Intensive System

The super-intensive white shrimp system is more productive (t ha−1) than traditional systems. However, it implies greater investment in infrastructure and machinery, a continuous supply of electricity, and a specialized workforce. Therefore, the sustainability of a shrimp farm model operating in a super-intensive system in Nayarit (Mexico) was evaluated using financial analysis and life cycle assessment. The investment is important, but the fixed costs (16%) are much lower than variable costs (84%). The super-intensive farm is economically viable, with an overall profitability (29%) that is higher than that of other agri-food activities in Mexico. It is also an activity that generates a lot of employment, in relative terms, as well as economic movement in the area. The potential environmental impacts are higher than those registered in semi-intensive shrimp systems but slightly lower than those registered in intensive systems. The estimated global warming value per kg of shrimp is 5.08 kg CO2-eq, an intermediate value. Also, as the shrimp production is much higher than in traditional systems, it could have a great and positive impact on the maintenance and regeneration of the mangrove ecosystem.

The Difference

This research aimed to determine the stocking density that support the best growth and survival rate of carp cultivated in aquaponic systems, and to study the water quality of carp culture with different stocking densities in aquaponic systems. The study used 12 aquaria measuring 40x40x40 cm each (water volume of 50 liters). The experimental fish are carp (Cyprinus carpio) weighing in average of 3.5 g/individual.  The fish were cultivated with different stocking densities as treatment, including A = 4; B = 7; C = 10 and D = 13 individuals/aquarium.  The fish were fed with pellet at 5%/body weight/day with a feeding frequency of two times a day. The study was conducted for 4 weeks. Data consisting of daily growth, survival and water quality parameters (temperature, pH, dissolved oxygen, ammonia, nitrite and nitrate) were measured once a week. The data obtained were analyzed by ANOVA. The results of the study showed that the difference in stocking density had no significant effect on the growth and survival of carp.  Water quality was in a reasonable range to support the growth and survival of carp cultivated with aquaponic systems.Keywords: cultivation, carp, aquaponics, stocking density, growth

Penaeus Merguiensis

Estuarine of Kedungmalang has salinity variability and is assumed to bepolluted by cadmium (Cd) derived from human activities around Kedung region. In this study, bioaccumulation of Cd by white shrimp Penaeus merguienis in relation with salinity difference was determined. Sampling was conducted at four stations : estuary (15‰ and 25‰ of salinity) and husbandry area (15‰ and 25‰ of salinity). Data on in situ water quality parameters was obtained at each station. Absorption Atomic Spectrometer was used to measure Cd concentration. The water quality of parameters and the concentrations of Cd in the shrimp were compared with quality standards and weekly consumption limit of white shrimps is also suggested. The Cd concentrations on the white shrimp was found the highest concentration of 0.669 μg.g-1 . The limit comsumption of the white shrimp of Estuarine of Kedungmalang,suggested by the resut of this study, is about 523-1537 grams per week.

Aims: Water quality is one of them being an important role in terms of cultivation. Good water quality can support growth productivity in aquaculture. This is also of great concern when the rest of fish metabolism results that can contaminate fish contained in the maintenance media and if water is changed every day, water carrying toxins can pollute the area around the cultivation. One of the first steps to reduce the toxic content found in the maintenance media and the area around cultivation is to use aquaponic cultivation using biofloc. It is also expected to minimize the toxin content in maintenance media. This research aims to determine the comparison of the polyculture stocking density of sangkuriang catfish and nile tilapia which results in water quality that supports fish productivity. Study Design:  The research was conducted experimentally. Place and Duration of Study: This research was carried out for 40 days between March 2019 - April 2019 in the Ciparanje Laboratory of the Faculty of Fisheries and Marine Sciences, Universitas Padjadjaran. Methodology: The method used in this research is experimental using a completely randomized design (CRD), consisting of 5 treatments with 3 replications. The treatments to be given are dense stocking variations with the following treatments: A(75 catfish:75 tilapia), B(100 catfish:50 tilapia), C(125 catfish:25 tilapia), D(150 catfish), E(150 tilapia). Results: Water Quality Measured During The Study Namely, DO, Temperature, Ph, Nitrite, Nitrate And Ammonia Are Still In The Threshold For The Growth Of Test Animals During Maintenance. Conclusion: Based on the results of the research that has been done, it can be concluded that the quality of water in maintenance media using aquaponics biofloc gives good water quality values on maintenance media and is still within the threshold for the growth of catfish and tilapia.

Abstract The current development of aquaculture raises problems in the form of pollution of liquid waste generated during the production process. Aquaculture wastewater contains very high concentrations of inorganic nutrient. This study aims to determine the effectiveness of Sargassum polycystum density as a biofilter to reduce nitrate and phosphate in whiteleg shrimp pond. The study was conducted experimentally at indoor tank culture using a Completely Randomized Design (CRD) consisting of 3 density treatments with 3 replications, which were 1 gL−1, 2 gL−1, and 3 gL−1. The parameters observed were water quality such as nitrate, phosphate, temperature, salinity, pH, DO (Dissolved Oxygen), TSS (Total Suspended Solid), and TDS (Total Dissolved Solid); and also Saragassum’s growth. The results showed that the density of 3 gL−1 able to reduce nitrate 80% and phosphate 86,30%. The growth of S. polycystum for the three treatments decreased due to several factors, such as low nitrogen availability, environmental conditions, predators, and differences in stocking density. The average water quality measured during the study was temperature 27.84 °C; salinity 31.31 ppt; DO 4.72 mgL−1; pH 7.69; TDS 34.94 mgL−1; and TSS 4807.63 mgL−1. S. polycystum has the ability as biofilter for white shrimp culture because able to reduce nitrate and phosphate concentration. S. polycystum has potential benefits as alternative comodity candidate for polyculture and Integrated Multi Throphic Aquaculture (IMTA).
