The present work aimed to obtain a mathematical expression to calculate the amount of EDTA required to produce calcium-free and low-calcium water ([Ca2+] < 5 mg L-1). Initially, a pilot test was carried out to confirm the effectiveness of EDTA as a chelating agent of waterborne calcium and to evaluate its effect on water pH. Five application rates of Na-EDTA (25, 50, 75, 100 and 125 mg L-1) were tested. The concentration of calcium in water was determined initially (before the application of EDTA) and after one hour. Linear regression analysis was performed to find out the relationship between the desired calcium concentration in water and the required EDTA: initial calcium hardness ratio. The expression ŷ = -0.0911x + 3.3628 (R² = 0.933) was derived...

Current experiment was undertaken during 6 weeks with Nile tilapia, Oreochomis niloticus, fingerlings (1.28 ± 0.03 g) to assess the effects of moderate Na2CO3 liming on water quality and fish growth performance. Twenty-four 25 L-aquaria, with 15 fish per aquarium, were used, of which twelve aquaria were placed in the lab’s indoor room and twelve in the outdoor area. Two types of water (clear or green) and three different water-quality managements (none, HCl acidification and Na2CO3 liming) were simultaneously evaluated in a 3 x 2 factorial design. Total ammonia, calcium hardness, pH and total alkalinity in the green water aquaria were significantly higher than rates in the clear water aquaria. Slight liming acid water with Na2CO3 did not produce...

The objective of the present work was to determine the effects of the interaction between feeding rate and area for periphyton in rearing aquaria for Nile tilapia. Twenty 25 L polyethylene outdoor aquaria were used to hold experimental fish. Three tilapia fingerlings (2.56 ± 0.14 g) were stocked in each aquarium for five weeks (12 fish m-2). There were two different feeding rates (full and full minus 30%) and two submerged areas for periphyton development (59.4% and 96.5% of the aquarium surface area; n = 5). Final body weight, specific growth rate and yield in the 96.5%-area aquaria of fish submitted to 30% less feed were significantly higher than in the 96.5%-area aquaria submitted to full feeding rates. Fish growth in the restricted-feed aquaria was...

Can a small change in the tilapia’s on-going feeding strategy impair its growth? - doi: 10.4025/actascianimsci.v35i3.18290

Caldini, Nayara Nunes; Universidade Federal do Ceará; Pereira, Nayagra Vidal; Universidade Federal do Ceará; Rebouças, Vanessa Tomaz; Universidade Federal do Ceará; Sá, Marcelo Vinícius do Carmo e; UFC.

The aim of the present work was to answer the following question: can a small change in the tilapia’s on-going feeding strategy impair its growth? In the initial phase of the study, fish were evenly distributed and maintained for two weeks in four tanks. In tanks 1 and 2, the ration was given in three equal meals at 8, 12 and 16h or at 9, 13 and 17h, respectively. In tanks 3 and 4, there was only one daily meal at 9 or 10 o’clock, respectively. In the second 8-week phase, fish from tank 1 were distributed into two groups in ten 100-L tanks: the 8-12-16 group, in which fish were always fed at 8, 12 and 16h; and the 8-12-16/9-13-17 group, in which fish were fed at 8, 12 and 16h in the first four weeks and at 9, 13 and 17h in the last four weeks. Fish from...

This study determined whether high levels of total ammonia nitrogen (TAN) as NH4+ are harmful to the growth performance of Nile tilapia juveniles. Fingerlings (0.31 ± 0.04 g) were assigned to 30 polyethylene 100-L tanks in a roofed room for 12 rearing weeks. There were increasing levels of TAN by increased NH4Cl application rates (0.0; 0.25 and 0.50 g tank-1 week-1) at three conditions of water pH (acidic, 6.2 ± 0.5; neutral, 7.2 ± 0.8 and alkaline, 8.8 ± 0.3). The application of HCl to acidic tanks caused 100% of TAN to be converted into NH4+. The poorest growth performance results were observed for the alkaline tanks subjected to the highest application of NH4Cl. In acidic tanks, fish survival has dropped in those tanks under the highest application rate...

