“…Water temperature in Aegean Sea rises over 15°C generally in March (Acarlı, 2005;Lök et al, 2007;Serdar et al, 2007), whereas these values are observed in Dardanelles only after April. Other environmental parameters, which are as important as the water temperature for oyster culturing, are the amount and quality of food in the region (Andersen and Nass, 1993;Rodriguez et al, 1997;Lodeiros et al, 1998;Laing, 2000;Tomaru et al, 2002;Baghurst and Mitchell, 2002;Mercado-Silva, 2005;Rebelo et al, 2005). Numerous studies display a strong relationship specifically between chlorophyll-a and CI.…”

This study was conducted in Dardanelles between October 2007 and August 2009 when condition index, meat yield, biochemical compositions and environmental parameters of seawater were investigated and the study area was found to have available conditions for cultivation. Investigation of the study area showed a positive correlation in particular among condition index, seasonal variation of temperature, protein, fat and chlorophyll-a; a negative correlation was seen between them and carbohydrate value. It was clear from the two years study that the most ideal period for oyster harvest is April and August especially when condition index was maximum followed by a winter with no oyster yield is available in terms of the related processes involving oyster cultivation.

“…The trays or nets provide protection from predation and permit water circulation, while excrement material is allowed to fall outside. Higher food supply associated with the upper euphotic zone has also been shown to promote growth in some suspended culture (MacDonald and Thompson, 1986;Lodeiros et al, 1998;Lodeiros et al, 2001). These methods also have disadvantages, especially in the upper water column where fouling and more variable abiotic conditions and wave energy may lead to increased mortality.…”

Evaluation of different shallow water culture methods for the scallop Nodipecten subnodosus using biologic and economic modeling

et al. 2006

The desire to develop sustainable small-scale aquaculture on the Baja California peninsula has focused attention toward the native scallop Nodipecten (Lyropecten) subnodosus, a species characterized by rapid growth, large size and high domestic market price. The cool upwelling waters around Bahía Magdalena seem to provide suitable conditions for N. subnodosus culture, yet cheaper, less technically demanding methods of culture are desired to add to the practicality of development for local resource users. Culturing in the shallow 'esteros' (reverse-estuaries) rather than in the central section of the bay may provide such an alternative. Between September 2002 and April 2003, three grow-out culture methods (suspended module, bottom and off-bottom culture) were compared at two different densities (40% and 60% coverage) in terms of scallop growth, mortality and associated costs, in order to create a predictive model of monetary returns. Scallops exhibited retarded growth and increased mortality during the warm, oxygen-poor water conditions of late summer (August-September), which coincided with increased reproductive activity (Gonad Index) and lowered energy reserves (Adductor Muscle Index). Growth performance was best during a period of lower temperature in late December 2002 to early January 2003. Of the six treatments, 40% density off-bottom culture provided the best grow-out conditions in terms of average growth and mortality (K year = 0.51, Z year = 0.29). However, a simulation of a 10-year culture operation accounting for the addition of a new batch of seed each year (100,000 ind.·year − 1 ) shows 60% density off-bottom culture (K year = 0.44, Z year = 0.37) to be the most profitable (net present value = US$28,631, internal rate of return = 27.0%). A 6-year period is predicted before the culture is profitable. The model proved valuable in comparing profitability between culture methods and is relevant as a tool for investment decisions in other culture operations.

Uso De Controle Biológico Para a Fauna Acompanhante No Cultivo Da Vieira Nodipecten Nodosus (Linnaeus, 1758)

RESUMOO cultivo de vieiras Nodipecten nodosus no litoral sul fluminense projeta a malacocultura do estado do Rio de Janeiro à terceira posição em volume de produção e segunda em valor gerado. É atividade importante tanto socioecomonicamente, gerando renda e emprego, quanto culturalmente ao ajudar a preservar a cultura tradicional caiçara. Influencia positivamente a biodiversidade ao fornecer substrato de fixação, abrigo e alimento para a biota marinha. No entanto a fixação de organismos da fauna acompanhante (fouling) nas estruturas de cultivo pode gerar desgaste e influenciar negativamente o desenvolvimento da vieira. O ouriço Echinometra lucunter, preferencialmente herbívoro, consome a comunidade de algas filamentosas essencial ao assentamento de larvas de organismos bentô-nicos. Dessa forma seu uso como controle biológico atua evitando o estabelecimento de larvas do fouling, mantendo as lanternas internamente limpas garantindo assim um melhor fluxo de água e alimento para as vieiras. Além disso, diversos organismos que compõe a fauna acompanhante também são filtradores e poten-
