As with many other reptiles, the sex of a marine turtle embryo is determined by the temperature of the nest in which the eggs incubate. Warmer sand temperatures (>29°C) produce mostly female hatchlings, whilst cooler temperatures produce predominately males (<29°C). Scientists are concerned that due to human induced climate change, there will be an increase in female hatchlings, known as feminisation, leading to a decline in overall population due to the lack of male production.

Invertebrate surveys allow us to understand the status of species populations, not just what is caught. Data, such as abundance and length, are used to calculate stock densities and track sizes and help develop management strategies for the sustainable use of fisheries resources.
The BIEM Initiative, KRA 5 of PEUMP, implemented by the Secretariat of the Pacific Regional Environment Programme (SPREP) supported a collaboration between World Wide Fund for Nature Pacific (WWF-Pacific) and the Fiji National University’s Fiji Maritime Academy (FMA) to provide certification training to fishing crew in Fiji’s longline tuna industry.
To reduce mortality of by-catch and endangered, threatened, and protected (ETP) species mortality and encourage safer by-catch handling in Fiji's offshore fishing industry, 54 by-catch mitigation toolkits have been distributed to Fiji Fishing Industry Association (FFIA) member longline fishing vessels.
The supply of the by-catch mitigation toolkits was supported by the By-catch and Integrated Ecosystem Management (BIEM) Initiative implemented by SPREP under the Pacific-European Union Marine Partnership (PEUMP) Programme funded by the European Union and the Government of Sweden.
11 February marks the International Day of Women and Girls in Science. The day focuses on the vital role of gender equality in science, for the achievement of internationally agreed development goals, including the UN 2030 Agenda for Sustainable Development.
