“…These obviously reflected a poor health condition, presumably induced by the xenobiotics. Furthermore, the pathology observed in H mussels, together with that reported for experimental treatments by Rasmussen et al (1983aRasmussen et al ( ,b, 1985, confirm that the digestive gland is a target tissue for xenobiotic effects (Sindermann 1980).…”

This comparative histopathological study, carried out at the GEEP Workshop, assesses tissue changes in mussels Mytilus edulis from a contaminated Norwegian fjord and from mesocosm basins where a contaminant gradient had been simulated. Parasitism by larval trematodes was observed in both circumstances, but was not related to contaminant levels. Mussels from the field exhibited granulocytomas in their interstitial tissues, with a greater incidence at polluted sites than at a reference site, suggesting that granulocytomas could be a consequence of chronic pollutant exposure. This pathological condition was not observed in experimentally treated mussels, which nevertheless had severe tissue alterations, especially in digestive tubules and gills, under exposure to high levels of a diesel oil and copper mixture. It is concluded that this type of histopathological analysis can provide useful information on the health of mussels, and that this information can be used successfully in the comparison of field samples.

“…Digestive cells are characterized by a well-developed endolysosomal system. Basophilic cells are secretory cells which are involved in the synthesis and secretion of 215 (Rasmussen et al 1983, Lowe & Clarke 1989, Cajaraville et al 1990, Zorita et al 2006). This apparent cell type replacement is the result of digestive cell loss and concomitant basophilic cell hypertrophy (Zaldibar et al 2007) and is measured in terms of Vv BAS .…”

Mussels Mytilus galloprovincialis were collected monthly in 2 localities in the Northern Iberian Peninsula, Oia (Galicia) and Mundaka (Basque Coast), from April 2005 to May 2006, to investigate whether seasonal variability in biomarkers follows the same pattern at both geographical areas. The following battery of biomarkers was analysed: lysosomal membrane stability and structural changes, intracellular neutral lipid accumulation, cell type composition in the digestive gland epithelium, structural changes of digestive alveoli and digestive gland histopathology. Additionally, gonad index was measured as a supporting parameter. Overall, results demonstrate that most studied biomarkers showed similar seasonal variability pattern in both localities. Lysosomal membrane stability (labilisation period [LP]) and most histopathological conditions showed similar seasonal variability patterns in both localities, although values of LP and prevalences of some parasites were higher in Mundaka. Data provide baseline values to be used as reference values for the biomonitoring programmes carried out in coastal areas from Galicia to the Basque Coast. It is concluded that for monitoring programmes based on biomarkers, samples must be taken at least twice per year (spring and autumn) to avoid the effect on biomarkers of the late stages of each reproductive cycle.

This study looked into recovery rate and histological changes in the gills of juvenile abalone Haliotis discus hannai by exposure time (3, 6, 12, 24 and 48 h) of different water temperatures (15, 20 and 25℃) and salinities (30, 25, 20 and 15 psu) to understand reasons for the death of abalone exposed by low salinity water. In each water temperature, abalone spats that were exposed to low salinity water (less than 20 psu) for over 6 hours showed decrease in survival rate during recovery and those were exposed at the salinity of 15 psu for more than 24 hours all died. Histological observation showed expansion or damage of gills of the species which were exposed at less than 20 psu for over 6 hours. In case of abalones exposed at the salinity of 15 psu for over 24 hours, most gill tissues were destroyed. This result was glaringly obvious at a higher water temperature, lower salinity and longer exposure time. Accordingly, suffocation caused by damage of gills considered one of direct causes of the death.
