Aquacultural Engineering Journal Impact Factor & Information

Publisher: Elsevier

Journal description

Aquacultural Engineering is concerned with the design and development of effective aquacultural systems for marine and freshwater facilities. The journal aims to apply the knowledge gained from basic research which potentially can be translated into commercial operations. Problems of scale-up and application of research data involve many parameters, both physical and biological, making it difficult to anticipate the interaction between the unit processes and the cultured animals. Aquacultural Engineering aims to develop this bioengineering interface for aquaculture and welcomes contributions in the following areas: - engineering and design of aquaculture facilities - engineering-based research studies - construction experience and techniques - in-service experience, commissioning, operation - materials selection and their uses - quantification of biological data and constraints Style of presentation is flexible, but those papers dealing with specific problems should attempt to define them clearly in terms of systems engineering, quantifying the constraints, proposing solutions, implementing and detailing the design, and finally evaluating the outcome.

    ABSTRACT: The measurement of total fish biomass is an essential practice in the aquaculture management. The method commonly used which involves removing a sub-sample of fish from a tank, weighing it and extrapolating the result to the whole tank, carries a large error, is intense labor and causes great stress. Here, we tested a laser scanning method to estimate the total fish biomass from the total fish volume of a sole population (Solea senegalensis) in a tank. The ratio FB/FLV of fish biomass (FB), weighing the 100% of soles, versus the fish layer volume (FLV) measured by the laser scanning, is calculated. Different fish size (small and large) and stocking densities (very low, low, medium and high) were tested. To test the method in the worst conditions, in very low stocking density, fish were 3.0g±1.1 (individual mean weight±SD); but in low, medium and high stocking density fish were 234.0g±84.6 (individual mean weight±SD). The fish layer volume included the fish biomass and the interstitial water present among them, which can be estimated from the ratio FB/FLV. In medium and high rearing densities with larger fish the ratio takes values very close to 1 (0.957±0.021 and 0.967±0.011) giving percentages of interstitial water lower than 5%. But in very low stocking density (0.4kg/m2) with smaller fish (3.0g±1.1), the ratio FB/FLV was much lower, giving a non-realistic percentage of interstitial water estimation. The low ratios obtained at very low stocking densities are due to the resolution of the image catching process, which is aggravated when working with small fish, since the error of a pixel from a digital image represents a larger percentage of error than with larger fish and higher stocking density. It should be noted that the coefficient of variation (CV) obtained was very low (in all cases lower than 7.2%) and decreased as the stocking density increased achieving the lowest value (1.1%) at high stocking density. The laser scanning has proven to be a useful tool to estimate the total fish layer volume of flatfish, and thus fish biomass, in an aquaculture tank with a usual grow-out stocking density for sole, reducing the labor involved and the stress commonly associated to manual sampling.

    ABSTRACT: Control of alkalinity, dissolved carbon dioxide (dCO2), and pH are critical in marine recirculating aquaculture systems (RAS) in order to maintain health and maximize growth. A small-scale prototype aragonite sand filled fluidized bed reactor was tested under varying conditions of alkalinity and dCO2 to develop and model the response of dCO2 across the reactor. A large-scale reactor was then incorporated into an operating marine recirculating aquaculture system to observe the reactor as the system moved toward equilibrium. The relationship between alkalinity dCO2, and pH across the reactor are described by multiple regression equations. The change in dCO2 across the small-scale reactor indicated a strong likelihood that an equilibrium alkalinity would be maintained by using a fluidized bed aragonite reactor. The large-scale reactor verified this observation and established equilibrium at an alkalinity of approximately 135mg/L as CaCO3, dCO2 of 9mg/L, and a pH of 7.0 within 4 days that was stable during a 14 day test period. The fluidized bed aragonite reactor has the potential to simplify alkalinity and pH control, and aid in dCO2 control in RAS design and operation. Aragonite sand, purchased in bulk, is less expensive than sodium bicarbonate and could reduce overall operating production costs.

    ABSTRACT: To improve the removal efficiency for dissolved wastes within CycloBio (CB) fluidized sand biofilters (FSBs) in recirculating aquaculture systems, we investigated their structural design and optimization using computational fluid dynamics (CFD) modeling tools, an orthogonal test method, and experimental verification. Results showed that the effects of structural parameters on bed expansion from large to small were: cone height, cone diameter and slot width. The best combination was: cone height 60mm, cone diameter 165mm, and slot width 1.0mm. The solid phase was well distributed not only in the radial direction, but also in the axial direction in the optimized CB FSB. The bed expansion (40%-120%) was increased about 13%. Energy savings were 21%-28% at the same bed expansion. When the optimized CB FSB was used to treat synthetic aquaculture wastewater, with three bed expansions and four levels of C/N, total ammonia nitrogen removal rate expressed per unit of expanded bed volume was high, from 629 to 881gm-3day-1. All results indicated that the structure of the optimized CB FSB was more reasonable and that the combination of CFD simulation and the orthogonal test method could be successfully applied to structural optimization.

