“…At the age of 1.2 years, average shell heights at both locations were 70.4 ± 11.4 mm for suspension culture, compared with 60.9 ± 8.0 mm for bottom culture. Increased growth in suspension compared with bottom culture has previously been documented for a number of scallop species, including the Atlantic Lion's Paw scallop Nodipecten nodosus (Mendoza, Freites, Lodeiros, López & Himmelman ), the Pacific calico scallop A. ventricosus (Medina‐López ), the South East Pacific scallop Argopecten purpuratus (Wolff ), the north‐western Atlantic scallop Placopecten magellanicus (Emerson, Grant, Mallet & Carver ), the rock scallop Hinnites multirrugosus (Leighton ) and the Iceland scallop Chlamys islandica (Wallace & Reinsnes ). At EP, the bottom culture was situated at 8–10‐m depth, while suspended scallops were just below the surface.…”

This study focused on the comparison of growth and mortality of Lion's Paw scallops Nodipecten subnodosus from Gulf of California and Pacific populations and their reciprocal transplants, cultured in suspended module and bottom culture in Baja California Sur, Mexico. Environmental parameters were monitored to determine site‐specific differences and were correlated with scallops' population‐specific responses. Significant differences in growth were found between sites, populations and grow‐out methods. Growth performance of scallops originating from the Pacific population was lower and uniform between Pacific and Gulf culture sites, whereas Gulf scallops cultured at the Pacific site grew better. Growth and survival was higher in suspended than bottom culture, mainly due to depth‐associated differences in food and oxygen supply. Increasing temperatures and decreasing food and oxygen during summer months resulted in depressed growth and elevated mortality. At the Pacific site, this was partially compensated by considerably higher food availability. Gulf scallops resisted high diurnal temperature changes at San Buto significantly better than Pacific scallops. They also survived generally better than the Pacific population, independent of site and grow‐out method, indicating physiological adaptations to high temperatures and low food availability in their habitat. Consequently, the Gulf population appears to be more feasible for aquaculture operations in coastal lagoons with stressful conditions.

“…The foulsmelling odor in the bottom treatment, evident near the end of the culture period and likely due to excrement and pseudofeces accumulation, supports this. Mendoza et al (2003) also observed poor performance in bottom culture of Nodipecten nodosus cultured at starting densities of 30% coverage. Lower densities, as were used by Vélez et al (1995) for the grow-out of Euvola ziczac (final density ∼ 25%), may allow for better performance.…”

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

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.

“…O padrão de crescimento observado no presente trabalho foi muito semelhante ao registrado por outros autores para Nodipecten nodosus, como Mendoza et al (2003) e Marques et al (2004). O mesmo padrão também foi descrito para outros pectinídeos como Euvola ziczac (Linnaeus, 1758) por Freites et al (1993) e Argopecten nucleus (Born 1778) por Lodeiros et al (1993).…”

Mendoza et al (2003) estudando diferentes estruturas de cultivo suspensas para N. nodosus encontraram diferenças não significativas de crescimento entre "cones", 62,7 ± 2,20mm e "sacos" 63,3 ± 2,40mm, mas comparando-se as lanternas comuns (58,8 ± 0,44mm) e uma estrutura de fundo do tipo "curral" (56,1 ± 1,80mm), a diferença foi significativa. De acordo com esses resultados, ficou demonstrado que N. nodosus apresenta melhores taxas de crescimento em estruturas suspensas comparadas à estrutura de fundo.…”

ResumoProjeções estatísticas indicam que a aquicultura representará 40% da produção mundial de pescado na próxima década. A vieira Nodipecten nodosus apresenta alto valor comercial e boa potencialidade de cultivo, todavia existem poucos estudos sobre o cultivo dessa espécie no Brasil. O objetivo deste trabalho foi avaliar a influência de quatro estruturas de cultivo no crescimento e sobrevivência de vieiras cultivadas, além da facilidade de manejo (limpeza do "fouling" nas estruturas e nas vieiras). Os resultados mostraram que o crescimento foi significativamente maior na estrutura bo-net, com 57,6mm após 301 dias de cultivo, em relação às vieiras cultivadas nas outras estruturas outras estruturas. As sobrevivências registradas foram de 97,0% para a estrutura bo-net, 95,6% para as estruturas lanter-net e lanterna comum, e de 69,2% para a estrutura pearl-net. Ocorreram diferenças significativas na quantidade (peso úmido) de "fouling" incrustado nas diferentes estruturas, sendo a maior quantidade observada nas estruturas bo-net e lanter-net, porém essas diferenças não foram registradas para o peso seco. A estrutura lanter-net proporcionou incrustação de "fouling" significativamente maior nas vieiras. Conclui-se que as estruturas alternativas bo-net e lanter-net podem ser utilizadas, pois proporcionaram melhores valores de crescimento e sobrevivência das vieiras em cultivo. structures (three traditional and two alternative) regarding growth, survival and simplicity of cleaning off the fouling. Growth was significantly better in the alternative bo-net structure, with 57.6mm after 301 days. Survival was 97.0% in the bo-net structure, 95.6% in the lanter-net and common lantern structures, and 69.2% in the pearl-net structure. There were also significant differences among the fresh weights of fouling attached to the different structures, the highest values being observed in the bo-net and lanter-net structures. Significant differences were not registered among the fouling dry weights. The fresh weights of fouling attached to the shells presented significant differences, with the highest values registered in scallops cultivated in the lanter-net structure. Alternative structures (bo-net and lanter-net) can be employed, because they resulted in better growth and survival of the cultivated scallops.
