“…After 47 days, the scallops were transferred to tanks with a continuous upwelling flow of 5000 L day −1 using the same microalgae species for feeding. In October 2007, the animals reached the harvest size of 5–7 mm shell height (Maeda‐Martínez et al 1997). At the time, the spat was divided into two groups one of which was returned to the field, whereas the other group was kept for laboratory treatments (temperature and predation).…”

“…Subsequently, animals were kept without bags in the trays. Initial stocking density was set at 500 animals tray −1 (equivalent to 1700 animals m −2 ) for optimal growth (Maeda‐Martínez et al 1997) and adjusted to 150, 90 and 60 animals tray −1 (495, 297 and 198 animals m −2 ) after 187, 337 and 480 days (February, July and December 2008) in order to keep densities optimal for growth.…”

“…Bivalves offer a rich diversity of lifestyles and adaptations to environmental conditions and are ideal model organisms to study the influence of intrinsic and extrinsic variables on life‐history parameters such as growth, reproduction, fitness and senescence (Abele, Brey & Philipp 2009; Philipp & Abele 2010). The short lifespan of 2–3 years (Peña 2001) and the long‐standing use of the Catarina scallop ( Argopecten ventricosus) in aquaculture (Felix‐Pico 1993; Maeda‐Martínez, Reynoso‐Granados, Monsalvo‐Spencer, Sicard‐González, Mazón‐Suástegui, Hernandez, Segovia & Morales 1997; Sicard‐González, Maeda‐Martínez, Reynoso‐Granados, Ormart‐Castro, & Carvalho 1999; Steller & Cáceres‐Martínez 2009) render this species an ideal model to investigate the influence of environmental factors on life‐history parameters in laboratory experiments covering the species lifespan.…”

Environmental factors are known to modify the life history of marine ectotherms. In a 16-month laboratory experiment, we investigated the in£uence of temperature and presence of predators on life-history parameters including shell growth, survival and the energy investment in reproduction and body mass of the short-lived (2^3 years) scallop Argopecten ventricosus. In parallel, A. ventricosus was maintained in the ¢eld at the Paci¢c coast of Baja California, Me¤ xico, to compare growth, survival and reproductive effort under natural conditions. For the laboratory treatments, scallops were reared at simulated ¢eld temperatures (SFT), 5 1C above SFT and in the presence of predators. Elevated water temperatures caused higher growth and gonad production, although at the cost of increased mortality. Presence of predators induced energy allocation to muscle rather than gonad growth, deferred spawning and extended survival. Field scallops exhibited higher growth, higher reproductive investment and were able to reproduce twice, whereas all laboratory scallops died after the ¢rst spawning. The natural variability of environmental parameters such as food and temperature may thus support optimal growth in the ¢eld, and when animals are protected from predators, reproduction in the second year of life.

“…The density of the individuals within culture nets is one of the major factors affecting the growth and/or the survival of scallops cultured in the sea. Excessively high densities are deleterious to both their growth and survival (Hardy 1991; Freites, Vera, Lodeiros & Vélez 1995; Maeda‐Martínez, Reynoso‐Granados, Monsalvo‐Spencer, Sicard, Mazón‐Suástegui, Hernández, Segovia & Morales 1997; Román, Campos, Acosta & Cano 1999; Acosta, Freites & Lodeiros 2000; Maguire & Burnell 2001; Rupp 2007). But the use of low densities is not an economically viable option in commercial scallop farming (Hardy 1991).…”

Juveniles of the Caribbean scallops Argopecten nucleus and Nodipecten nodosus were suspended in pearl nets at densities of 25%,30% and 50% coverage of the bottom of the net (BC) during days. Additionally, adults of A. nucleus (435 mm) were placed in lantern nets at densities of 40%, 50% and 65% BC during days. Stocking density a¡ected the growth of animals, with higher growth rates obtained at the lower densities. Although the survival of the two scallops was not in£uenced at the densities studied, the 15-day net changes, and culture in water of o28 1C produced better survival of A. nucleus and N. nodosus respectively. Predators of the families Cymatiidae, Grapsidae, Portunidae, Majidae and Xanthidae were found in the culture nets of juvenile A. nucleus, but during the adult phase they were absent. Predators exhibited a dense-independent behaviour in relation to scallops. There was not any association between predator frequency and survival of A. nucleus.

