“…Penshells seeded in the bottom reached commercial size after 12 months; this represents 1.5 years from seed collection. The growth rate reported by the fishers is congruent with the rates recorded for other penshell species in Northwest Mexico (Arizpe‐Covarrubias, 1995; Chávez‐Villalba et al, 2022; Góngora‐Gómez et al, 2011). With the goal of recovering commercial beds through the constant sowing of seeds, Cooperative 1 has harvested only a few penshells of the sown animals (president of Cooperative 1, personal communication, November 2022).…”

The development of area‐based tools that combine fishing, aquaculture and repopulation practices is increasingly necessary and important to conserve ecosystems, promote sustainable use of marine resources and contribute to the well‐being of the people that rely on them. In the Gulf of California, Mexico, two small‐scale fishers' cooperatives were granted a Permit for Exploratory Aquaculture of bivalve species, and their members decided to set three zones within those concessions: (i) a zone for natural seed collection and repopulation, (ii) a no‐take zone and (iii) an area where fishing was allowed. This management arrangement, named by them as the Integral Management Zone (Zona de Manejo Integral), was conceived as an innovative alternative to the current policy tools available in the Mexican General Law for Sustainable Fisheries and Aquaculture. The natural collection of bivalve larvae in the artificial collectors was sufficient to allow the development of the repopulation project. Based on hydrodynamic models of larval dispersal, self‐recruitment was low, and the collection of seed depended on distant sources. The broader scale (regional) connectivity source–sink patterns should be considered in the design stages of the Integral Management Zones. The implementation of the Integral Management Zones can complement other conservation and fisheries management tools available in Mexican environmental and fisheries laws. The approach envisioned to implement this tool is participative, with a meaningful role of local fishers in the decisions concerning the use of these zones, with a supportive engagement of governmental and other stakeholders (e.g., academia and civil society organizations).

“…Most published studies on growth patterns in juveniles and adults of A. maura from field cultivation have used growth rate or a single mathematical model (generally Von Bertalanffy or exponential) as the criterion for analysis and comparison (Leal-Soto et al 2011, Góngora-Gómez et al 2016. Only Aragón-Noriega (2013) reported a multi-model approach for field cultivation from juveniles to adults of A. maura and selected the Gompertz model according to the lowest value of AIC.…”

“…Unlike most pen shells, A. maura is one of the most studied, focusing on broodstock conditioning (Rodríguez-Jaramillo et al 2001, Enríquez-Díaz et al 2003 and production of larvae and postlarvae in hatcheries at pilot and commercial levels (Robles-Mungaray et al 1996, Melguizo-Robles 2011, Escamilla-Montes et al 2017. It has served to carry out field culture trials that have shown the viability of achieving the production of fully-grown organisms (Miranda-Baeza 1995, Cardoza-Velasco 1998, Mellado-Moreno & Hoyos-Chairez 2008, Leal-Soto et al 2011, Góngora-Gómez et al 2016. Despite these encouraging results, no pen shell farm has maintained constant production because spat supply in the field is not guaranteed.…”

“…For instance, the production of Pacific oysters in various countries depends completely on hatchery-grown spat because of low natural or highly intermittent natural availability that does not guarantee the necessary supply (Nel et al 2014). In the case of A. maura, natural spat collection is erratic, intermittent, and seems to decrease yearly; thus, it cannot provide the required amounts to sustain commercial cultivation ventures (Góngora-Gómez et al 2016). Hence, it has been grown in controlled conditions, but the success rate is low, and most runs fail (Leal-Soto et al 2011), thus discouraging commercial hatcheries from producing this pen shell.…”

Hatchery spat of pen shells is difficult to obtain as production runs generally fail. We present a case of commercial pilot spat production of Atrina maura in the hatchery, describing each phase in detail and determining the growth of larvae and postlarvae using multi-model inference (MMI). Growth rates of larvae in D-veliger to umbo stage (D-larvae = 65 ± 5.1 μm height and 75 ± 5.1 μm length) increased from 4.33 μm d-1 up to 675.6 μm d-1 during postlarvae stage (spat = 10.9 ± 2.2 mm height and 28.1 ± 4.4 mm length). Survival presented a significant daily decrease from 22.5% (beginning) to a final absolute survival of 0.042%. Hence, 50,000 commercial spats were produced from 120 million D-larvae. MMI showed that the best-fitting model describing growth corresponds to a Gompertz model for shell length and an exponential model for shell height. Critical phases were transitioning from D-larvae to the umbo stage (>80% collapse of cultures) and high mortality during metamorphosis. Further studies are required to find solutions to these problems. The results of this study may contribute to improving the management of pen shell production in the hatchery, as the production protocol is different from those used for other bivalve species.

“…Bivalves feed on phytoplankton, dissolved organic matter, and bacteria [Sastry taken from Amezcua-Castro (2014) and Góngora-Gómez et al (2016)]. The seasonality of chl-a; POC showed continuous food availability in BM; in spring and sometimes, in autumn, nutrients supplied by upwellings cause algal blooms (ABs), composed mainly of diatoms and dinoflagellates (Gárate-Lizárraga and Siqueiros-Beltrones, 1998;Jiménez-Quiroz et al, 2019).…”

This study presents an overview of bivalve assemblages in Bahia Magdalena (BM, México) and the possible impact of environmental variability on these populations, constantly stressed by fishing. This lagoon is responsible for a high proportion of harvest of regional bivalves. First, we list the bivalve species reported in public biogeographic databases. Based on eight commercially exploited species, we described the composition of the bivalve assemblage and its biological characteristics, the history of fishery, and environmental variability in the marine area adjacent to the lagoon (1970–2019) and the habitat of bivalves (2002–2020). Sources of data were public databases and published literature. The enlisted species (n = 184) belong to six orders, and most are small and infaunal, but the structure of the assemblage is unknown. The fisheries began at different times and focused on the most valuable resources. Almost all harvest of bivalves had wide variations because of intensive fishing and a weak regulation frame. After 2015, the main resources were the Pacific wing-oyster (a new resource since 2017) and the geoduck clam due to the declining abundance of other resources (e.g., pen shells, Pacific calico scallop). There was a warming trend in the region since the 1970's, but the strongest El Niño-Southern Oscillation (ENSO) phases caused the most notable changes before 2013; after that year, a combination of large-scale phenomena increased the temperature significantly. The trend of chlorophyll-a abundance negatively correlated with temperature, but there was an almost constant supply of particulate organic matter in the interior of Bahia Magdalena (BM). After 2015, the quality of lagoon water gradually deteriorated, and in 2017 and 2019, harmful algal blooms developed, but the impact was not fully assessed. The challenges faced by the fishery are multiple (institutional weakness and regional warming); however, permanent monitoring programs of environmental conditions and critical biological variables should be implemented to design scenarios that allow fishery sustainability.
