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: We assessed the hatchery performance of Litopenaeus vannamei between the mysis1 and postlarva5 stages, in a zero-exchange biofloc system. Two sources of organic carbon (molasses and dextrose) were evaluated and water quality, zootechnical parameters, microbiology, and water consumption during production were compared between carbon-supplemented and control groups. The mean values of the evaluated water quality parameters were appropriate for this production stage. Fertilization with molasses and dextrose efficiently controlled ammonia levels and ammonia did not reach the average concentrations that are considered toxic for the species (total ammonia < 1.3 mg L−1 and free ammonia<0.05 mg L−1). The number of heterotrophic bacteria in the water was greater in the molasses and dextrose groups than in the control group. However, there was no difference in Vibrionaceae count between groups. There was no difference between groups in survival (>85%), length (6.15 mm), dry weight (0.17 mg) of postlarvae5. Treatment with dextrose or molasses required approximately 12% of the water used by the control group. L. vannamei production rates and water quality were maintained without water exchange using a biofloc system supplemented with dextrose or molasses.

    ABSTRACT: Rainbow trout (100 g initial weight) were subjected to the combined effect of two culture densities (15 and 40 kg m-3, D15 and D40, respectively) and two dietary energy levels (22 and 27 MJ kg-1E22and E27, respectively) during a 75-days experimental period. At the end of the experiment, the growth rate as well as the metabolic and oxidative status of liver and muscle of fish were studied.

    ABSTRACT: The primary objective of this study was to develop an adaptive neural-based fuzzy inference system (ANFIS) for feeding decision-making in aquaculture. Silver perch (Bidyanus bidyanus) were raised under semi-intensive conditions in Taiwan. Because dissolved oxygen (DO) is a key factor that is helpful in detecting the appetite of fish at the initial period of the feeding activity and because the flocking and struggle behaviors of food-searching fish have a transient effect on the measurement of the DO, a simple water-reused rearing tank was prepared to measure the DO to develop a fuzzy logic controller (FLC). In the equivalent ANFIS of the FLC, two linguistic variables were used to describe the food-searching state of the fish population and establish a rule base composed of 15 rules. Furthermore, an alternate hybrid learning approach, which is a fuzzy logic technique based on artificial neural networks, was suggested to quickly model the linguistic variables and evaluate their relative contributions. The results indicated that a decision threshold of 0.17, which was inferred using the fuzzy logic approach, considerably benefits the feeding decision; the high rate of accurate judgments (with an accuracy of 97.89%), which was obtained by the ANFIS model, was close to the actual food searching behaviors of fish. Therefore, the application of the ANFIS model to the feeding decision system in an aquaculture rearing tank has considerable potential for success.

    ABSTRACT: Ozone was applied to seawater recirculating aquaculture systems (RAS) to measure the effects on water quality and biofilter efficiency. Three replicate experimental systems were used in this study. Each system consisted of four rectangular culture tanks, a sump, two settling chambers, a foam fractionator and a trickling biofilter. The control system (CS) was not ozonated, but Treatment 1 (T 20) and Treatment 2 (T 40) were ozonated with 20 and 40 g O3/kg feed day−1, respectively. Three hundred twenty black seabream (mean weight ± S.D. of 334.5 ± 1.9 g) were stocked into each system, and cultured for the entire 44-day study period. During this period, total residual oxidants (TRO), nitrogen compounds (Total-ammonia-N, TAN; nitrite-N, NO2-N and nitrate-N, NO3-N) were measured, and nitrification efficiencies of the trickling biofilters were calculated for each system.

    ABSTRACT: Particulate and dissolved nitrogen (N) waste components are removed in recirculating aquaculture systems (RAS) using different cleaning technologies, and to dimension and optimize their removal efficiency requires that the expected daily load of the different waste forms can be estimated. Using a laboratory, mass-balance approach, the current study examined the effects of commercially applied feeding levels on the loading of different N waste forms, including daily fluctuations in dissolved total nitrogen (TN), total ammonia nitrogen (TAN), urea-N, and non-characterized, dissolved N deriving from juvenile rainbow trout (Oncorhynchus mykiss). In addition, the study examined whether there was a removal of urea-N across a moving bed biofilter operated as end-of-pipe under commercial conditions. The laboratory, mass-balance study showed that there were no effects of feeding levels (1.3, 1.5 or 1.7% of the biomass per day ) on the excretion of dissolved N components, which constituted the majority of total N waste (>81.6% on average). The excretion of urea-N and non-characterized, dissolved N components constituted 12-13% and 9-11%, respectively of dissolved TN. The excretion of urea-N was largely constant and independent of the daily feeding practice, whereas that of non-characterized N appeared to reflect the daily feeding activity, following the trends in TN and TAN. The time limited feeding regime applied in the laboratory study resulted in a pulse in the excretion of TAN that a biofilter may be unable to fully level out, potentially resulting in unnoticed, critical water quality conditions in intensive RAS during certain times of the day. Particulate N waste constituted a minor fraction of total N waste (<18.4% on average), and the actual loading depended on the digestibility of dietary protein/nitrogen. Results from the commercially operated, nitrifying biofilter showed that urea-N was removed at a rate of 0.014 g N m2 day−1. Compared to the removal of TAN (0.208 g N m2 day−1), the moving bed biofilter was 1.07 times more active in removing dissolved N than immediately expected when only considering TAN.

