Pinanın (Pinna nobilis, Linnaeus 1758) Büyüklüğe Bağlı Olarak İzmir Körfezi Ege Denizi Türkiye de Askı Kültür Sisteminde Yetiştiriciliği

Abstract

SummaryThe growth and survival of fan mussel (Pinna nobilis, Linnaeus) juveniles, from natural spatfall, were compared in two groups (large and small size) in Karantina Island Izmir, Turkey, between December 2004 and April 2006. Total live weight, shell length, width and thickness of fan mussel were measured monthly during the study period. Small (32 mm) and large (73 mm) size groups of fan mussel individuals reached 140.25±10.46 mm and 154.36±16.12 mm in length and 64.64±17.98 g and 99.74±30.53 g in live weight, respectively. Significant differences were found in increases of shell length and live weight. Environmental parameters such as chlorophyll-a, seawater temperature, salinity, particulate organic matter (POM) and particulate inorganic matter (PIM) were determined during each sampling period. Shell length increase was affected by chlorophyll-a and PIM. However, increases in shell length did not correlate with temperature and POM. Survival rates for small and large groups were 93% and 100%, respectively. Keywords

Sexual Maturation of Fan Mussel Pinna nobilis (Linnaeus, 1758) (Mollusca: Bivalvia) in Experimental Cages in the Mali Ston Bay (South Adriatic Sea)

“…In our conditions, we recorded a long spawning period, which can be indirectly confirmed by the relatively large oscillation in the dimensions of collected juveniles with collectors, where lengths range from 18.1 to 94.3 mm, with mean values of 35.2 ± 14.3 mm, similar to the size values in previous cultivation experiments [41]. According to some authors, the planktonic phase of larvae lasts 5-10 days [49] and we can conclude that acceptance on our collectors occurred over 5-6 months because such a growth rate from the minimum to maximum size of collected individuals was confirmed in previous post-larval growth experiments [11,25]. The length of spawning and multiple spawning events can characterize the species in a particular aquatorium.…”

“…Gametogenesis was also investigated, with findings indicating it is generally similar to other shellfish species [24]. The potential for suspension farming was explored in the eastern Mediterranean [25] alongside growth possibilities in commercial production conditions for oyster and mussel parks in the Adriatic [11].…”

Suspended culture of Pinna rudis enhances survival and allows the development of a seasonal growth model for Mediterranean Pinnids

“…Other environmental parameters, such as chlorophyll-a and DO showed an indirect correlation with growth in the present study. On the contrary, Acarli et al (2011) found a positive correlation between growth and chlorophyll-a and particulate inorganic matter, and no correlation with temperature in P. nobilis. The different methods used to measure chlorophyll-a in both studies, however, impede a deeper comparison of this variable between them.…”

“…Katsanevakis (2007) also notes low mortality in natural conditions in Lake Vougliameni, Greece (7 deaths in 160 individuals). Acarli et al (2011b) monitored the mortality of young P. nobilis in suspended PVC cages in Izmir Bay. A 7% mortality rate was recorded in a group of smaller individuals (shell lenght 32 mm).…”