    ABSTRACT: The effects of tank design on live feed consumption, growth and survival of sablefish (Anoplopoma fimbria) were examined from first-feeding larvae to weaned sub-juveniles. Larvae were stocked into wide circular 1920 L (WC, 152 cm diameter × 121 cm deep), tall circular 960 L (TC, 104 cm diameter × 152 cm deep), rectangular 150 L (RT; 78 cm × 49 cm × 54 cm deep) and conical 150 L (CO; 61 cm diameter (top), 20 cm (bottom) × 79 cm deep) tanks and reared under similar conditions and feed regimes. The experiment was conducted twice in close succession between March and August of 2012 and results from both trials were combined. At 20 days post first feeding (dpff), larvae from the WC and TC tanks were longer (p< 0.05) and consumed more Artemia than larvae from the CO tanks. The RT and CO treatments were terminated at 20 dpff due to poor survival. At 41 dpff, length, weight and SGR were not significantly different (p> 0.05) between the WC and TC treatments (WC-26.33 ± 0.71 mm, 145 ± 45 mg, 2.63 ± 0.19%; TC-26.45 ± 1.19 mm, 113 ± 40 mg, 2.76 ± 0.65%). However, survival was better in the WC treatments (21.1%) compared to the TC tanks (13.2%). Differences observed in larval survival between tank designs were most likely related to the overall volumes of the tanks as well as the relationship between depth and surface area that may be necessary to maintain optimal flow patterns. Because there is no recent published information on culturing sablefish from spawning through the sub-juvenile stage, this manuscript also includes an expanded methods and materials covering these topics.

    ABSTRACT: In this work, the practical application of a low-pressure hydrocyclone was examined for feed waste and fecal solid removal for common carp (27±3.1g, average±SD) and Nile tilapia (33±3.4g, average±SD) in a recirculating aquaculture system. The dimensions of the low-pressure hydrocyclone included an inflow diameter of 30mm, a cylinder length of 575mm, an overflow diameter of 60mm, an underflow diameter of 50mm, a cylinder diameter of 335mm and a cone angle of 68°. The different operating conditions tested were inflow rates of 400, 600, 800 and 1000mls-1, and underflow rates of 25%, 25%, 20% and 10% of the inflow rates, respectively. Feed waste totals of 4.1 to 4.8% and 3.6 to 4.0% of the feed intake were produced by the common carp and Nile tilapia, respectively. The maximum separation efficiency (Et) for the feed waste from the common carp was 71% at an inflow rate of 600mls-1 with an underflow rate of 25% of the inflow rate. The maximum separation efficiency for the feed waste from the tilapia was 59% at an inflow rate of 400mls-1 with an underflow rate of 25% of the inflow rate. The fecal solid production estimated from the digestibility was 37.9% and 35.7% of the feed intake for the common carp and Nile tilapia, respectively. The maximum separation efficiency for the feces from the common carp was 60% for an inflow rate of 600mls-1 and an underflow rate of 25% of the inflow rate. The maximum separation efficiency for the tilapia feces was 63% at an inflow of 400mls-1 with an underflow rate of 25% of the inflow rate. The low-pressure hydrocyclone can be adopted for prefiltration and/or post-filtration for the removal of various sized solids. Furthermore, the solids separated from the underflow can be easily removed for further processing.

    ABSTRACT: Aquaponics is a form of aquaculture that integrates hydroponics to raise edible plants and fish. There is growing interest in aquaponics because it can be practiced in non-traditional locations for agriculture such as inside warehouses and on marginal lands, and it can provide locally grown products without using synthetic pesticides, chemical fertilizers, or antibiotics. Yet questions remain about the ecological and economic sustainability of aquaponics. The objective of this study was to describe the operating conditions, inputs (energy, water, and fish feed) and outputs (edible crops and fish) and their relationship over two years for a small-scale raft aquaponics operation in Baltimore, Maryland, United States. The system had roughly 1% water loss per day and used an average of 35,950 L for replenishment per year. Predicted values suggest rainfall could completely replace the existing water needs. The average energy use was 19,526 kWh for propane and electricity per year at a cost of $2055 US dollars. The largest uses of electricity were in-tank water heaters. Comparing inputs to outputs, 104 L of water, 0.5 kg feed, and 56 kWh energy ($6 in energy costs) were needed to produce 1 kg of crops; and 292 L of water, 1.3 kg feed, and 159 kWh of energy ($12 in energy costs) were needed to produce a 1 kg increase in tilapia. Raising tilapia was a net loss, while raising crops was a net gain when comparing market prices to energy costs. Understanding energy, water, and feed use in aquaponic systems is essential to inform farm business plans. These data can serve as a point of comparison to other small-scale aquaponic systems, and inform future work on life cycle assessments of aquaponics.

    ABSTRACT: Studies have developed techniques for bullfrog feeding in which movement of the food stimulates food intake in the absence of housefly larvae. We analyze a completely randomized design with two treatments (vibrating tray and linear feeder) in triplicate. A total of 1800 bullfrog froglets (Lithobates catesbeianus) (7.60 ± 0.59 g) were divided in six pens of 12 m2 and density 25/m2. Three fattening pens contained linear cement feeders (3.0 × 0.50 m) with a V-shaped bottom that crossed the pen longitudinally at each side of the pool containing commercial diet (40% crude protein) with added 5% housefly larvae. In the other three pens, six vibrating feeders trays (80 × 34 cm) per pen were arranged linearly, three at each side of the pool with commercial ration without housefly larvae. The productive performance of frogs was assessed by weight gain, feed intake, feed conversion, specific growth rate and survival by 90 days. We observed that bullfrog froglets receiving food in a vibrating feeder tray present better productive performance (weight gain, feed conversion and specific growth rate) than animals fed ration and housefly larvae in a linear feeder. This response can be related to the greater visual stimulus of the food by frogs fed in vibrating feeder trays, in which food had greater movement.