    ABSTRACT: Cage culture of tilapia (Oreochromis niloticus) in large reservoirs is an emergent aquaculture practice in Brazil. Due to the availability of large amounts of suitable quality waters in hydroelectric dams, there is a large but still undetermined potential for cage aquaculture in the upper Paraná River basin. Sustainable aquaculture production should consider assessment of ecological carrying capacity for rational use of natural resources such as water bodies. The present survey estimates the ecological carrying capacity for tilapia cage culture in several sites on a large reservoir of “Ilha Solteira” upper Paraná River basin, Southeastern Brazil. Ecological carrying capacity was estimated based on the Dillon & Rigler (1975) mass balance model, considering limnological and farming field data to evaluate area-specific Phosphorus loads that can be assimilated in these environments. Using average farming data of feed composition, tilapia (Oreochromis niloticus) whole body composition and Feed Conversion Rate (FCR), the estimated emission of Phosphorus per ton of fish produced was 14.8 kg P ton−1. Modeling provided evidence for the importance of feed Phosphorus content and availability for determination of total allowable production, as well as the relevance of proper inputs of limnological field data. When field data was collected, only two sites (Ponte Pensa and Dourados) had aquaculture activities; as aquaculture is expanding, limnological information provided in the present study is a registry of conditions found before the massive aquaculture development. Production estimated to the reservoir as a whole (156,000 ton) is more than tenfold the pooled production (13,000 ton) of the fifteen selected sites; if production estimated to the reservoir as a whole cluster around a few best sites, than effects on water quality is expected to be even more drastic. The limit of 1% occupancy by aquaculture posed by Brazilian government is not an effective safeguard against excessive eutrophication, and detailed limnological studies are demanded for each inlet assigned for cage aquaculture. The impact of cage fish farming on the aquatic environment by the release of nutrients that affect water quality can not only bring about conflict with multiple users, but primarily exert a negative feedback effect in the cage operations themselves.

    ABSTRACT: A 21-day experiment was conducted to evaluate the application of biofloc technology in South American catfish larvae (Rhamdia quelen) grown at a density of 25 larvae L− 1. The effect of different concentrations of biofloc on the performance of larvae was also analyzed. Five treatments were tested; in three of them, catfish larvae were grown in enriched biofloc tanks arising from the intensive cultivation of tilapia (Oreochromis niloticus). In these treatments, three biofloc concentrations, expressed as total suspended solids (TSS) were tested: up to 200 mg L−1 (T200), between 400 and 600 mg L−1 (T400-600) and between 800 and 1,000 mg L −1 (T800-1000). In another treatment, called T-HET, cultivation began with clear water and the formation of biofloc and control of ammonia were performed by the daily addition of dextrose. In the control treatment, the larvae were cultured in clear water from a recirculation system. In all treatments, the larvae were fed with Artemia nauplii. The increase in TSS concentrations was not associated with the best growth of R. quelen, but the performance of the larvae was better in T200 and T-HET, compared to T400-600 and T800-1000. In T200 and T-HET, the biofloc presented a higher content of volatile suspended solids, which could be a nutritious source of food to the larvae. The lowest survival was recorded in the control treatment (10.2%) where larvae suffered from an Ichthyophthirius multifiliis infestation on the 15th day of the experiment. No infestation by I. multifiliis was observed in the biofloc treatments, where the mean survival was four times (46.9%) greater than the control. The results showed that R. quelen larvae can be grown in a biofloc system with TSS concentrations up to 1,000 mg L−1, but the best growth was registered in tanks with a higher percentage of volatile suspended solids (T200 and T-HET).
