A draft genome assembly of southern bluefin tuna Thunnus maccoyii
Tuna are large pelagic fish whose populations are close to panmixia. In addition, they are threatened species, so it is important for the maintenance and monitoring of genetic diversity that genetic information at a genome level be obtained. Here we report the draft assembly of the southern bluefin tuna genome and the collection of genome-wide sequence data for five other tuna species. We sampl...
متن کاملSpawning Dynamics and Size Related Trends in Reproductive Parameters of Southern Bluefin Tuna, Thunnus maccoyii
Knowledge of spawning behaviour and fecundity of fish is important for estimating the reproductive potential of a stock and for constructing appropriate statistical models for assessing sustainable catch levels. Estimates of length-based reproductive parameters are particularly important for determining potential annual fecundity as a function of fish size, but they are often difficult to estim...
متن کاملResults of health surveys of two species of farmed tuna: southern bluefin tuna (Thunnus maccoyii) in Australia and northern bluefin tuna (Thunnus thynnus) in the Mediterranean
Health of two farmed species of tuna was evaluated in farm surveys in Australia, Croatia and Spain. The results were discussed at tuna health workshop during EAFP 12th International Conference. While a wide range of parasites was found, few problems occurred during the surveys. The information obtained will be useful for future monitoring and research on health of farmed tuna. Introduction Fish...
متن کاملBranchial Pathomorphology of Southern Bluefin Tuna Thunnus maccoyii (Castelnau, 1872) Infected by Helminth and Copepodan Parasites
Three metazoan parasites, a monogenean Hexostoma thynni and two species of copepods Pseudocycnus appendiculatus and Euryphorus brachypterus are known to parasitize the gills of ranched southern bluefin tuna (SBT) and other tuna species. However, there is no detailed information describing the pathological response to infection by these parasites in this species. Wild southern bluefin tuna Thunn...
متن کاملDemographic Structure, Sex Ratio and Growth Rates of Southern Bluefin Tuna (Thunnus maccoyii) on the Spawning Ground
The demographics of the southern bluefin tuna (SBT) Thunnus maccoyii spawning stock were examined through a large-scale monitoring program of the Indonesian longline catch on the spawning ground between 1995 and 2012. The size and age structure of the spawning population has undergone significant changes since monitoring began. There has been a reduction in the relative abundance of larger/olde...
