Influence of grafter skill and season on cultured pearl shape, circles and rejects in Pinctada margaritifera aquaculture in Mangareva lagoon

Cultured pearls quality produced by the mollusc Pinctada margaritifera var. cumingi is determined by a panel of criteria, of which shape is one of the most relevant. Cultured pearls with round and semi-round (RS) shapes are the most valuable. Decreasing the proportion of other pearl shapes (OT: baroque, button, drop, oval), and especially the circled pearls (CL) and rejects (rebuts: RT), is an important challenge for the pearl industry. The present study examined the effect of grafter skill and season of graft on the variation in proportions of CL, RS, OT and RT cultured pearl shape categories in a mono-site culture (Mangareva island lagoon). Six large-scale grafting experiments, carried out in the same way as commercial grafting sessions, were made by...

The black-lipped pearl oyster, Pinctada margaritifera is the most important farmed mollusc species in French Polynesia. Donor oyster selection among wild P. margaritifera individuals, chosen according to their inner shell colour, makes it possible to obtain the broadest range of cultured pearl colours of any species. This study demonstrates the relative influence of using black [B] or red [R] outer shell phenotypes, combined with green [G] or yellow [Y] inner shell phenotypes, on pearl darkness level, colour categories and lustre. A large scale grafting experiment was designed and carried out over five grow-out locations, covering three archipelagos: Tuamotus, Society and Gambier. Results revealed that the [B + G] phenotypes may be used as donors to...

Fitness of early life stages in F1 interspecific hybrids between Dicentrarchus labrax and D. punctatus

Autores: Ky, Chin-long; Vergnet, Alain; Molinari, Nicolas; Fauvel, Christian; Bonhomme, Francois.
Inter- and intraspecific crossbreeding experiments were conducted to evaluate the aquaculture potential of hybrids in the genus Dicentrarchus, focusing on fertilisation and hatching success. The experimental design consisted of 24 controlled crosses in which individual and pooled fertilisations were made between wild D. labrax individuals (8 dams and 5 sires originating from West Mediterranean and Atlantic populations) and wild D. punctatus (6 sires). Three experiments were successively performed: (1) dams from the Mediterranean population, individually considered to have good egg quality, (2) dams from Mediterranean population, individually considered to have poor egg quality and (3) crossbreeding using pooled eggs from the Atlantic population. In each...

Is generalization of exhaled CO assessment in primary care helpful for early diagnosis of COPD?

Background: COPD is largely under-diagnosed and once diagnosed usually at a late stage. Early diagnosis is thoroughly recommended but most attempts failed as the disease is marginally known and screening marginally accepted. It is a rare cause of concern in primary care and spirometry is not very common. Exhaled carbon monoxide (eCO) is a 5-seconds easy-to-use device dedicated to monitor cigarette smoke consumption. We aimed to assess whether systematic eCO measurement in primary care is a useful tool to improve acceptance for early COPD diagnosis. Methods: This was a two-center randomized controlled trial enrolling 410 patients between March and May, 2013. Whatever was the reason of attendance to the clinic, all adults were proposed to measure eCO during...
