This study investigated the use of a combined formula artificial feed and fresh marine algae Gracilaria sp in submerged cage culture system its effect on Haliotis squamata relative growth survival rates. The experiment was performed Lae-Lae Island, Makassar from May to October 2016. sample Abalone juvenile larvae were 1.5 cm size stocked at density 30 pcs/cage. x 15 7 equipped with 2-inch Paral...

Flow hindrance by salt-marsh vegetation is manifested in the structure of the tidal current; it has a significant impact on sediment transport and causes increased sediment accretion. The flow characteristics in 3 different vegetation types (Spartina maritima, Sp. anglica and Salicornia/Suaeda maritima) were measured on 3 salt-marshes in Portugal and England. Skimming flow develops above the Sp...

Climate change shuffles species ranges and creates novel interactions that may either buffer communities against climate change or exacerbate its effect. For instance, facilitation can become more prevalent in salt marshes under stressful conditions while competition is stronger in benign environments. Sea-level rise (SLR) is a consequence of climate change that affects the distribution of stre...

Seaweed cultivation is a high growth industry that is primarily targeted at human food and hydrocolloid markets. However, seaweed biomass also offers a feedstock for the production of nutrient-rich biochar for soil amelioration. We provide the first data of biochar yield and characteristics from intensively cultivated seaweeds (Saccharina, Undaria and Sargassum--brown seaweeds, and Gracilaria, ...

In the fish farming business, feed is highest operational cost, which reaches more than 60% of total production cost. Therefore, can be processed independently to reduce costs in aquaculture businesses. This study aimed determine survival rate and efficiency red tilapia (Oreochromis sp) fed artificial with addition seaweed (Gracilaria sp). research was carried out from June September 2021 at In...

Wastewater effluent from aquaculture ponds can affect aquatic ecosystems. To mitigate this problem, we designed 2 sets (southern and northern) of land-based and farm-scale sequential integrated multi-trophic aquaculture (IMTA) systems in order to reduce water pollution and to diversify and optimize aquaculture products in coastal southern Taiwan. In each system, the 1st pond cultivated milkfish...

BACKGROUND Seaweeds are taxonomically diverse benthic algae, which are rich in bioactive compounds. These compounds have a potential application in medicine. OBJECTIVES The aim of the study was to investigate the bioactive properties of three seaweed samples, Enteromorpha antenna, Enteromorpha linza and Gracilaria corticata were collected from the shoreline of Mahabalipuram, Tamilnadu.
