Anyone been catyching any jellyfish lately? I saw this and thought it was interesting. I didn't really think we had enough jelly fish in victoria to bother setting up a commercial fishery but apparently we do! :cry:

OPEN FOR PUBLIC COMMENT

Environmental Assessment of the Victorian Developmental Jellyfish Fishery under the EPBC Act (Victoria)

Source & full text: http://www.deh.gov.a...ries/index.html

Closing date for comments is Friday 10 November 2006.

The Department of the Environment and Heritage (DEH) has received a submission – Statement of Management Arrangements for the Victorian Developmental Jellyfish Fishery (Catostylus mosaicus) from the Department of Primary Industries, Victoria. The report has been prepared against the Australian Government Guidelines for the Ecologically Sustainable Management of Fisheries (the Guidelines). The submission will be used to assess the operation of the fishery for the purposes of Part 13A of the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act).

Consideration will be given to:

- declaring the Victorian Developmental Jellyfish Fishery, as managed consistent with the Victorian Fisheries Act 1995 , as an Approved Wildlife Trade Operation under section 303FN of the EPBC Act; and

- including on the list of exempt native specimens, specimens harvested in the Victorian Developmental Jellyfish Fishery in accordance with the Victorian Fisheries Act 1995.

In accordance with the provisions of sections 303FR and 303DC of the EPBC Act, you are invited to comment on this proposal.

Electronic copies of the Guidelines and the submission are available from the DEH website at http://www.deh.gov.a...ries/index.html

Here is an exert from the Victorian management plan:

DEVELOPMENTAL FISHERIES MANAGEMENT PLAN
FISHERIES DIVISION - DEPARTMENT OF NATURAL RESOURCES AND ENVIRONMENT
JELLYFISH - (Catostylus mosaicus) 2003 - 2005


1. Background
Dried jellyfish (sold mostly in dried discs of 30 – 40 cm in diameter) is a highly
regarded food item in many Asian countries, especially in Japan where it is
considered to be a delicacy. Traditionally, jellyfish are a food source comprising
low fat and high protein qualities, which are recognised for their health qualities.
The basis of quality assessment is on size, texture, colour and especially in Japan
the crunchiness of the dry salted product.

The Chinese and Japanese jellyfish markets are currently supplied with catch taken
in Thailand, Malaysia and China, but increasing demand has created opportunities
for Australian involvement. Market research indicates a shortage in both Chinese
and Japanese markets and importers could accept 1000 processed tonnes (10,000
wet tonnes) at USD $8-10 (AUS $13 - $16) per wholesale processed kilo (Grade B
product). The demand for jellyfish product is growing by 25% per annum.

The Rhizostome jellyfish Catostylus mosaicus is an Australian (Eastern and
Northern seaboards) native species and is often found in large numbers in
Victoria's bays and inlets.
This species has been shown through marketing trials
carried out by David Glory Group Pty Ltd to be acceptable to the Asian market.
Estimates indicate that several thousand tonnes can be taken during some years
from Port Phillip, Western Port and Corner Inlet. The developmental fishery was
activated in 1999 following the release of the report titled "Feasibility Study for
the Development of a Commercial Jellyfish Fishery in Port Phillip Bay, Victoria,
MAFRI, (November 1997)". The report indicated that in Port Phillip Bay alone
there is a biomass of C. mosaicus ranging from 5,000 to 30,000 tonnes during the
summer and autumn months from February to June.

More recent MAFRI research suggests that the abundance is extremely variable. In 2001 the commercial biomass ranged from 7,500 wet tonnes to 17,000 wet tonnes. In 2001 this was down by 80%. Initial
indications are that the species was most abundant in Port Phillip Bay and Corner
Inlet. Stock abundance are likely to be connected to water temperature and
salinity.

That is interesting. I see a lot of different jellyfish while kayaking and diving, I was interested in which particular one the fishery is targetting, so I googled the scientific name - the first thing I found out was that the sceintific name of the jellyfish was misspelt in the initial document, it should have been Catostylus mosaicus. The jellies are the big 'classic' looking jellyfish which are common in PPB at different times of the year. I found the picture below at http://www2.eve.ucda...mosaicus_i.html, it is of one of these jellies in the Georges river, NSW.

Hi jazman, thanks for pointing out those spelling errors. It was actually spelt wrong in the article at the top plus in the main text of the second article and so I have fixed the mistakes.

See below for another picture of the jellyfish out of the water (from the management plan referred to above). I have seen these jellyfish while floundering at night.

Has anyone ever tried eating dried jellyfish before?

I have never seen it for sale but i am guessing you could buy it in asian grocery stores.

Cheers, Glen :cry:

i've seen heaps of these while floundering, and also washed up on beaches

i never knew that there was anything edible on the jellies, but i guess if there is, trust the chinese and japanese to have found it out.

the management plan says they are supposed to be high in protein.

however, i would have thought they were 99% water so it seems like a lot of effort to get that 1%!!! :cry:

yah they are definitely edible! usually served cold with vinegar dressing. I guess they will strink too much if you cook it. Its not much of a flavor to eat, but they have a very special crunchy texture. I dont think these are poisous species since we eat both the body and the tenticles :th
