“…Like in other bivalves (GarciaDominguez et al 1998;Gribben et al 2004;Peharda et al 2006), the biggest oocytes in the horse-bearded mussel are found in ripe and partially spawned individuals. However, compared to other mytilids, oocytes of M. barbatus have a smaller maximum mean diameter (Honkoop and van der Meer 1998;Maloy et al 2003).…”

“…Such variability in the timing of spawning could occur also in M. barbatus, however, nothing is known on the reproductive behavior of other horse-bearded mussel populations in the Atlantic and the Mediterranean. Differences in the reproductive pattern within the same species were observed in other bivalves as well (Rodhouse et al 1984;Peharda et al 2006), and are suggested to be a constructive characteristic for the implementation of a profitable aquaculture, as in this way their broodstocks may be available over a broader time-scale (Gribben et al 2004).…”

“…The secondary peak of oocyte diameter shown in February however, consisted of a smaller number of spawned females with athretic folliculi in the process of reabsorption. The condition index is regarded as the most sensitive to changes in the reproductive development, and usually correlates well with the mean gonad index (Ojea et al 2004;Peharda et al 2006). Their determination was even suggested as a quick method to assess broodstock reproductive state (Gribben et al 2004).…”

The horse-bearded mussel Modiolus barbatus (Linneus, 1758) is an important edible bivalve in the Adriatic Sea; its population is especially large in the Mali Ston Bay area, where the species is present at depths up to 8 m. In order to assess the sustainable exploitation rate for this species, as well as to estimate its potential capacity for a sustainable aquaculture production, we determined the species' reproductive cycle along with its nutrient storage strategy, employing histological and biochemical methods. The population shows significantly more females than males, and no hermaphrodites. The smallest adult individual, an active male, was 16.0 mm in length, suggesting that sexual maturation starts around this length. While the period between January and February is characterized by sexual repose, early and late stages of gametogenesis were found between March and May, and spawning peaked from June till August. The increase of oocyte diameter followed the same trend. A significant positive correlation was observed between gonad index and temperature, and a negative correlation between gonad index and salinity. Oscillations of stored nutrients were tightly coupled with the gametogenic cycle.

“…This work is a part of intensive experimental investigations carried out from 2001 to 2004, mostly in the area of Mali Ston Bay, by a team of scientists from the Institute of Oceanography and Fisheries, Split-Laboratories Dubrovnik. The aim of the study was to collect data necessary for assessing the aquaculture potential of the bay and potentially initiating commercial production of Noah's Ark shell A. noae in the eastern part of the Adriatic Sea (Peharda et al, 2002(Peharda et al, , 2003(Peharda et al, , 2006. The reproductive cycle of this species was described by Peharda et al (2006) but no data are available on its biochemical composition and nutritional value.…”

Biochemical and fatty acid composition of Arca noae (Bivalvia: Arcidae) from the Mali Ston Bay, Adriatic Sea

Biochemical and fatty acid composition of the bivalve Arca noae were investigated in the Mali Ston Bay in relation to environmental conditions. Sampling was carried out monthly, from December 2001 to November 2002. Wet shellfish meat consists on average of 77.61% water and 22.39% dry matter, while dry shellfish meat consists on average of 89.04% organic and 10.96% inorganic matter. PCA analysis identified temperature, nitrate, silicate, MICRO, Chl a and salinity as the most important environmental factors influencing biochemical composition of A. noae. An increase of dry weight content of A. noae was observed during the spring when both the sea temperature and food supply increased rapidly. Contents of protein (54.39-62.06% of dry weight), carbohydrate (4.13-8.07% of dry weight) and lipid (3.46-8.58% of dry weight) varied significantly during the year. Protein and lipid level reached the maximum value in June. The fatty acid profiles of total lipids extracted from A. noae showed high level of unsaturation (UNS/SAT 1.9-3.4). Total polyunsaturated fatty acids (PUFA) represented the majority of total fatty acids (40.3-59.9% of total fatty acids) and the most abundant were eicosapentaenoic (20:5n-3) and docosahexaenoic (22:6n-3) acid. n-3/n-6 PUFA ratio value varied between 2.1 and 5.0 and was the highest during the spring (April to June). Due to their low lipid and high percentages of healthy polyunsaturated fatty acids A. noae can be evaluated as a quality seafood product. The most suitable period of the year for its consumption is in the spring when it reaches its highest nutritional values.

1. Biogenic reefs formed by bivalves are biodiversity hot spots that provide important ecosystem services, but are globally endangered. In Strangford Lough (Northern Ireland) the use of mobile fishing gear (MFG) has caused extensive damage to reefs formed by the horse mussel (Modiolus modiolus L.), leading to declines in their extent and condition.2. Captive breeding and translocation have been proposed as potential restorative strategies for the remaining reefs, and thus the reproductive biology of M. modiolus as the keystone species needs to be described prior to attempting large-scale ecological restoration.3. Physiological condition and gametogenesis were studied in two sympatric M. modiolus subpopulations using direct gonad assessment methods. The size-and age-frequency structure of the whole metapopulation were described to establish present or past recruitment events. Although gonad condition remained high in eachyear for the two subpopulations studied, significant losses were recorded in one subpopulation. These observations are consistent with autumn and winter spawning, but were not recorded in reefs thought to be more damaged by MFG. 5. Length-and age-frequency histograms showed a distinct bimodal distribution in all remnant M. modiolus subpopulations, which were dominated by mussels over 50 years old. Little or no successful recruitment has occurred in some subpopulations, where low reproductive output caused by declines in broodstock numbers might be preventing natural recovery. 6. A combined approach of strict protection of the remaining larval sources and active restoration through stock supplementation is recommended to address recruitment limitations and increase connectivity between remnant subpopulations.
