Fish traps and weirs

Names

The dictionary has no noun for a fish trap, weir or fish fence^[3]. Two verbs describe what such structures do: wukurril 'follow; weave; make a fence; imitate' and kanbil 'to block, put in the way of'. Most traps in the record were made of split lawyer cane, called milmarr 'edible lawyer cane', with mawar for 'the vine of the lawyer cane'^[3]. Roth gave the Bloomfield name of the large lawyer cane, Calamus australis, as milma (his spelling). In the Cairns district that cane was split for fish and wallaby traps^[1][5].

Description

Roth's North Queensland record has five kinds of trap^[1]:

• Cane cages: long funnels of split lawyer cane laid in a creek, mouth upstream.
• Stone dams and weirs: walls of rock across a stream, with gaps where the fish are caught.
• Brush fences: saplings or bushes set across a flooded stream or a tidal creek.
• Moving grass fences: a line of people pushing grass and boughs through a waterhole.
• Hollow logs: left lying in a waterhole for eels, crayfish and fish to shelter in.

What is recorded for Kuku Yalanji. Anderson gives three main ways the Bloomfield people got fish: spearing, hook and line, and plant poisons. Traps are not among them^[2]. Roth collected 112 artefacts on the Bloomfield. The two fish traps in his collection both come from Atherton^[6]. So eel traps are not recorded for Kuku Yalanji in these sources. The nearest recorded eel traps are the cane cages of the Tully, Atherton, the Barron, Russell and Mulgrave, among rainforest peoples to the south^[1].

Today a Kuku Yalanji cultural tour guided by Traditional Custodians shows visitors 'ancient fish traps engineered from stone and tidal knowledge' at Rocky Point^[4]. No published survey of those traps was found.

Where and when

• Falling floods. Stone dams were 'greatly adopted after floods when the waters are going down'. Brush fences were used 'only in flood time' to catch the bigger fish as they returned downstream^[1]. The dictionary's word for a flood is jalungkarr^[3].
• Shallow creeks. Cane cages were laid in a shallow part of the creek^[1].
• Tides. On Sweers, Bentinck and Mornington Islands in the Gulf, curved stone walls up to 300 yards out from shore stopped fish going back to sea on the falling tide. Near Mapoon, a bush fence in a tidal creek held fish that came in on the rising tide^[1].
• Eel cages. On the Tully they were set in the daytime, left all night and lifted in the morning^[1].
• Hollow logs. They were left for three or four hours, or all day. Roth first saw them worked in November 1898, near the Musgrave Telegraph Station^[1].

The upper Mitchell. No trap or weir is recorded for Western Yalanji country in these sources. Roth's nearest inland records are those hollow logs, and a brush fence 100 feet long near the head of Birthday Creek, Princess Charlotte Bay^[1]. Only about 4% of the Mitchell catchment's rain falls between May and October^[7], so a flood fence there would belong to the end of the wet.

What they caught

• Cane cages: 'usually eel' around Atherton and on the Barron, Russell and Mulgrave; eels again on the Tully. The mesh was made to suit the size of fish wanted^[1]. See eels.
• Stone dams and brush fences: 'the bigger fish' coming back down after a flood. Roth does not name the species^[1].
• Hollow logs: crayfish, eels, and fish 'somewhat resembling rock-cod'^[1]. See cherabin.
• Grass fences: whatever fish were in the hole^[1].

How they were built and fished

Lawyer-cane cage (Atherton and Cairns districts)^[5][1][6]:

1. Split lawyer cane into strips and sort them into lengths.
2. Bend three or four strips sharply to make the pointed end.
3. Weave two continuous strands in and out of them in a chain-twist. Keep going in a spiral towards the mouth, adding strips as the cage widens.
4. At the mouth, cut the ends of the strips level and bend them outwards. A cage took three to four hours to make.
5. The finished cage is 3–4 feet long and up to 6 or 7 inches across. The two in the Australian Museum are 97 and 108.7 cm long, with mouths 18 and 21 cm wide.
6. Lay it lengthwise in a shallow part of the creek, mouth upstream. Wedge it with rocks set at an angle across the water.
7. Men beat the water further up the creek and drive the fish down into it.

