Thunnus alalunga is an important commercial tuna species widely distributed in the three major oceans and the Mediterranean Sea. The Mediterranean population is currently classified as a data-poor stock and little is known about its basic life history parameters. This study provides the first detailed information on some aspects of the reproductive biology of T. alalunga from the western Mediterranean Sea. A total of 16 104 specimens were measured between 2005 and 2012. The overall sex ratio of females to males was 1.1:1, although the ratio was female biased in fish <70 cm fork length (LF) and male biased in those >75 cm LF. Histological analysis of the ovaries (N = 587) and the monthly variation of the gonadosomatic index for both sexes showed that spawning occurred from June to August, which is a much shorter period than the 7 months reported for T. alalunga in tropical oceanic waters. Thunnus alalunga caught during June and July are capable of spawning daily. The gonadosomatic index values for T. alalunga from the western Mediterranean were up to eight times higher than those of T. alalunga from other oceans. Histological examination of the ovaries showed that the minimum length at sexual maturity of females was 56 cm LF, which is considerably smaller than those estimated for other stocks.

Dugong Dugong dugon Lacépède, 1799, a globally threatened marine mammal that occurs in the coastal waters of the Indian and Pacific Ocean, is traded in small numbers throughout their range. We surveyed 128 shops selling wildlife in seven (June 2013) and eight (July 2014) towns on the island of Bali, one of Indonesia's most popular tourist destinations. Dugongs are protected under Indonesian law and CITES Appendix I Iisting precludes international trade. Despite this dugong parts were observed in trade in Denpasar, Mengwi and Sanur where 14 traders were interviewed. We recorded over 130 dugong parts, including raw bones and teeth but also many carved items and some derivatives, with no noticeable difference between years. The most common items were cigarette pipes carved from, predominantly, dugong ribs, and decorative carvings from bone and teeth. The total value of the items observed was $1500–3000. The trade was open and qualitatively similar to trade in parts of non-protected species. Information from traders suggests that dugongs are caught throughout Indonesia, and are both targeted specifically and caught accidentally. It is imperative for the management of dugongs to take the illegal trade in dugong parts into account and for the authorities to curb the trade by taking appropriate action in line with Indonesia's legislation. Greater awareness of the plight of the dugong, including the impediments to their conservation posed by the illegal trade in body parts, by the residents of and visitors to Bali, may aid in pressuring the authorities to take these steps.
