“…Previous studies have focused on the integration of Ulva with finfish (Jim enez del R ıo et al 1996), abalone (Neori et al 1998(Neori et al , 2000 and prawns (Litopenaeus vannamei) (Copertino et al 2009;Cruz-Su arez et al 2010). Yamasaki et al (1997) showed that integration of kuruma prawn, Penaeus japonicus larvae and Ulva lactuca, resulted in higher survival and better growth of prawn larvae and lower bacterial density in seaweed treatments.…”

Growth, production and biofiltration rates of seaweed, Ulva lactuca were investigated at two stocking densities (3 kg and 6 kg m À2 ) and two effluent flow rates (5.4 and 10.8 m 3 day À1 ) to optimize an integrated mariculture system at Saudi Red Sea coast. effluents from fish-rearing tank, stocked with 200 kg fish (Oreochromis spilurus), fed to six seaweed tanks via sedimentation tank. Fish growth (weight gain 1.75 g fish day À1 ), net production (NP, 10.16 kg m À3 ) and survival (94.24%) were within acceptable limits. Ulva showed significantly higher (F = 62.62, d.f. 3, 35; P < 0.0001) specific growth rates at lower density compared with higher density and under high flow versus low flow (SGR = 5.78% vs. 2.55% at lower flow and 10.60% vs. 6.26% at higher flow). Biomass yield of Ulva at lowand high-stocking densities (111.11 and 83.2 g wet wt m À2 day À1 , respectively) at low flow and (267.44 and 244.19 g wet wt m À2 day À1 , respectively) at high flow show that high flow rate and lower density favoured growth. Removal rates of total ammonia nitrogen (TAN) (0.26-0.31 g m À2 day À1 ) and phosphate phosphorus (0.32-0.41 g m À2 day À1 ) by U. lactuca were not significantly different (F = 1.9, d.f. 3, 59; P = 0.1394 for TAN and F = 0.29, d.f. 3, 59; P = 0.8324 for phosphates) at both the flow rates and stocking densities. Results show that the effluent flow rate has significant impact over the performance of the seaweed than stocking density.

“…Although few reports evidenced the efficacy of algae-based products in shrimp health management (Furusawa et al, 1991;Yamasaki et al, 1997), the role of marine natural product in shrimp disease management has been realized recently (Selvin & Lipton, 2003, 2004Selvin et al 2004b;Huang et al, 2006;Manilal et al, 2009). It was found that marine secondary metabolites are promising resources for the development of eco-friendly management practices for shrimp diseases (Selvin & Lipton, 2003;Selvin et al, 2004Selvin et al, , 2004bManilal et al, 2009Manilal et al, , 2009a.…”

ABSTRACT. Secondary metabolites of the green algae, Ulva fasciata, were tested to determine the efficacy of controlling shrimp bacterial pathogens. Exploratory experiments indicated that an intermediate dose (1 g kg -1 of shrimp) of Ulva in the diet was highly effective at controlling bacterial pathogens of shrimp, as compared to lower (500 mg kg -1 ) and higher (1.5 g kg -1 ) doses. The pilot experiments evaluated the percent of relative protection afforded shrimps treated with Ulva diet and faced with various concentrations of bacterial pathogen. The survival of shrimps treated with Ulva diet was significant (P < 0.01). The present findings indicate that the green U. fasciata may be an excellent source for developing a potent medicated feed for shrimp disease management.

Metabolites secundario de algas verdes Ulva fasciata fue probado para determinar la eficacia de controlar el camarón pathogens bacterial. Las conclusiones de experimentos exploratorios indicaron que la dosis mediana (1 g kg -1 de camarón) de dieta Ulva era sumamente eficaz en el control de pathogens bacterial de camarón cuando comparado al más abajo (500 mg kg -1 ) y más alto (1,5 g kg) dosis. En los experimentos pilotos, la protección de pariente de por ciento de camarones trató con la dieta Ulva y desafió con varias concentraciones de bacterial patógeno fueron evaluados. La supervivencia de camarones trató con la dieta Ulva era significativo (P < 0,01). Basado en las conclusiones presentes, podría ser deducido que U. verde fasciata puede ser una fuente excelente para desarrollar la comida potente medicinal para la dirección de enfermedad de camarón.

Aquaculture in China accounts for nearly 70% of world aquaculture production. Aquaculture, including a wide variety of freshwater and marine fishes, shellfish, crustaceans, and aquatic plants, has become one of the most vital primary industries and a center of economic activity within the local and global economies. Along with the development of aquaculture, concerns come about such problems in the industry such as aquatic pollution, disease, genetic degradation of aquaculture species, decline of comparative profitability, lack of knowledge on market risks, and financial crises. Thus, there is a need to acquire further knowledge on this industry and provide sound suggestions for its sustainable development. This review aims to identify the current state of and challenges facing the aquaculture industry in China and to provide some suggestions for its sustainable development.
