This paper stems from the 3-year collaborative project that was implemented in 2008-2010 to monitor sea turtles in Drini Bay, Albania. It follows several previous papers and reports presenting project results. This paper provides a method of utilising morphometric data to understand population structure and a practical way of identifying the development of secondary sexual characteristics from external features, combining carapace and caudal measurements. We include the abstract at the end of this email and take the opportunity to once more acknowledge and thank project partners and funders. Following this project, Albania is working to implement the national sea turtle action plan adopted in 2012 through policies and projects such as NETCET.


Population Structure for Sea Turtles at Drini Bay: An Important Nearshore Foraging and Developmental Habitat in Albania
Abstract: Loggerhead sea turtles Caretta caretta using an important shallow-water foraging ground at Drini Bay, Albania, were monitored over 3 consecutive summers (2008–2010). Working closely with local artisanal fishermen, researchers were able to obtain many of the sea turtles captured as bycatch (nontarget species). There were 407 new records (402 loggerhead and 5 green turtles, Chelonia mydas), with most (99%) being captured in 2 stavnike fish traps (a type of pound net) and a few with mrezh (gill nets). Morphometric data were collected from all captured turtles, and they were allocated into 10-cm size classes (length-frequency-distribution) based on their curved carapace length; caudal measurements were used to assess the developmental-stage of secondary sexual characteristics. An unusually high number of male loggerhead turtles (27%) were captured; their morphometric data were subsequently used as a reference for determining if short-tailed turtles might be adult or sexually developing females. Nesting has not been reported for Albania, so the presence of females is unclear. Drini Bay is also a developmental habitat, as 69% of the studied turtles were yet to mature. Interannual recaptures of 26 turtles allowed their incremental growth rate to be calculated.
