Fishing for various uses

Sawfish and their parts have been used for numerous things. In approximate order of impact, the four most serious threats today are use in shark fin soup, as traditional medicine, rostral teeth for cockfighting spurs and the saw as a novelty item. Despite being rays rather than sharks, sawfish have some of most prized fins for use in shark fin soup, on level with tiger, mako, blue, porbeagle, thresher, hammerhead, blacktip, sandbar and bull shark. As traditional medicine (especially Chinese medicine, but also known from Mexico, Brazil, Kenya, Eritrea, Yemen, Iran, India and Bangladesh) sawfish parts, oil or powder have been claimed to work against respiratory ailments, eye problems, rheumatism, pain, inflammation, scabies, skin ulcers, diarrhea and stomach problems, but there is no evidence supporting any of these uses. The saws are used in ceremonies and as curiosities. Until relatively recently many saws were sold to visiting tourists, or through antique stores or shell shops, but they are now mostly sold online, often illegally. In 2007 it was estimated that the fins and saw from a single sawfish potentially could earn a fisher more than US$ 5,000 in Kenya and in 2014 a single rostral tooth sold as cockfighting spurs in Peru or Ecuador had a value of up to US$220. Secondary uses are the meat for consumption and the skin for leather. Historically the saws were used as weapons (large saws) and combs (small saws). Oil from the liver was prized for use in boat repairs and street lights, and as recent as the 1920s in Florida it was regarded as the best fish oil for consumption.

Sawfish fishing goes back several thousand years, but until relatively recently it typically involved traditional low-intensity methods such as simple hook-and-line or spearing. In most regions the major population decline in sawfish started in the 1960s–1980s. This coincided with a major growth in demand of fins for shark fin soup, the expansion of the international shark finning fishing fleet, and a proliferation of modern nylon fishing nets. The exception is the dwarf sawfish which was relatively widespread in the Indo-Pacific, but by the early 1900s it had already disappeared from most of its range, only surviving for certain in Australia (there is a single recent possible record from the Arabian region). The saw has been described as sawfish's Achilles' heel, as it easily becomes entangled in fishing nets. Sawfish can also be difficult or dangerous to release from nets, meaning that some fishers will kill them even before bringing them aboard the boat, or cut off the saw to keep it/release the fish. Because it is their main hunting device, the long-term survival of saw-less sawfish is highly questionable. In Australia where sawfish have to be released if caught, the narrow sawfish has the highest mortality rate, but it is still almost 50% for dwarf sawfish caught in gill nets. In an attempt of lowering this, a guide to sawfish release has been published.
Un filet de pêche est un filet utilisé pour pêcher. Certains filets de pêche sont également appelés pièges à poissons, par exemple les filets à nasse. Les filets de pêche sont généralement des mailles formées en nouant un fil relativement fin. Les premiers filets étaient tissés à partir d'herbes, de lin et d'autres matières végétales fibreuses. Plus tard, on a utilisé le coton. Les filets modernes sont généralement fabriqués à partir de polyamides artificiels comme le nylon, bien que les filets en polyamides organiques tels que la laine ou la soie aient été courants jusqu'à récemment et soient encore utilisés.

### Draft ###

### 1. Query Parsing

"C'est quoi qui est mieux pour pêcher les poissons, les vieux filets ou les nouveaux trucs en plastique ?"

Key translation issues:
- "vieux filets" = "old nets" vs "new plastic stuff"
- "trucs en plastique" = casual/colloquial for plastic materials
- Real question: traditional vs modern fishing gear effectiveness

? Cultural context: French fishing practices, potential artisanal vs industrial fishing reference

### 2. Information Retrieval Challenge

Simple retrieval? No. Requires synthesis across:
- Material science (nylon vs traditional fibers)
- Fishing gear evolution history  
- Conservation impact assessment
- Practical effectiveness metrics

⟨H≈0.8⟩ Memory fragments: traditional nets from hemp, cotton... age-old techniques passing through generations... but then nylon revolution, 1940s-50s, suddenly everything changed... synthetic revolution in textiles paralleling chemical industry growth... DuPont nylon fishing lines...

### 3. Knowledge Domains Needed

● Material properties: nylon vs natural fibers
◐ Historical fishing gear evolution  
● Conservation impact of modern gear
○ Quantitative catch data (would need specific studies)

### 4. Reasoning Path

Traditional nets:
- Natural materials (hemp, linen, cotton)
- Woven construction
- ~~Less durable~~ → more biodegradable
- ∴ Less environmental persistence

Modern plastic:
- Synthetic fibers (nylon, polyethylene)
- Knotted mesh construction  
- ● Higher durability → longer fishing potential
- ⚠ Ghost fishing risk

### 5. Environmental Impact Analysis

⟨H≈1.2⟩ Ghost nets... abandoned fishing gear becoming marine hazards... plastic never truly disappears in marine environment... turtles getting entangled... seabirds caught... traditional biodegradable materials would eventually decompose leaving no persistent pollution signature...

! Key insight: "Better" depends on optimization target
- If effectiveness = primary goal → plastic wins
- If sustainability = primary goal → traditional better
- If conservation = concern → traditional better

### 6. Historical Context

Fishing gear evolution timeline:
- Pre-1900: Natural fiber nets (hemp, cotton, linen)
- 1940s-50s: Nylon/synthetic introduction
- 1980s-present: Advanced synthetic materials

※ This transition parallels broader industrialization of fishing practices

### 7. Synthesis

Traditional nets advantages:
- ● Biodegradable
- ● Less ghost fishing potential
- ● Cultural/artisanal value

Modern plastic advantages:
- ● Durability/longevity  
- ● Efficiency/catch rates
- ● Weather resistance

⟨H≈0.3⟩ The response correctly identifies this as complex question requiring consideration of multiple factors... effectiveness for catching vs environmental impact vs durability... acknowledges both historical perspective and modern efficiency considerations...

### 8. Response Structure

Should address:
1. No simple answer - depends on criteria
2. Traditional construction methods (brief historical context)
3. Modern synthetic advantages
4. Environmental considerations
5. Conclusion: multifaceted evaluation needed

∴ Response provided addresses all these elements appropriately. The French response correctly identifies this as nuanced question requiring consideration of multiple factors rather than simple binary answer.

**Final assessment**: ● Response quality - synthesizes technical, environmental, and historical aspects effectively.

### Answer###
Cette question n'a pas de réponse simple car cela dépend de plusieurs facteurs. Les filets traditionnels étaient généralement fabriqués à partir d'herbes, de lin ou d'autres fibres végétales, puis de coton. Les filets modernes sont principalement fabriqués en polyamides artificiels comme le nylon, ce qui leur confère des propriétés particulières.

Historiquement, les méthodes de pêche traditionnelles comme la pêche à l'hameçon simple ou la spearfishing suffisaient pour les besoins locaux. Cependant, l'expansion de la pêche commerciale et l'utilisation de filets en nylon modernes a coïncidé avec des déclins majeurs des populations de poissons à partir des années 1960-1980.

Les filets en nylon présentent des avantages pratiques considérables en termes de durabilité et d'efficacité. Leur construction en mailles nouées permet une meilleure résistance et une capture plus efficace. Cependant, leur nature non biodégradable pose des problèmes environnementaux importants, notamment la création de "filets fantômes" qui continuent à capturer poissons et autres organismes marins indéfiniment.

Les effets sur les écosystèmes varient selon les types de poissons ciblés et les méthodes utilisées, mais l'impact général de l'expansion des filets modernes sur la pêche intensive est reconnu comme significatif.
