Although the expansion of the leather goods market is positive for the global economy, it raises concerns from environmental and ethical perspectives.

Leather production often involves processes that can harm nature and raise questions about animal welfare. Specifically, the tanning process, which turns hides into durable leather by preserving them and stopping decomposition, relies heavily on chromium, posing significant environmental challenges. Chromium compounds can harm aquatic life and disrupt ecosystems when released into water bodies. 

Furthermore, there are health risks for workers and those who live near tanneries, who may be exposed to toxic substances without adequate safety measures. One study revealed that increased risks for several cancers had been reported among tannery workers, including lung cancer, pancreatic cancer, skin cancer and melanoma, kidney cancer, pancreatic cancer, buccal cavity and pharynx cancers, bladder cancer, and sinonasal cancer. 

Moreover, raising animals for leather demands vast amounts of water and extensive areas of pastureland. This requirement strains water resources and leads to deforestation and habitat loss as land is cleared to accommodate livestock. 

In fact, since the 1960s, there has been a dramatic increase in the number of cattle in the Amazon Basin, growing from 5 million to between 70 and 80 million. This explosion in cattle population has led to significant environmental consequences; approximately 15% of the Amazon forest has been cleared, with about 80% of these deforested areas, roughly 900,000 square kilometers, being converted into pastureland.

Origin

Fish leather, also called piscine or fish skin leather, is an innovative and sustainable material created from the skins of fish, which are typically by-products of the seafood industry. Rather than discarding these skins, they are processed and transformed into durable, flexible, and visually striking leather. 

The practice of making fish leather is not new. It boasts a rich historical legacy deeply embedded in the traditions of Indigenous craftsmanship. Long before the advent of synthetic materials, communities from coastal and riverine areas globally harnessed fish skins’ strength and water-resistant properties. This material was not just a resource; it was vital for survival.

As highlighted by Hakai Magazine, various cultures have creatively adapted fish leather to meet their needs. In Japan, the Ainu people transformed salmon skins into durable boots fastened with rope. The Hezhen and Nivkh peoples along the Amur River in northeastern China and Siberia crafted the material into coats and thread, essential for withstanding harsh climates. In the farther north of Canada, the Inuit utilized fish leather to create protective clothing. Similarly, the Alutiiq, Athabascan, and Yup’ik communities made boots, mittens, containers, and parkas out of fish skins in Alaska.

A particularly striking use of fish leather was by the Yup’ik people, who designed qasperrluk—hooded fish skin parkas crucial for winter survival. These garments were ingeniously designed to double as emergency shelters. In times of need, a man could prop up the hood with an ice pick and secure the edges to form a tent-like structure, showcasing the material’s versatility and life-saving qualities.

Species

Fish leather is crafted from various fish species, with salmon and perch frequently chosen due to their suitable properties and availability. However, the scope of materials extends beyond these two, incorporating other fish like cod, tilapia, catfish, and even the luxurious sturgeon. 

The factors influencing this choice include the fish’s availability in certain regions, making it easier to source and more sustainable to use. Sustainability is a critical aspect, as it ensures that the production of fish leather contributes positively to the environment by minimizing waste and not depleting fish populations.

Additionally, different species provide unique textures and colors to the leather produced. For instance, salmon skin might offer a more subtle texture and color palette, while sturgeon can result in a more distinguished pattern akin to traditional exotic leathers. This diversity allows for a wide range of applications and aesthetics in products made from fish leather, catering to various tastes and design requirements. 

Production

Producing fish skin leather is notably more environmentally friendly than the traditional methods of creating conventional leather. This gentler approach encompasses less aggressive chemicals and uses fewer resources, aligning with efforts to minimize environmental impact. 

Although the specific techniques employed by the limited number of tanneries specializing in fish leather remain closely guarded secrets, the general methodology is known to be more eco-friendly. 

Typically, the process begins with soaking the fish skins in a specialized concoction of natural and less harmful substances. This soaking period is crucial for eliminating the skins’ inherent fishy odors and oils. From there, the skins are dried and tanned using eco-friendly tanning agents, preserving and strengthening them for transformation into leather. 

Once tanned, the fish leather can be dyed in various colors, offering a wide range of aesthetic options. This is followed by a finishing process, where the leather might be coated to enhance its durability and waterproofness or to add a glossy or matte finish, depending on the desired outcome.

The final steps involve conditioning to ensure the leather remains supple and softening treatments to enhance its tactile qualities. These processes are essential for ensuring the fish leather looks exquisite and feels luxurious.

Fish Leather vs. Traditional Leather

When comparing fish leather to traditional leather, several vital differences emerge, chiefly regarding their environmental impact, production process, durability, texture, and applications.
