image, and improved social acceptability (Barrington et al 2010).…”

Species of the genus Gracilaria are widely distributed around the world, and many are wild harvested and cultivated for phycocolloid production (agar) and human food. This study investigated the growth performance of three color strains of Gracilaria domingensis in an integrated organic system. The three chromatic variants (red, green, and brown) were cultured in a shrimp farm at two depths (surface and 20 cm). The highest relative growth rates were obtained in the first week of cultivation for all three strains studied. Although the growth rates and biomass were slightly higher at a depth of 20 cm, significant differences were not observed at different depths (p \ 0.05). The growth of the three strains varied significantly over time (p \ 0.001). The maximal growth values obtained were 11.25 ± 1.50% day -1 (red), 12.76 ± 3.96% day -1 (green), and 7.86 ± 1.75% day -1 (brown). The mean growth rates for the whole period were 4.63 ± 6.97, 3.38 ± 9.09, and 2.16 ± 6.61% day -1 for the red, green, and brown strains, respectively. The pigment content (chlorophyll a, phycocyanin, and phycoerythrin) of the three strains studied was higher at a depth of 20 cm, while the maximum electron transport rate (ETR max ) and photosynthetic efficiency were higher at the surface. The high growth rates obtained in this study demonstrate the great potential of this species for integrated organic farming. Moreover, the ecological success shown by the red strain suggests that this strain is the most suitable for integrated cultivation.

“…The initial experimental stocking densities were comparable to suggested commercial production systems (e.g. Akiyama & Anggawa 1999, Fitzsimmons 2001, Tian et al 2001, Hernández-Barraza et al 2012, da Silva 2013, Schveitzer et al 2013, Samocha et al 2015, Perschbacher & Stickney 2017, taking into consideration higher to super-intensive stocking den sities. The upper box was stocked with 12 red tilapia (2.6 kg or 240 fish m ).…”

“…The daytime/ nighttime cycle was fixed as 14 hours and 10 hours, respectively. After preservation, the dry mass of the seaweed, DM, was measured using the same method as in our previous work [11][12][13] . The "starved seaweed" was wiped with paper towels to remove solution on the surface, and kept in the desiccator with silica gel at room temperature for several days until the mass of dried seaweed became constant, to be determined as the initial dry mass of the seaweed.…”

“…Ammonia-N could be removed by biofiltration with microalga, effectively converting from ammonia-N to nitrate less toxic for the aquafarming fishery products [6][7][8][9] . The biofilter systems employing macroalga have reported that 70-95 % of ammonia-N in the effluent could be removed using Gracilaria chilensis in salmon aquaculture ponds 10,11 and some research activities were reported on the application of Ulva lactuca to the farming of Oreochromis spilurus to control the water quality in the aquaculture 12 . On the other hand, different types of treatment systems have been suggested, in which the separation of ammonia-N by some kinds of adsorbents should be carried out to control the water quality of the culture pond.…”

To control the water quality in the intensive shrimp mariculture pond by uptaking the total ammonia-nitrogen with sterile Ulva sp., the growth rate of sterile Ulva sp. was experimentally measured and the influence of the rate on the water quality control evaluated. The specific growth rate constant of the seaweed increased with the total ammonia-nitrogen concentration, photosynthetic photon flux density and operating temperature. Then the dynamics of ammonia-nitrogen in the modeled culture pond for the intensive shrimp farming in the tropical region were numerically simulated, in which the seaweed was used to uptake ammonia-nitrogen. The seaweed could uptake ammonia-nitrogen effectively during daytime mainly due to the high intensity of sun light, and the total ammonia-nitrogen concentration in the shrimp pond could be kept very low. The required seaweed density to control the total ammonia-nitrogen concentration less than the recommended maximum concentration of 1.0 ⋅ 10 -3 kg N m -3 was estimated to be reasonable.
