Dynamic Energy Budget model suggests feeding constraints and physiological stress in black-lip pearl oysters, 5 years post mass-mortality event

A systematic prioritization approach for identifying suitable pearl oyster restocking zones following a mass mortality event in Takaroa Atoll, French Polynesia

“…This led to a quick decline of farming activities and a 24% decrease in the local population between 2012 and 2017 (census data from ISPF, 2017), owing to the lack of economic opportunities. Seven years after the mortality, as in 2021, the farming activity remains moribund, with in situ monitoring of farmed oysters suggesting slow growth (~0.04 mm.d -1 , less than half the expected growth) and relatively low reproductive effort (Monaco et al, 2021). Nevertheless, there are good signs of recovery as all oysters brought into the lagoon remain alive and grow, and it is expected that spat collection could take place again, provided that enough mature adult oysters, male and female, are able to spawn in the lagoon.…”
