Mantle margin morphogenesis in Nodipecten nodosus (Mollusca: Bivalvia): new insights into the development and the roles of bivalve pallial folds [PDF]
BMC Developmental Biology, 2015 Background: Despite extensive knowledge on bivalve anatomy and development, the formation and differentiation of the mantle margin and its associated organs remain largely unclear. Bivalves from the family Pectinidae (scallops) are particularly promising

Carotenoid extraction from the gonad of the scallop Nodipecten nodosus (Linnaeus, 1758) (Bivalvia: Pectinidae) [PDF]
Brazilian Journal of Biology, 2009 In marine bivalve mollusks, unsaturated molecules called carotenoids are present in the natural diet and play an important role in different biological process, especially in reproduction. In order to gain more insights into these compounds in Nodipecten

The karyotype of Nodipecten nodosus (Bivalvia: Pectinidae)
Hydrobiologia, 2000Earlier karyotypical work on Nodipecten nodosus embryos indicated that this species has a diploid number of 38, with six pairs respectively of metacentric and submetacentric chromosomes and seven pairs of subtelocentric chromosomes, although there were some difficulties in obtaining complete metaphases.

We report the construction and characterization of a normalized cDNA library from the digestive gland of the marine bivalve Nodipecten nodosus, a commercially valuable tropical scallop. A total of 288 clones were sequenced, and 250 unique sequences were obtained. The cDNA library showed a small sequence redundancy (2.3%) and high numbers of recombinant

Cadmium bioaccumulation in Nodipecten nodosus reared on a marine farm in a tropical bay was measured in muscle tissue and the digestive glands in animals ranging from 6 to 16 months. No bioaccumulation tendencies regarding Cd concentration were observed in muscle tissue (below 1 μg g⁻¹), while in the digestive gland concentrations remained below 5 μg g⁻

Argopecten nucleus and Nodipecten nodosus are two commercially valuable scallop species found in the western Caribbean region. Field and laboratory experimentation was carried out to determine the feasibility of artificial induction of gonadal development in these species in order to have fully mature broodstock to provide gametes for massive culture ...

Tentacular organs comprise a variety of body projections that have specialized functions in several invertebrate phyla. In bivalve mollusks, tentacles of the mantle margin serve sensorial and secretory functions involved in predator detection and interactions with the surrounding environment.

Mollusc rearing is a relevant global socioeconomic activity. However, this activity has faced severe problems in the last years in southeast Brazil. The mariculture scallop production dropped from 51,2 tons in 2016 to 10,2 tons in 2022 in the Baia da Ilha Grande (BIG; Rio de Janeiro). However, the possible causes of this collapse are unknown.