Tully River eel trap (Mallanpara country, far south of Kuku Yalanji country)^[1]:

1. Use a funnel-shaped cage (kau). Line its inside with fine water-grass.
2. Drive sticks upright in two lines spreading out from the mouth in a V, and weave blady grass through them so that fish can pass only into the trap.
3. Set it in the daytime, leave it all night and lift it in the morning.
4. To drive out an eel hiding in a hollow log, hold the cage at one end and push a lawyer cane with a frayed end in from the other. If the chewed end comes out slimy, an eel is inside.

Stone dam^[1]:

1. As a flood goes down, build a wall of rocks and stones right across the stream.
2. Leave gaps (breaks) for the water to rush through.
3. Below each gap, build a stone platform covered with boughs and then grass; the fish stick in the grass as the water drops. On the Russell, Barron and Mulgrave, a cane cage at the gap took the place of the platform.

Brush fence (Birthday Creek, Princess Charlotte Bay, 1898)^[1]:

1. Stand five or six upright forked posts across the stream, and lay long logs in the forks at the height of the flood water.
2. Stick dozens of saplings, 8–10 feet long, into the mud so that they lean on the upstream side of the logs.
3. Leave two gaps about a foot wide near the ends, with nets on the downstream side.
4. As the water falls, spear the fish left along the foot of the fence.

Hollow log (Princess Charlotte Bay hinterland)^[1]:

1. Throw hollow paperbark or bloodwood logs, 4–7 feet long, into a waterhole.
2. Come back hours later. Dive down and bring each log up at an angle, one hand closing the lower end.
3. Let the water trickle out through your fingers to feel whether anything is inside.

Grass fence (Cape York Peninsula, and the east coast as far south as the Tully)^[1]: the women of the camp line up across a shallow waterhole on hands and knees. They push thick bundles of grass and leafy boughs ahead of them and drive the fish against the bank.

Safety

Eels bite. On the Tully, men who grabbed speared eels by hand were often 'severely bitten'^[1]. Floodwater is strong and full of snags, so never wade or dive into a flooded creek to set or check a trap. Waterholes and tidal creeks can hold crocodiles; see freshwater crocodile and saltwater crocodile.

On Country today

Aboriginal tradition. Queensland's Fisheries Act 1994 gives an Aboriginal person acting under Aboriginal tradition a defence for personal, domestic or non-commercial communal fishing with prescribed gear outside prescribed waters^[8]. The regulation prescribes a fish trap, meaning 'a structure made predominantly from stone or organic material that creates a holding area designed to capture a small quantity of fish'^[9]. Section 211 of the Native Title Act 1993 also frees native title holders from licence and permit requirements for those needs^[10].

Everyone else. In Queensland fresh waters a recreational fisher may use up to four tagged traps of listed kinds: canister, collapsible, dilly net, funnel or round, and open-top pyramid traps^[11]. A cane cage or brush fence is not on that list. A dam, weir or other barrier that limits fish movement in a waterway is a 'waterway barrier works', and building one needs development approval^[8].

Old traps are heritage. Stone fish traps are Aboriginal cultural heritage. Harming, moving or taking it is an offence in Queensland^[12]. Leave old stone walls as they are.

Western Yalanji country. The 2013 determinations recognise rights to hunt, fish and gather for personal, domestic and non-commercial communal purposes^[13]. A further determination followed in August 2026^[14]. At Karma Waters the station closes from 1 December to 1 April, partly to give fish and prawns an undisturbed spawning season^[15]. Ask the Traditional Owners and the station before building anything in the river.

Language

Kuyu 'fish'; wawubaja 'river'; bana 'water'; jalungkarr 'flood'; marral 'dry'^[3].
