In view of the high demand for brine shrimp larvae in marine shrimp larviculture, due to nutritional richness and practicality in management, several studies have focused efforts on techniques to preserve their biomass, since microcrustaceans are highly subject to decomposition. This study aimed to evaluate the use of canned Artemia salina nauplii in the larval cultivation of Litopenaeus vannamei. An experiment was carried out then a validation in commercial larviculture, Maris Laboratório - CE, both lasting 5 days. The first in 10 L buckets with 2 treatments (AN = fresh brine and AC = preserved brine) and 4 replicates. The validation in 25 m³ tanks, with the same treatments, but without repetitions. The larvae were accompanied by misis 1 to PL2 and evaluated by means of the following analyzes: bacteriological being performed at the beginning, middle and end of the experiment; water quality every day with the parameters of temperature, salinity, pH, ammonia and nitrite; finally, the zootechnical performance through the evaluation of larval quality, larval development index, survival, length and TBI. The data were submitted to ANOVA by the Tukey test for normally distributed data, the differences were reported when (P <0.05). The results were within the recommended standards for the species and there were no significant differences in the evaluations between treatments in any of the experiments. For future work, it is recommended to evaluate the economic viability of the product. Thus, it is possible to replace the nauplii of A. salina in natura by the one conserved in the larval cultivation of L. vannamei, since the test treatment did not alter the evaluated indexes.

Viabilidade econômica do empreendimento da Aquacultura Oliveira: carcinicultura de águas interiores na cidade de Feira Nova/PE
(2021-10-10) Oliveira, Émerson José da Silva; Silva, Luis Otávio Brito da; http://lattes.cnpq.br/3365265235618078; http://lattes.cnpq.br/7414873795164206
The production of marine shrimp (Litopenaeus vannamei) has been intensified far from the coastal regions, as they also present favorable conditions for its development. In addition to being far from regions that have a focus of disease incidence, the water quality has good ionic characteristics that allow for good zootechnical performance. In view of this, it is possible to perceive the degree of interest towards producers who start to increase shrimp farming within their production or migrate completely to the activity. With this, the objective of this work was to evaluate the technical and economic viability of the Aquacultura Oliveira enterprise regarding the production of marine shrimp in inland waters, in the city of Feira Nova, in the rural region of Pernambuco. The property has 1.25 hectares available, in which it operates with 07 semi-excavated nurseries totaling a productive area of 4,459 m2. The production system adopted will be by two-phase management and will have as a goal the annual production of 32 tons. At first, the total investment required for the implementation of the two-phase system and its entire operation is R$ 497,030.98. The commercialization of fresh shrimp will be responsible for the main sales method, which, added to the other types, will generate an estimated annual gross revenue of R$ 647,216.64. Through the sensitivity analysis, the following data were obtained: corrected net present value (NPV) of R$ 524,542.30; profitability index of 15.73%; profitability of 21.37%; discounted payback of 8.91 years; internal rate of return (IRR) 13%; average attractiveness rate (AMR) of 5%. In this way, it is possible to highlight the potential that the enterprise has to produce a protein with high nutritional value, in addition to presenting favorable characteristics for competitiveness in the market.
