Oysters
marrkabina · julul · juwarru · yulbaSaccostrea and other rock oysters
Seven words for oysters: marrkabina 'edible oyster'; julul 'kind of oyster, larger than juwarru'; juwarru 'mud oyster. It is like a barnacle, only it clings to rock and mangroves. Smaller and flatter than julul'; yulba 'large round oyster'; jirrum 'small oyster'; nikar 'species of shallow water oyster found on rock'; marku and marubu 'species of oyster'[1]. The rock oyster of this coast is Saccostrea, the hooded oyster, which 'cements itself to rocks or to the branches and roots of mangroves', grows to 8–12 cm in the Pacific, 'is a filter feeder' and 'is tolerant of a wide range of temperatures and salinities'[2]. Roth's rule for all shellfish was that 'the large majority of these shell-fish are roasted in the ashes: a few may be eaten raw', and that they were 'generally prepared by the women'; Anderson lists shellfish among the gathered foods at Bloomfield, with the oyster-growths of the reef and the creek mouths among the 'very important' areas of the Traditional Owners' plan[3][4][5]. This is a page of the sea country of the Eastern Kuku Yalanji, the Bloomfield and Daintree coast; it is a long way from Karma Waters on the upper Mitchell, and is here because the words, the trade and the tools reach inland.
Hann River Cape York
Possum People's country on the upper river and Thaypan (Kuku Thaypan) country downstream: stringybark and bloodwood woodland and a spring-fed sandy river that runs north-east from the Great Dividing Range, past the Peninsula Developmental Road, into Rinyirru (Lakefield) and the North Kennedy. Not Kuku Yalanji country: the Kuku Yalanji words on this page are the dictionary's, not the Hann's own languages. Place guide
No oysters live on the Hann. It is a freshwater river, and the Atlas of Living Australia holds no oyster records around the middle Hann[12]. The river's shellfish is the freshwater mussel: 'We get wallaby, barramundi, freshwater fish and turtles and mussels', a Thaypan man told the Federal Court[13].
The shellfish here
In a box of about 90 × 85 km around the middle Hann, Laura and western Rinyirru the Atlas holds just one bivalve record, a freshwater mussel (Velesunio angasi, 2000)[12]. Standley's work with the Kuku Thaypan Elders records that 'mussels were once larger and in high number across the entire wetland complex' of the Rinyirru lagoons, that they 'are periodically washed downstream during the wet', and that today 'mussels are no longer in abundant numbers'. Their signs of a healing lagoon include the 'Return of mussel numbers and increase in size'[14]. The rules about who may eat mussels from which places belong to the Elders' law and their families[14].
Down at the sea
The Hann's water reaches the sea in Princess Charlotte Bay[15], where mangroves fringe the coast: more than half of Cape York's low mangrove forest (regional ecosystem 3.1.2) grows in Rinyirru around the bay[16]. The shell mounds of the bay's mainland coast, between about 2,000 and 500 years old, are 'predominantly composed of the Anadara granosa shellfish species', the blood cockle, and older shell deposits in rock shelters go back about 4,700 years[17]. No published source names oysters among them.
Upper Mitchell Western Yalanji
Western Yalanji country west of the Great Dividing Range: dry open woodland cut by the sandy, paperbark-lined upper Mitchell River, around Karma Waters and Mount Carbine. Place guide
No oysters grow on the Western Yalanji Mitchell.
Here
There are no oysters at Karma Waters; the river's shellfish is the freshwater mussel.
Eastern coast Eastern Kuku Yalanji
Eastern Kuku Yalanji country: rainforest, beaches, mangroves, reef and the short steep rivers from the Daintree to the Bloomfield and the Annan.
The oysters of this page are the oysters of the Bloomfield and Daintree coast, the sea country of the Eastern Kuku Yalanji[5].
On country today
Oysters are gathered at low tide on the Bloomfield coast as they always were, and the eight dictionary words are a field guide waiting for its photographs; the contribution box below is for them[1].
Everywhere
Names
marrkabina 'edible oyster'; julul 'kind of oyster, larger than juwarru'; juwarru 'mud oyster ... clings to rock and mangroves. Smaller and flatter than julul'; yulba 'large round oyster'; jirrum 'small oyster'; nikar 'species of shallow water oyster found on rock'; marku 'species of oyster'; marubu 'species of oyster'; milbar 'generic term for shell'[1]. The dictionary sorts oysters by size and where they sit, which is how a gatherer sorts them.
The oyster
'The appearance and form of the hooded oyster is very variable. The shape is sometimes nearly circular or it may be oblong or roughly oval, often with an irregular outline. In the Mediterranean, it grows to 4 to 6 cm, but achieves double that size in the Pacific Ocean. The valves are thick and solid. The lower valve is convex and has no sculpturing near the umbo, which is fixed to the substrate. The upper valve is flat'. 'The hooded oyster is a filter feeder, pumping water through its gills and removing the phytoplankton. In polluted waters, it accumulates heavy metals in its tissues. For this reason it can be used as a bioindicator'. 'The hooded oyster is tolerant of a wide range of temperatures and salinities'. It 'cements itself to rocks or to the branches and roots of mangroves'[2].
On the Gulf islands Roth saw stone fish-weirs 'built of pieces of stone (subsequently locked together by oyster-growths)', which is how fast and how hard the oyster builds[3]. The estuary stingray 'has gained infamy for consuming farmed shellfish such as oysters', though it mainly eats crabs and worms[6].
Oyster, mussel, cockle
- Rock and mangrove oysters: cemented down, flat-lidded, irregular, in clusters[2].
- Saltwater mussels and the mangrove cockles (Geloina): two matching valves, held by threads in the mud or roots, not cemented[4].
- The big bailer and nautilus: not food on the rock but tools on the beach[7].
- Barnacles, which the dictionary's juwarru 'is like', are not shellfish at all[1].
Signs
Where they grow
Between the tides on rock and on mangrove roots, at creek mouths, on the headlands and the reef flats of the Bloomfield and Daintree coast and the islands; the Traditional Owners' plan names the reefs, mangroves and mudflats as the important areas[2][5].
The filter on the rock
The oyster filters the creek, cements the rocks and the weirs, and feeds the stingray, the crabs and the people; because it filters, it carries whatever is in the water, which is the one caution about eating it[2]. It sits in the mangroves' nursery with the mud crab, and the shell went into the earth oven ashes and the middens[3].
Seasons
Gathered at low tide in any season; the big spring low tides of the dry are the easiest; the shellfish 'generally prepared by the women'[3]. See the year on country.
Uses
Gathering oysters
From Roth and the dictionary[3][1]:
- Go at low tide (ngajal) to the rocks and mangrove roots at a creek mouth[1].
- Knock the big ones off with a stone or open them on the rock with a shell or a knife; the dictionary's julul and yulba are the ones worth the work[1].
- Roast them in the ashes until they open, 'the large majority of these shell-fish are roasted in the ashes', or eat the clean rock ones raw[3].
- Leave the small ones, jirrum, and the middens[1][8].
Safety
- Oysters concentrate what is in the water; none from a creek below a town, a drain or a boat ramp[2].
- Creek mouths and mangrove roots are crocodile country; Be Crocwise[9].
- Shell edges cut; boots and a glove.
- Taking shellfish on sea country comes under the Traditional Owners' plan, the Marine Park's traditional-use rules and the Fisheries Act 1994[5][10][11].
Language
marrkabina 'edible oyster'; julul, juwarru, yulba, jirrum, nikar, marku, marubu kinds of oyster; milbar 'shell'; ngajal 'low tide'[1].
