Agricultural plants are extremely sensitive to climate change, because higher temperatures and changes in precipitation patterns increase the likelihood of diseases, which can lead to crop failures and irreversible damage to plants. Furthermore, the necessity of support for precision farming in cultivation, ...
The conditions for cultivation of microalgae Phaeodactylum tricornutum were studied with the objective of increasing algae lipid content for the production of biodiesel aiming at renewable energy generation. The variables investigated in the experiments were: salinity, carbon source (glycerol and glucose) ...
The recovery of biomass using flocculation is a procedure economically viable, however, it may cause damage to the cells and loss of the metabolic product of interest, such as lipids, according to the flocculant used and its concentration. In this work, different flocculants were evaluated for the flocculation ...
In general, having a good lifestyle and clean environment is the main goals in life. Hence, environmental monitoring plays a great role in human life. The problem of environmental pollution has become increasingly serious especially in water quality as well as air quality. Thus, this project aim on ...
Conference proceedings front matter may contain various advertisements, welcome messages, committee or program information, and other miscellaneous conference information. This may in some cases also include the cover art, table of contents, copyright statements, title-page or half title-pages, blank ...
Aquatic organisms can easily accumulate heavy metals via water and sediment. The aim of this study was to analyze heavy metals distributions of water, sediment and organisms of the thirteen aquaculture ponds at the southwest coast of Taiwan. To evaluate accumulate metals ability of organisms through ...
This paper describes the rapid prototyping of a low cost remotely controlled unmanned surface vessel (USV) intended for inspection of aqua farms. There is an increased focus on inspection of ocean-based aqua farms due to three major challenges: escaping fish, sea lice, and algae. Escaping fish may bring ...
The aim of this paper is to propose multi-purpose DOW utilization systems with enough capacity of ocean thermal energy conversion (OTEC), which can cover the total power of an isolated island as a renewable infrastructure, and to evaluate their economic feasibility and environmental impact focusing ...
The “Kumejima Model” is an integrated system of deep seawater use technologies designed for efficient use of seawater resources for the economic, social, and environmental benefit of island communities. It draws upon the existing industries and resources of Kumejima, Okinawa and applies the expanded ...
In recent years, the environmental relevance of coastal areas has increased. Therefore, development of environmentally friendly breakwaters is strongly expected. We selected three cases as the breakwater arrangements; one with no breakwater, one with conventional breakwater often seen near the mouths ...
Sensors are the essential devices for the agricultural applications. Sensors are mainly used in the agricultural field so as to enhance the productivity rate, enriched crop quality. The chances for intrusion of animals, strangers inside the field are very high especially during night times which leads ...
With the rapid increase in the construction of offshore wind farms and other coastal engineering projects, people begin to realize that anthropogenic underwater noise such as pile driving and underwater explosions can have an adverse impact on marine life. The Japanese eel (Anguilla japonica) is an ...
As one of the most alarming underwater noises today, pile driving noise is the only anthropogenic sound source other than explosives that has caused the death of fish , according to the available literature. The present study explored the effects of simulated pile driving noise on the movement behavior ...
In the present study, the potential of fly larvae meal as a protein source for incorporation in a diet used in culture animals of the genus Macrobrachium is evaluated. Two experimental feeds were formulated based on meal larvae, with differences in protein content (25 and 35%); they were provided to ...
Nile tilapia do not achieve the desired productivity in the semi-desert regions of Mexico, because of their temperature variations. Temperature needs to be regulated to obtain commercial weights in 6 months, as stated by governmental agencies. With the use of greenhouses it is not possible to maintain ...
Domoic acid (DA), a neurotoxic amino acid produced by diatoms, is the main cause of amnesic shellfish poisoning (ASP). In this work, we propose a very simple and fast analytical method to determine DA in mussel tissue. The method consists of two consecutive extractions and requires no purification steps, ...
We investigated the functional trait responses to 5 nm metallic silver nanoparticle (AgNPs) exposure in the Lessepsian-entry bivalve B. pharaonis. Respiration rate (oxygen consumption), heartbeat rate, and absorption efficiency were evaluated across an 8-day exposure period in mesocosmal conditions. ...
A number of ninety-six hair samples from Sicilian fishermen were examined for total mercury detection by an Inductively Coupled Plasma Mass Spectrometry (ICP-MS) method. The mercury levels obtained were compared with mercury levels of 96 hair samples from a control group, in order to assess potential ...
In the last few years, marine species have been investigated for the presence of natural products with anticancer activity. Using reversed phase chromatography, low molecular weight proteins were fractionated from the sea anemone Anemonia viridis. Four different fractions were evaluated for their cytotoxic ...
Inositols (myo-inositol and inositol hexakisphosphate) exert a wide range of critical activities in both physiological and pathological settings. Deregulated inositol metabolism has been recorded in a number of diseases, including cancer, where inositol modulates different critical pathways. Inositols ...
