“…This is in the case of blood clams Tegillarca granosa in China, particularly Guangxi and Shandong population is bigger than between the Shandong and Zhejiang population. Because Shandong population located in a temperate climate zone, where blood clams cease to grow in the winter season while the Guangxi population inhabits a subtropical area and can grow all year long [34].…”

Population genetics is not only a mere tool in determining the evolutionary aspect of an organism, nevertheless, also as a tool that implicates macrozoobenthic invertebrate population at the risk of over-exploitation, extinction, declining in number, and sustainable in status. These implications make the population genetically useful that unravel mysterious propound doubts beneath the vast seas and oceans. Macroozoobenthos species such as snails, clams, mussels, lobsters, crabs, shrimps, abalones, oysters, and corals are meroplankton that once in their life cycle they spent as plankton. They float in the water column and have transported hundreds to thousands of nautical miles depending on the water current before settling down and resume benthic mode of life. Their creeping and sedentary lifestyles are prone to easy collecting and gleaning, resulting in over-exploitation and over-harvesting in different regions. Thus, this review aims to consolidate several findings on the population genetic structure of macrozoobenthic species, which has implications for coastal resource management. Collectively, studies revealed that population genetic structures of macrozoobenthic invertebrates such as fine-scale, mesoscale and panmictic population that has genetic diversity, genetic differences, genetic homogeneity, and low genetic variability governed by the demographic barrier, salinity, water temperature, current, distance, and many others. Thus, population genetics is a vital tool in drafting, formulating, and conceptualizing conservation and protection measures of macrozoobenthic species with regards to coastal resource management.

“…No records were found of current genetic improvement programs in this species, nor any information on baseline data which would allow the development potential of such programs to be assessed. On the other hand, the natural population structure has been studied (Ni et al, 2012 ; Wang et al, 2013 ) and this is a pre-requirement for selecting brood-stock and forming families for an improvement program. Wang et al ( 2013 ) reported high genetic variability values, meaning that high diversity exists for brood-stock selection.…”

In 2012, world mollusk production in aquaculture reached a volume of 15,171,000 tons, representing 23% of total aquaculture production and positioning mollusks as the second most important category of aquaculture products (fishes are the first). Clams and oysters are the mollusk species with the highest production levels, followed in descending order by mussels, scallops, and abalones. In view of the increasing importance attached to genetic information on aquaculture, which can help with good maintenance and thus the sustainability of production, the present work offers a review of the state of knowledge on genetic and genomic information about mollusks produced in aquaculture. The analysis was applied to mollusks which are of importance for aquaculture, with emphasis on the 5 species with the highest production levels. According to FAO, these are: Japanese clam Ruditapes philippinarum; Pacific oyster Crassostrea gigas; Chilean mussel Mytilus chilensis; Blood clam Anadara granosa and Chinese clam Sinonovacula constricta. To date, the genomes of 5 species of mollusks have been sequenced, only one of which, Crassostrea gigas, coincides with the species with the greatest production in aquaculture. Another important species whose genome has been sequenced is Mytilus galloprovincialis, which is the second most important mussel in aquaculture production, after M. chilensis. Few genetic improvement programs have been reported in comparison with the number reported in fish species. The most commonly investigated species are oysters, with at least 5 genetic improvement programs reported, followed by abalones with 2 programs and mussels with one. The results of this work will establish the current situation with respect to the genetics of mollusks which are of importance for aquaculture production, in order to assist future decisions to ensure the sustainability of these resources.

Background Iron‐deficiency anemia is one severe micronutrient malnutrition and has captured worldwide attention. This study evaluated the in vitro iron absorption of two iron‐binding proteins (hemoglobin and ferritin) from Tegillarca granosa. In addition, the protein structure–iron absorption relationship and the regulatory effect of hepcidin on cellular iron absorption were explored. Results Our findings revealed that both hemoglobin and ferritin extracted from T. granosa contained abundant iron‐binding sites, as evidenced by stronger peaks in amide I and II regions compared with the two proteins from humans. Less β‐sheet (27.67%) structures were found in hemoglobin compared with ferritin (36.40%), probably contributing to its greater digestibility and more release of available iron. This was confirmed by the results of Caco‐2/HepG2 cell culture system that showed iron absorption of hemoglobin was 26.10–39.31% higher than that of ferritin with an iron content of 50–150 μmol L−1. This high iron absorption of hemoglobin (117.86–174.10 ng mg−1) could also be due to more hepcidin produced by HepG2 cells, thereby preventing ferroportin‐mediated iron efflux from Caco‐2 cells. In addition, the possible risk of oxidative stress was evaluated in cells post‐iron exposure. In comparison with ferrous sulfate, a common iron supplement, Caco‐2 cells treated with the iron‐binding proteins had a 9.50–25.73% lower level of intracellular reactive oxygen species, indicating the safety of hemoglobin and ferritin. Conclusion Collectively, the data of this research would be helpful for understanding the key features and potential of developing hemoglobin and ferritin from T. granosa as novel iron supplements. © 2022 Society of Chemical Industry.
