The International Symposium on Stock Enhancement & Searanching


Welcome to the International Symposium on Stock Enhancement and Sea Ranching website. The ISSESR series began in Norway in 1997. The series was stimulated by continuing concern over the decline of fisheries, coupled with emerging technologies in marine aquaculture and new efforts to quantify the effects of stocking aquacultured organisms into the sea. These symposia, which are held every 4 to 5 years, have connected scientists and others interested in the efficacy of using aquaculture to help sustain, replenish, enhance or investigate exploited fish and invertebrate populations.

The 6th International Symposium on Stock Enhancement and Sea Ranching will be Co-convened with the Florida State University William R. Mote International Symposium on Fisheries Ecology
at Mote Marine Laboratory in Sarasota, Florida, USA.
10 to 14 November 2019
(Welcome Reception is 6-8 pm on 10 November 2019;
symposium presentations begin at 9 AM on 11 November 2019)

The Proceedings from the 5th International Sysmposium on Stock Enhancement and Sea Ranching is published in the Journal Fisheries Research Volume 186, Issue 4, Part 2:407-598 (February 2017)

The web site for the 6 th ISSESR is under construction. The call for abstracts is now open as of 1 April 2019. See instructions for Abstract submission


The International Symposium on Stock Enhancement and Sea Ranching -- At a Glance

Many of the world's marine fisheries no longer yield the benefits they once did, due to over fishing and degradation of the supporting ecosystems. Governments are responding to the fisheries crisis by reducing fishing efforts and protecting fisheries habitats. However, fisheries managers are also asking whether the advances in aquaculture, that now enable juveniles of many species to be produced en masse, can be applied to speed up recovery of some stocks, or increase the production of others.

The ISSESR symposiums have been hosted by Norway (1997), Japan (2002), the USA (2006) China (2011), and Australia (2015). More Background on this symposium series can be accessed here.

We invite you to join us also in Sarasota in 2019, at the Sixth International Symposium in this series, where the latest science and knowledge about the effects and effectiveness of stock enhancement, sea ranching and restocking will be presented.
