  • Modifications of macrobenthos assemblages on land–based fish farm phytotreatment basins in the Orbetello lagoon

    In the Orbetello lagoon basin there are some intensive land–based fish–farming facilities which contribute to cause a significant cyclic development of the opportunistic chorophycea Ulva laetevirens, and consequent serious decay events in spring and summer. To minimise the nutrients' impact, fish farming was supplied with phytotreatment system. The purpose of this study was to ...

  • A novel growth method for diatom algae in aquaculture waste water for natural food development and nutrient removal

    Diatom algae are known to play an important role as primary producers in many diverse ecosystems, including artificial aquaculture ponds where they also aid in maintaining water quality by consuming excess nutrients. But factors influencing their growth are still poorly understood. In the present study the effect of micronutrients, N:P ratio and silica concentration on benthic diatom Synedra ...

  • Ecological impacts of fluridone and copper sulphate in catfish aquaculture ponds

    Fluridone and copper sulphate are often used for controlling macrophytes and algae in aquaculture ponds. The present study examined the ecological effects of these chemicals on macrophyte, phytoplankton, and zooplankton biomass, plankton community structure, water quality parameters, and fish survival and yield in catfish culture ponds using a randomized complete block design. The estimated ...

  • Indonesia: Opportunity for shrimp aquaculture - Case Study

    Great opportunities exist in shrimp culture in Indonesia due to land availability and ideal climate. Already, this country is one of the largest producers in the world. Many farmers use AIRE-O2® aerators as their 'aerator of choice' because the 'performance is better than the paddlewheel and the AIRE-O2® aerators keep the bottom of the ponds cleaner,' said the manager at this farm. The P. ...

  • The treatment of (fish) ponds on an environmentally friendly manner with the usage of the LG Sonic case study

    Aquaculture, or aqua farming, is the cultivation of aquatic organisms, such as fish or shrimps, in a controlled environment. Where this happens in a closed water container, algae may occur that pollute the water and may damage the organisms grown. Many of the traditional methods to fight algae are either insufficient, cumbersome, environmentally unfriendly, or all of these. LG Sonic uses ...

  • Protective role of dietary N‐acetylcysteine on the oxidative stress induced by cylindrospermopsin in tilapia (Oreochromis niloticus)

    Cylindrospermopsin (CYN) is a toxin produced by various cyanobacteria species. Fish can be exposed to this cyanotoxin in their natural environments and in aquaculture ponds, and toxic effects can be derived. The present study investigated the effects of dietary N‐acetylcysteine (NAC) on the oxidative stress induced by pure CYN and CYN from lyophilized cells of Aphanizomenon ovalisporum in tilapia ...

  • Measurement of the amount of DissolvedOxygen

    Dissolved Oxygen (DO) is the term used for the measurement of the amount of oxygen dissolved in a unit volume of water. In water quality applications, such as aquaculture (including fish farming) and waste water treatment, the level of DO must be kept high. For aquaculture if the DO level falls too low the fish will suffocate. In sewage treatment, bacteria decompose the solids. If the DO ...

  • Simulations of nutrient emissions from a net cage aquaculture system in a Brazilian bay

    Hydrodynamics and transport simulations were conducted with the modeling software TELEMAC-2D on Icó-Mandantes bay, a branch of the Itaparica reservoir. The bay has a maximal operational water level amplitude of 5 m and is suffering from eutrophication and algae bloom. Therefore, we investigated low and high water level scenarios with two different high resolution meshes, with the purpose to ...

  • Development of new methods to assess invertebrate immunology and immunotoxicology in aquaculture: oysters and lobsters as examples

    In order to support healthy aquaculture, we developed assays to assess immune functions and their susceptibility to environmental conditions or toxicants. Flow cytometry allowed the rapid and quantitative analysis of oyster and lobster cell subpopulations and their functions (phagocytosis, peroxide production, natural killer cell-like activity and apoptosis). We demonstrated experimentally that ...
