Abstract:

Abstract A multi-scale approach is essential to assess the factors that limit avian habitat use. Numerous studies have examined habitat use by the red-crowned crane, but integrated multi-scale habitat use information is lacking. We evaluated the effects of several habitat variables quantified across many spatial scales on crane use and abundance in two periods (2000 and 2009) at Yancheng National Nature Reserve, China. The natural wetlands decreased in area by 30,601 ha (-6.9%) from 2000 to 2009, predominantly as a result of conversion to aquaculture ponds and farmland, and the remaining was u

Abstract:

In the plain-lake area of south China, aquaculture and plantation of aquatic commercial crop are very common. In order to realize water quality improvement for aquaculture pond and reuse of the nutrients, it is essential to establish an integrated system that constitute aquaculture pond and plant purifying pond which are linked by necessary farmland works. In the study, the connection between fishpond and lotus pond was established mainly by water pipe and water suction pump. When lotus pond is used for purifying fishpond water, using water pump draw water from fishpond into lotus pond, then e

Abstract:

SUMMARYField irrigation is costly in arid regions, and over-fertilization of farmland can lead to high groundwater nitrate levels and significant environmental challenges. Integrative aquaculture and agriculture (IAA) systems allow the reuse of water and nutrients to offset production costs while promoting greater sustainability. The aim of this study was to test the effectiveness of an IAA system using treatments formed from one water source, groundwater (GRND) or fish pond effluent (EFF), and one chemical fertilizer regime, eliminated (ELIM) or historical (HIST).

Abstract:

The purppuse of research was to study the feasibility of fish culture technically and economically. Primary data was gathered by interview to fish farmer and secondary data was obtained from related references. Data analyzed were break even point and foof conversion ratio. Water source of pond was spring water and the pond depth was 0.50 – 1.75 m. Juveniles were obtained fron Tatelu Freshwater Aquaculture Board and other palces. Fish was fedr pellet for 3-4 months. Pond conctruction did not match the criteria . Fish farmer did not used capital from bank and farmers did not use book account in

Abstract:

Background. Water quality in the Marilao-Meycauayan-Obando river system (MMORS) of Bulacan, the Philippines, is of great concern due to the pollution load from local industries. The river system is currently used as a source of water for the aquaculture industry in Bulacan. Objectives. In order to address organic and heavy metal pollution, several remediation strategies were tested in aquaculture ponds along the river system. Strategies such as phytoremediation (vetiver grass pontoons), application of probiotics and zeolite (with filtration as pre-treatment) were utilized in ponds to decrease

Abstract:

Abstract In aquaculture systems, insufficient nutrients impede shrimp growth while excessive amounts of nutrient inputs lead to environmental degradation and unnecessary high investment. A study of in-out nutrient budgets in an intensive Litopenaeus vannamei farm was conducted in this work to measure the amount of nitrogen (N) and phosphorus (P) input and output from the system. The feed conversion ratio (FCR) was obtained to determine the level of nutrient input performance. Between September and December 2017, monthly water and sediment samples were taken within one crop cycle. Nutrient conc

Abstract:

The decline in vaname shrimp farming land in Lamongan Regency, East Java is influenced by the conversion of cultivation land into residential areas and industrial estate development so that it requires a breakthrough in aquaculture technology, one of which is by utilizing home garden for fish farming using tarpaulin ponds. This study aims to determine the feasibility of the cultivation of vaname shrimp in a circular pond with a recirculation system. The research method is an experimental method and qualitative descriptive in the cultivation of vaname shrimp in a circular pond with recirculatio

The study aimed to evaluate the combination between commercial feed and fermented tofu waste feeding for growth, survival rate and production of red Tilapia Oreochromis niloticus in pond. The study was conducted in Experimental Pond Installation of Research Institute for Coastal Aquaculture, Maros, South Sulawesi, using eight ponds with 2,500 m2 in size. Red Tilapia fingerlings (±8 cm in length) were reared for 112 days with 1 individu/m2 of stocking density. The feeding treatments were of 100% commercial feed (A), 75% commercial feed + 25% fermented tofu waste (B), 50% commercial feed + 50% f

AbstractCoastal reclamation seriously disturbs coastal wetland ecosystems, while its influences on soil microbial communities remain unclear. In this study, we examined the impacts of coastal reclamation on soil microbial communities based on phospholipid fatty acids (PLFA) analysis following the conversion of Phragmites australis wetlands to different land use types. Coastal reclamation enhanced total soil microbial biomass and various species (i.e., gram-positive bacterial, actinomycete, saturated straight-chain, and branched PLFA) following the conversion of P. australis wetland to aquacult

Abstract:

AbstractMangrove forests capture and store exceptionally large amounts of carbon and are increasingly recognised as an important ecosystem for carbon sequestration. Yet land-use change in the tropics threatens this ecosystem and its critical ‘blue carbon’ (carbon stored in marine and coastal habitats) stores. The expansion of shrimp aquaculture is among the major causes of mangrove loss globally. Here, we assess the impact of mangrove to shrimp pond conversion on ecosystem carbon stocks, and carbon losses and gains over time after ponds are abandoned. Our assessment is based on an intensive fi
