Immuno-staining of a ciliate protozoan causing significant mortalilty of farmed tuna: the development of a rapid identification technique which will enable improved farm management practices to be implemented to minimise fish mortality

An immunofluorescent staining technique for the rapid detection of the ciliate protozoan Uronema sp. was developed during 1995 and 1996. The initial test was developed using seven cultures of Uronema sp. from various sources which were identified as Uronema nigricans by microscopical and...

Need

A large spawning aggregation of giant Australian cuttlefish (Sepia apama) usually occurs on a discrete area of rocky reef adjacent to Pt Lowly in northern Spencer Gulf. This is the only known dense aggregation of spawning cuttlefish in the world and it is highly valued by local residents, the tourism industry, and recreational divers. A cephalopod fishing closure was established in the spawning area in 1998 due to a rapid increase in catches in the area and concerns about the sustainability of the resource.

A series of anecdotal reports, filtered through various media sources, has indicated that this year’s (2011) spawning aggregation appears significantly reduced. There is considerable speculation as to why breeding cuttlefish have “failed to turn up” on the Point Lowly Peninsula spawning grounds, ranging from natural variation in their population dynamics, localised pollution by coastal industrial development, and environmental irregularities. In order to effectively respond to this decline, it is important to determine whether it is an ongoing trend, and if so, what its cause is. Structured cuttlefish surveys, where the data have been made publically available, have not occurred since 2005 (see Steer and Hall, 2005), therefore, it is has not possible to ascertain the magnitude of the annual variation in cuttlefish abundance and biomass. Furthermore, there has not been any structured environmental monitoring within the broader northern Spencer Gulf area to investigate any potential casual links between local environmental conditions and cuttlefish aggregative behaviour. Clearly there is a need to develop an on-going monitoring program that quantifies the abundance and biomass of cuttlefish on the spawning grounds, coupled with a structured environmental monitoring program. This is of particular importance as the spawning grounds are located in close proximity to coastal industry and proposed further infrastructure development.

Objectives

1. To develop a ‘standard’ methodology that can be used in the on-going monitoring and assessment of the unique cuttlefish population and the environment in which they aggregate to spawn.
2. To develop a preliminary understanding of whether there have been declines in abundance of the spawning aggregation, and the causes of any decline observed.

PIRSA: Surveying, searching and promoting cuttlefish spawning activity in northern Spencer Gulf

The size of the Giant Australian Cuttlefish (Sepia apama) population on the Point Lowly spawning grounds in 2014 increased for the first time since 2009, yet management is remaining cautiously optimistic as the reason for this increase is currently unknown. In addition to the annual assessment...