Expansion of aquaculture around the world has heavily impacted the environment. Because fertilizers are needed to raise fish, one of the main impacts is eutrophication, which lowers water quality and increases the frequency of algal blooms, mostly cyanobacteria. To evaluate whether the water quality in 30 fishponds in southeastern Brazilian met the requirements of Brazilian legislation, we analyzed biotic and abiotic water conditions. We expected that the high nutrient levels due to fertilization would cause low water quality. We also analyzed cyanotoxins in seston and fish muscle in some systems where cyanobacteria were dominant. The fishponds ranged from eutrophic and hypereutrophic with high phytoplankton biomass. Although cyanobacteria were dominant in...

The aim of the present study was to determine the effects of waterborne un-ionized ammonia (NH3) on the survival and growth of silver catfish (Rhamdia quelen). Juveniles were exposed to 0.10, 0.22, and 0.42mg L-1 NH3 at pH 8.2 for 45 days. After 15 days, a significant mortality rate (33%) was observed in the fish exposed to 0.42mg L-1 NH3. After 20 days, 23% and 43% mortality (both significant) was observed in fish exposed to 0.22 and 0.42mg L-1 NH3, respectively. A significant negative relationship between survival, length, daily weight gain, standard growth rate, and biomass of juveniles of silver catfish per tank with waterborne NH3 levels was found at the end of the experiment. The resulting survival and waterborne NH3 relationship indicated that, to...

The present research aimed to assess a lab-scale model to study periphyton-based systems for fish culture. Twenty-five liters plastic aquaria were stocked with three Nile tilapia, Oreochromis niloticus, juveniles (0.77±0.09g; 12 fish m-2) for 6 weeks in a 2x2 factorial design. Small plastic bottles were placed in some aquaria for periphyton development. Two feeding regimes were employed: "full-fed" (standard feeding rates were fully adopted) and "half-fed" (50% of standard feeding rates). Growth performance and limnological variables were observed in each aquarium. There werefive replicates per treatment. Fish have fed actively on periphyton, especially in the half-fed aquaria. The placement of periphyton bottles had no significant effects on the water...

ABSTRACT: The aim of this study was to determine the level of dietary crude protein (CP) (480, 400, 440, 520 and 560g kg-1) in rations for juvenile II fat snook (Centropomus parallelus) that best promotes protein absorption and lower excretion of nitrogenous products. Three experiments were conducted: the first assessed the protein retention rate; the second evaluated ammonia excretion; and the third determined the best digestibility coefficient. The estimated protein retention rate showed a positive quadratic response to dietary CP with maximum retention at the 510.20g kg-1 protein level, and increasing levels of protein resulted in a greater total ammonia excretion rate in water. The mean apparent protein digestibility coefficient values increased with...

ABSTRACT: The growth of cachama hybrids, cachamoto (Colossoma macropomum ♀ x Piaractus brachypomus ♂) and cachamay (P. brachypomus ♀ x C. macropomum ♂) was compared for 154 days to determine which showed the better productivity. The experiment was carried out in three earth ponds, each divided transversely with a plastic net, yielding six experimental units. Juveniles of cachamoto of 12.95±2.43g and 6.75±0.42cm and cachamay of 16.65±3.64g and 7.41±0.62cm were distributed in each sub-tank of 240m2 at a density of 0.5 fish m-2. Fish were fed twice daily except on days when their weight and length, and the physical and chemical parameters of the water were measured. The following productive variables were evaluated: growth in weight and length, daily weight...

The genetic monitoring of interspecific hybrids involves the application of methodologies able to provide an easy and indubitable genetic characterization of both parental and hybrid individuals. In the present work, cytogenetic techniques were used to identify a hybrid lineage of "Piaupara" in order to caracterize them in relation to the parental species, Leporinus macrocephalus (piauçu) and L. elongatus (piapara). The cytogenetic analysis revealed that L. macrocephalus presented 2n = 54 chromosomes and a nucleolar organizer regions (NOR) at the telomere of the long arm of the submetacentric chromosome pair 2. Analysis of constitutive heterochromatin (C-banding) revealed a conspicuous block at the pericentromeric region on the long arm of a submetacentric...
