“…Voucher data include images, field notes, museum specimens (skeletons) and others. Conditions of individuals studied ranged from 1 to 5 (alive to mummified or skeletal remains; Geraci and Lounsbury, 1993) (Fragoso, 2001;Montes-Iturrizaga, 2003) or published (Ramos et al, 2001;Montes et al, 2004;Van Bressem et al, 2006b). …”

“…Interactions with fisheries are thought to have caused these injuries in at least 70.5% of the affected animals. In addition, remains of nylon gillnets were seen in five S. guianensis from Sepetiba Bay ( Figure 6b) and two from northern RJ (Fragoso, 2001;Ramos et al, 2001; Table 5). In a number of species, incisive wounds and scars possibly inflicted by propellers are currently under study, in an effort to identify confirmed cases (see Van Waerebeek et al, 2007, this volume).…”

“…Miscellaneous non-infectious diseases, lesions, anomalies and traumata are also commonly found in SA small cetaceans (e.g. Van Bressem et al, 2000;2006b;Ramos et al, 2001;Sánchez et al, 2002;Flores et al, 2005 18 ; Flach, 2006 19 ; Laeta et al, 2006 20 ; Mendonça de Souza et al, 2006 21 ) and may also have a negative impact on reproductive success, impair feeding or cause premature death (Van Bressem et al, 2000;2006b;Ramos et al, 2001;Sánchez et al, 2002;Siciliano et al, in press). Anthropogenic activities may influence the c o u r s e o f d i s e a s e s a s w e l l a s d i r e c t l y c a u s e traumata and lesions (Van Bressem et al, 1994;2001b;Ross, 2002;Viddi et al, 2005 22 ; Flach, 2006 19 ).…”

ABSTRACT:We succinctly review and document new cases of diseases of the skin and the skeletal system and external traumata in cetaceans from Ecuador, Colombia, Peru, Chile, Argentina, Uruguay, Brazil, and Venezuela. The survey revealed 590 cases diagnosed with a significant pathology, injury or malformation on a total of 7635 specimens of 12 odontocete species examined or observed in . Tattoo skin disease (TSD), lobomycosis-like disease (LLD) and cutaneous diseases of unknown aetiology seem to be emerging in several populations. TSD was confirmed in eight species from the SE Pacific and SW Atlantic. LLD affected only inshore Tursiops truncatus but was found in four tropical countries, namely Colombia, Ecuador, Peru and Brazil. Lobomycosis was confirmed by histology in one male from the Tramandaí estuary, southern Brazil. All LLD-affected specimens were encountered in the vicinity of major ports and cities and a possible association with chemical or organic water pollution is suspected. Whitish velvety cutaneous marks associated with scars occurred in inshore T. truncatus, Sotalia guianensis and Pseudorca crassidens. Large, rounded lesions were seen in a Cephalorhynchus eutropia calf and a C. commersonii. Cutaneous wounds and scars as well as body traumata possibly related to net entanglements and boat collisions were observed in 73 delphinids and Phocoena spinipinnis. Traumatic injuries resulted in the partial or complete amputation and other disfiguring scars of appendages in 17 cases. Fractures of the skull, ribs and vertebrae thought to be caused by fisheries-related interactions or boat collisions were seen in single individuals of Delphinus capensis, Lagenorhynchus obscurus, T. truncatus, S. guianensis and Ziphius cavirostris. Prevalence of osteopathology in small cetaceans from Peru, Brazil and Venezuela ranged widely, from 5.4% to 69.1%. In four species from Peru, lytic cranial lesions were the most frequently observed disease (5.4%-42.9%), followed by hyperostosis and ankylosing spondylitis in offshore (31%, n=42) and inshore (15.4%, n=26) T. truncatus. Fractures and other bone traumata were present in 47.2% of 53 axial skeletons of S. guianensis from the northern Rio de Janeiro state (Brazil) in 1987-1998. A high prevalence (48.4%, n=31) of, apparently congenital, malformations of cervical vertebrae, observed in a 2001-2006 sample, may be explained by a hypothetical genetic bottleneck in this population. Malformations with deficient ossification would clearly increase susceptibility for fractures. This study demonstrates the utility of a continent-wide analysis to discern epizootiological trends more readily than any local study could provide. Secondly, it underscores the need for focussed research on the effects of human activities on the spread of diseases in cetaceans, particularly in near-shore populations that utilize highly degraded coastal habitats.

“…Debris collected from other North Sea coastlines such as Germany, the Netherlands, Belgium, France, Norway and Denmark, has been largely attributed to shipping and fishing activity (Galgani et al, 2000;van Franecker et al, 2005;Vauck and Schrey, 1987). Furthermore, fishing gear, operational as well as floating fragments, has been shown to cause entangling and mortality of marine animals (Derraik, 2002) including seabirds (Bugoni et al, 2008;Simeone et al, 1999;Stempniewicz, 1994;Votier et al, 2011;Zador et al, 2008), cetaceans (Johnson et al, 2005;Neilson et al, 2009;Ramos et al, 2011;Robbins and Matilla, 2004), turtles (Carr, 1987), sharks (Sazima et al, 2002) and seals (Hanni and Pyle, 2000;Hofmeyr et al, 2006;Page et al, 2004).…”

Marine debris from ships has persisted and remains a concern despite international agreements such as MARPOL. We report on an analysis of beach litter based on a data set established by the Marine Conservation Society (MSC) Beachwatch weekends. Debris collected around the UK was divided into three main types of debris: (1) plastic (2) fishing, (3) fishing related plastic and rubber. Correspondence analysis (CA) was used to examine patterns in the occurrence of debris types on a total of 1023 beaches and debris attributable to fishing was identified on clusters of beaches mainly located on the coasts of Scotland and along the English Channel. General Linear model (GLM) identified fishing as the highest explanatory factor when testing for relationships between litter and proximity to fishing ports and grounds. The results add to the growing body of evidence that the fishing industry is largely responsible for marine debris.
