“…These studies so far found that although D. polymorpha is able to settle earlier in the season, is more salinity tolerant, and predators seem to target this species less than D. bugensis, D. bugensis usually remains dominant where both species co-occur (Karatayev et al 2014;Naddafi and Rudstam 2014;D'Hont et al 2018). Dreissena bugensis is able to settle in a wider range of habitats, is found at a greater depth range, grows faster and larger and adjusts its growth and settlement better to seasonally and annually varying salinities and temperatures than D. polymorpha (Claxton and Mackie 1998;Orlova et al 2005;Gerstenberger et al 2011;Metz et al 2018). Dreissena bugensis is known to have a higher assimilation efficiency, a higher activity of certain enzymes, higher filtration rates and lower respiration rates (Stoeckmann 2003;Ram et al 2012;Karatayev et al 2014).…”

Dreissenids’ breaking loose: differential attachment as a possible driver of the dominance shift between two invasive mussel species

Ponto-Caspian dreissenids are notorious freshwater invaders. Recently, widespread observations show a dominance shift from the early invader, Dreissena polymorpha, to its successor, Dreissena bugensis. These observations likely reflect congeneric species differences in physiological and behavioural traits. Here, we assessed the mussel attachment strength, attachment rate, and the mode of byssal failure as trait differences that could potentially contribute to dominance shifts. The attachment traits were measured in field and laboratory experiments. Fouling plates were deployed in the Rhine-Meuse river delta and dreissenids were collected and acclimatised in 60 L non-aerated freshwater tanks. Attachment strength was positively correlated with shell size. The attachment strength of D. bugensis was significantly greater compared to slower growing D. polymorpha individuals of a dreissenid field assemblage. This corresponded to the superior byssal thread morphology of D. bugensis (i.e. higher number and two times wider byssal threads). Moreover, our results indicated that byssal threads of D. bugensis are stronger than those of D. polymorpha, as the latter ruptured more often. Additionally, D. bugensis had a significantly lower attachment rate than D. polymorpha. Having a greater attachment strength gives D. bugensis an advantage when it comes to withstanding currents and predators. On the other hand, not being attached allows an individual to actively move around. This would allow them to move away from fast changing unfavourable environmental conditions. These attachment traits indicate competitive benefits for D. bugensis over D. polymorpha, therefore possibly contributing to the dominance shifts.

“…This could be especially useful in systems where mussels reach maturity within a couple of months and reproduce for many months throughout the year, as occurs in the warm, productive reservoirs of the southwestern USA (e.g., Gerstenberger et al. 2011; Culver et al. 2015).…”

“…For example, penning Bluegill under or around mussel-infested infrastructure (water towers, floating restrooms, pump barges, and docks) would likely eliminate the need to clean the structures frequently during periods of high mussel recruitment-a costly, labor-intensive tactic. This could be especially useful in systems where mussels reach maturity within a couple of months and reproduce for many months throughout the year, as occurs in the warm, productive reservoirs of the southwestern USA (e.g., Gerstenberger et al 2011;Culver et al 2015). In such systems, mussels would have to be physically removed approximately every 6-8 weeks for several months to prevent maturation and reproduction.…”

The quagga mussel, Dreissena bugensis, is a harmful aquatic pest that invaded the Southwestern United States in 2007. Challenges with managing this pest have been encountered because the invaded systems are primarily open water sources used for human consumption and/or are connected to freshwater habitats containing threatened and endangered species. Existing chemical and physical control methods are undesirable, with use of some methods restricted or prohibited, because they pose risks to humans and ecosystems more broadly. To address this problem, we investigated the efficacy of using resident fishes as biocontrol agents for managing different life stages of quagga mussels on different spatial scales in a site-specific manner. We conducted field experiments to test whether planktivorous Bluegill, Lepomis macrochirus, reduced mussel infestations on substrates of varying orientations in small and large pens through predation on larval mussels. We also conducted an experiment to evaluate whether the carnivorous Redear Sunfish, Lepomis microlophus, reduced mussel infestations established on substrates of varying orientations in small pens through predation on juvenile and adult mussels. Bluegills significantly reduced mussel infestations on all substrates in the pens through predation on larvae and small, juvenile mussels. Redear Sunfishes reduced existing juvenile and adult mussel populations in some cases, with consumption varying among individuals and substrate orientation. Our results indicate that fishes, specifically Bluegill, may represent effective site-specific biocontrol agents for quagga mussels, reducing impacts on targeted infrastructure (e.g., water towers, docks, pipes) and habitats having different surface orientations by controlling more than one life stage of the pest. Development of an integrated pest management strategy, that considers application of this tactic in combination with others, would undoubtedly improve management of quagga mussels, and potentially congeneric zebra mussels, within lake and reservoir ecosystems.

“…Hajeb et al, in 2009 studied Hg level in commonly consumed marine fishes in Malaysia and the tuna species had the highest level (4.15 μg g −1 ) [26]. In America, Gerstenberger et al, in 2010 examined the levels of total mercury in a New Jersey grocery store Hg (0.407 mg g -1 ) was found in the canned white-style tuna than canned light-style tuna (0.118 mg g -1 ) [27]. In studies conducted in Spain, Bordajandi et al, in 2004 found Hg levels of 0.30 and 0.28 mg kg −1 in canned and frozen tuna, respectively [28].…”

B u çalışma, Türkiye'de pazarlanan konserve balıklarda kalan civa seviyelerini tanımlamaktadır. Toplamda 375 balık numunesi, cıva kalıntıları için Endüktif Çiftleşmiş Plazma Optik Emisyon Spektrometresi (ICP OES) ile analiz edilmiştir. Validasyon verilerinden niceleme limiti (LOQ) 0.008 ila 0.043 mg kg -1 arasında değişmiştir. Doğruluk ve kesinlik, %87.5 ile 109.3 arasında ve geri kazanım %10'un altında varyasyon katsayısı elde ederek iki konsantrasyon seviyesinde (30 ve 50 mg kg -1 ) geri kazanım deneyleri yoluyla değerlendirilmiştir. Ayrıca, bağıl standart sapma (RSD) %0.2 ila %9, genişletilmiş ölçüm belirsizliği %11.1 ile %19.2 arasında değişmiştir. Araştırılan örneklerde %4.8'i saptanabilir civa seviyesinde tespit edildi, ancak bu seviyeler yasal sınırların altındaydı. Hg düzeyi açısından türler arasında anlamlı bir ilişki yoktur (p<0.05). Türkiye'nin mevzuatına göre, örneklerin hiçbiri, maksimum 1.0 mg kg -1 sınırını aşmadı, ancak %1.3 Gıda ve Tarım Örgütü/Dünya Sağlık Örgütü (0.5 mg kg -1 ) tarafından önerilen sınırı aştı. Validasyon çalışması sonucunda elde edilen tekrarlanabilirlik limitlerinin hem NMKL 170 yöntemi ve Türk Gıda Kodeksine (Tebliğ No: 2014/2) hemde 2002/657/EC sayılı AB Komisyonu Kararı'na uygun olduğu bulunmuştur.
