Black teatfish (Holothuria whitmaei) is a high value sea cucumber that has been listed under the Convention on International Trade of Endangered Species (CITES) Appendix II. The Black teatfish fishery in Torres Strait, Australia, is fished solely by Indigenous Torres Strait Islanders. Black teatfish were closed to fishing in 2003, based on the results of stock surveys and concerns of overexploitation. A stock survey in 2009 found the Black teatfish population had recovered substantially but the fishery was again closed after trial openings exceeded catch limits. In line with a new harvest strategy adopted for the fishery in 2019, we conducted a stock survey in 2019–2020 that suggested the stock had recovered sufficiently to support a sustainable catch limit of 20 t. Empowering Indigenous Torres Strait Islanders to use Island custom alongside western management strategies, contributed to the success of a trial opening in 2021. The combination of a harvest strategy developed in consultation with traditional owners, a rigorous scientific survey and trial opening protocols informed by Island custom, supported the CITES positive Non‐Detriment Finding for the Torres Strait Bêche‐de‐mer Fishery. This is a significant example of the successful recovery and ongoing sustainable management of a depleted sea cucumber population. [ABSTRACT FROM AUTHOR]

Fish traps and fish weirs built by Indigenous people in the Barwon‐Darling River system of the Murray Darling Basin (MDB), south‐eastern Australia, are an important component of their traditional social, spiritual and economic systems. The celebrated Brewarrina stone fish traps (Ngunnhu) on the Barwon River are the largest and best documented stone fish traps in the Basin. However, there has been minimal research on the many other stone fish traps in this system. This paper focusses on the in‐stream stone fish traps downstream of Brewarrina along the Darling (Baaka) River, some still partly extant, remembered, or documented in historical material. Wooden and earthen bank fish traps and weirs, while not as enduring and archaeologically visible as stone fish traps, were frequently used on the Darling (Baaka) floodplain lakes, swamps and billabongs. Archaeological evidence, traditional cultural knowledge and historical materials are utilised to document the complex social processes and modification of landscapes associated with fish traps and weirs. By demonstrating that Barkandji were active and successful managers of the river and its ecology prior to colonisation, and that much of this cultural knowledge is retained by current generations, the authors make a case for them to renew their custodianship and a decision‐making role in water management.

Archaeological approaches to stone-walled tidal fish traps of Indigenous Australians focus on technology and subsistence, with chronological development linked to demands of increased food production associated with demographic change and social intensification. For the Yanyuwa 'Saltwater People' of tropical northern Australia, old stone-walled fish traps found within the intertidal zone are associated with the creative acts of ancestral spirit beings. As such, these fish traps are imbued with spiritual potency and agency such that use requires specialized ritual practices (involving ochre and smoke) by senior men who also prescribe who can and cannot use the traps and eat the resulting catch. Today these traps lie dormant, not because the demand for fish has decreased but because of the demise of old highly initiated men of Law. These senior men not only possessed the requisite ritual knowledge to repair and activate the traps but also the specialized social and political knowledge to ensure adherence to strict and religiously codified laws and rules governing fish catch consumption amongst the community. The Yanyuwa teach us that socio-religious and socio-political factors can in certain contexts be of equal or greater importance than socio-economic factors in understanding why peoples of the past decided to use and dis-use fish trap facilities.
