Revisão: Uso de modelos matemáticos para avaliação da influência de variáveis ambientais sobre o desenvolvimento de ostras no Brasil

Abstract

The native oyster production is an economic activity that contributes to the preservation of estuaries, reducing pressure on wild stocks and promotes a sustainable exploitation. Knowledge of the environment variables, seasonal factors and the characterization of livestock development and reproductive cycle are essential for the technical and economic success. Based on these parameters, it is possible to develop mathematical models for understanding the relationship of these bivalves to the environment and rearing conditions, thus enabling guidance for decisions of producers, public administrators and researchers, in adapting their productive facilities to the ecosystem where they are inserted. This review aims to present a technical overview of native oyster's production, their relationship with environment factors and how mathematical modeling can be consolidated as an effective tool to integrate these data.

Growth Performance of the Mangrove Oyster Cultivated on the Amazon Coast

“…There are oyster crops throughout the Brazilian coast, however in the North and Northeast regions they are handmade and, in the South and Southeast, industrially [9]. In this scenario, the State of Santa Catarina stands out [2,10], responsible for 97.9% of Brazilian production in 2016 [11]. In the same year, oyster faming in the State of Pará presented a productivity of ~ 42 tons, (0.2% of the national production) [11].…”

“…World production from bivalve mollusk aquaculture plays an important role in human nutrition, and from the 1980s onwards it has grown rapidly until 2014 [1]. This growth in bivalve production is a result, for example, of the success of mussel farming and oyster farming, which appears as a viable alternative to mitigate fishery decline, reducing pressure on natural stocks [2] and becoming a source of income for coastal communities [3][4][5].…”

Análise biomorfométrica da ostra-do-mangue cultivada no litoral amazônico

“…Neste sentido, a ostreicultura apresenta estudos desde a década de 1970 [18], que possibilitaram seu rápido desenvolvimento. Dentre esses estudos, destacam-se a dinâmica reprodutiva (e.g., indução a desova, aspectos reprodutivos), do crescimento, além das influências ambientais no desenvolvimento da ostreicultura e eventuais predadores naturais [16,19,20,21]. Entretanto, observa-se através da revisão bibliográfica efetuada, que não existe dados que possibilite a estimação da produção da biomassa (em toneladas) de ostra comercializa, pois, as estatísticas se delimitam a produção em dúzias.…”
