Evidence of Fishing With Lure Hooks From Late Neolithic Serbia

Fishing with lure hooks at the Late Neolithic site of Vinča – Belo Brdo, Serbia

Authors:

Cristiani et al

Abstract:

The authors present an early evidence for the use of complex fishing techniques for obtaining variable fish resources in prehistoric south-east Europe as recovered at the Neolithic site of Vinča – Belo Brdo in Serbia. In particular, a group of bone artefacts have been analysed through the application of an integrated approach combining technological, use-wear, and residue analyses as well as the comparisons with ethnographic artefacts. The results of the functional analysis indicate that these artefacts were parts of lure hooks, i.e. composite hooks, probably used to catch large predatory fish. On methodological grounds, the discussion proposed in this paper could be relevant for other case studies worldwide where one finds prehistoric communities with evidence of fishing activities.

Salmon Fishing at the Pleistocene/Holocene Boundary in Alaska

Early human use of anadromous salmon in North America at 11,500 y ago

Authors:


Halffman et al

Abstract:

Salmon represented a critical resource for prehistoric foragers along the North Pacific Rim, and continue to be economically and culturally important; however, the origins of salmon exploitation remain unresolved. Here we report 11,500-y-old salmon associated with a cooking hearth and human burials from the Upward Sun River Site, near the modern extreme edge of salmon habitat in central Alaska. This represents the earliest known human use of salmon in North America. Ancient DNA analyses establish the species as Oncorhynchus keta (chum salmon), and stable isotope analyses indicate anadromy, suggesting that salmon runs were established by at least the terminal Pleistocene. The early use of this resource has important implications for Paleoindian land use, economy, and expansions into northwest North America.

The Beginnings of the Internationalization of the Cod Fish Trade in London

London's international fish trade can be traced back 800 years to the medieval period, according to new research published today in the journal Antiquity.

The research, led by archaeologists from UCL, Cambridge and UCLan, provides new insight into the medieval fish trade and the globalisation of London's food supply.

Archaeologists analysed data from nearly 3,000 cod bones found in 95 different excavations in and around London. They identified a sudden change in the origin of the fish during the early 13th century, indicating the onset of a large-scale import trade.

Lead author Dr David Orton, UCL Institute of Archaeology, said: "It's a truly remarkable shift. We had expected a gradual increase in imports as demand grew along with the city's medieval population – thought to have quadrupled between AD 1100 and AD 1300 – but this is something else: evidence for locally caught cod drops off suddenly when the imports come in.

"What did this mean for the local fishing industry? Until we've looked at other fish species and other towns we can't be sure, but the start of this long-range trade may well be an important message about changes in supply and demand."

Cod were traditionally decapitated as part of preservation for long-range transport, meaning the researchers knew that head bones found during excavations must represent fresh fish from relatively local waters.

Vertebrae, by contrast, might be either local or imported.

Comparing frequencies of the two over time, the researchers discovered the sudden switch 'from heads to tails' during the early 13th century. To confirm that the vertebrae were from distant waters, the team used biochemical signatures to match some of the individual bones to their most likely sources, with the results supporting the archaeological data perfectly: from the middle of the 13th century, the majority of sampled bones have signatures suggesting an origin in the far north, probably Arctic Norway.

China Declares New Restrictions on Fishing in South China Sea

The United States, already at odds with China over that country's air defense zone, said on Thursday that new Chinese fishing restrictions in disputed waters in the South China Sea were "provocative and potentially dangerous."

The legislature of China's Hainan province approved rules in November that took effect on January 1 requiring foreign fishing vessels to obtain approval to enter waters under its jurisdiction.

Such a move, if broadly enforced, could worsen tensions in the region. Beijing claims almost the entire oil- and gas-rich South China Sea, rejecting rival claims to parts of it from the Philippines, Taiwan, Malaysia, Brunei and Vietnam.

"The passing of these restrictions on other countries' fishing activities in disputed portions of the South China Sea is a provocative and potentially dangerous act," State Department spokeswoman Jen Psaki told a news briefing.

"China has not offered any explanation or basis under international law for these extensive maritime claims."

"Our long-standing position has been that all concerned parties should avoid any unilateral action that raises tensions and undermines the prospects for a diplomatic or other peaceful resolution of differences."

The fishing rules followed China's creation of an air defense identification zone in late November above the East China Sea in an area that includes islands at the heart of a bitter territorial dispute with Japan.