“…A primary fisheries species is the Pacific calico or catarina scallop Argopecten ventricosus = circularis (Sowerby II, 1842), a motile, soft bottom species that reaches market size within a year. Extreme population declines due to multiple factors have resulted in efforts in Mexico to increase natural populations through aquaculture and enhanced field recruitment (Ruiz-Martinez & Cáceras-Martínez 1991, Felix-Pico et al 1997, Maeda-Martinez et al 1997). Similar population declines in Panamanian fisheries of the same species have been attributed to a lack of suitable habitat for early life stages, predation and changes in oceanographic conditions (Medina et al 2007).…”

) on fragmented rhodoliths. The strong cueing to live coralline surfaces may have resulted from live coralline algal surfaces or surface biofilms. Growth, presented as post-settlement size, was significantly greater in scallops that settled onto whole vs. fragmented rhodolith substrates for both live (246.6 ± 1.9 vs. 238.9 ± 4.4 µm) and dead (244.2 ± 2.8 vs. 234.7 ± 5.6 µm) coralline surfaces. The structural and coralline cues provided by live, intact rhodoliths and their large-grained sediments contribute to the importance of rhodolith beds as nursery habitats by increasing both scallop settlement and postsettlement growth. Protection of living rhodolith habitats can enhance scallop and other invertebrate populations as well as the sustainability of scallop fisheries by enhancing early life stages.KEY WORDS: Argopecten ventricosus · Coralline · Rhodolith · Scallop · Larval settlement cues · Lithophyllum margaritae · Maerl · Bahía Concepción Resale or republication not permitted without written consent of the publisherMar Ecol Prog Ser 396: [49][50][51][52][53][54][55][56][57][58][59][60] 2009 nell 1985, Raimondi 1990), and thereby strongly influence population and community-level processes (Rodriguez et al. 1993, Connolly & Roughgarden 1999. While hydrodynamic processes are known to strongly influence the delivery of larvae to suitable substrates (Butman et al. 1988, Abelson & Denny 1997, behavior in response to cues is also important in determining settlement patterns (Crisp 1974, Hadfield 1986, Raimondi & Morse 2000.Settlement cues, often required for metamorphosis of marine invertebrate larvae (Morse & Morse 1984, Pearce & Scheibling 1990, are thought to be indicative of environmental features that enhance survivorship (e.g. habitat, refuge, food or conspecifics). Physical cues include hydrodynamics (Crisp 1955), light (Crisp & Ritz 1973), depth (Knight-Jones & Morgan 1966), surface structural complexity (Harvey et al. 1993, disturbance events (Woodin et al. 1995) and surface chemistry (Hay 1996, Steinberg & de Nys 2002. Biological cues include presence of conspecifics (Keough 1998) and bacterial or bioorganic films (Maki et al. 1989, Keough & Raimondi 1995, Huggett et al. 2006). In addition, physical and biological cues can act synergistically (Crisp & Meadows 1963, Gee 1965, Le Tourneux & Bourget 1988. Few studies have been conducted in the field to understand in situ larval responses (Keough & Raimondi 1995) and how the distribution or magnitude of various cues might influence larval settlement (Underwood & Keough 2000).Complex seaweed surfaces, such as those found in coralline algae, provide combinations of physical and biological cues that can influence settlement in a range of invertebrates (Walters et al. 1996, Steinberg & de Nys 2002. Species of geniculate and non-geniculate (crustose) forms of coralline red algae occur in most coastal environments (Bosence 1983). A variety of invertebrate larvae are induced to settle on coralline algae by the physical features of the complex surfaces found on att...
