AUSTRALIA - A scientific paper (Pitman, Haddy and Kloser) has been released assessing the impact of commercial fishing on the reproductive capacity (fecundity) of orange roughy.
 
Data from when exploitation began (1987–1992) is compared with current observations from the eastern Tasmanian stock.
 
Findings show that the ability to reproduce is negatively related to stock size, meaning that as the population of orange roughy declined fecundity per individual increased 41,145 (± 1,363) eggs in 1992 to 59,236 (± 1,047) eggs in 2010.
 
The fecundity per fish has increased by 73 per cent. Modelling this increase based on the 2006 stock assessment showed that the female spawning stock biomass was at 19 per cent of virgin levels, whereas the total reproductive potential was markedly higher and estimated to be at 32 per cent of virgin levels.

Inside the Industry

The Mid-Atlantic Fishery Management Council has scheduled a series of scoping hearings to gather public input for a proposed action to protect unmanaged forage species.

The proposed action would consider a prohibition on the development of new, or expansion of existing, directed fisheries on unmanaged forage species in the Mid-Atlantic until adequate scientific information is available to promote ecosystem sustainability.

The National Marine Educators Association has partnered with NOAA this year to offer all NMEA 2015 conference attendees an educational session on how free NOAA data can add functionality to navigation systems and maritime apps.

Session topics include nautical charts, tides and currents, seafloor data, buoy networking and weather, among others.
