Marine Living Resources

Industrial Application of Fish Cartilage Tissues

Cartilage is primarily composed of proteoglycans and collagen. Bioactive compounds derived from animal cartilage, such as chondroitin sulfate and type II collagen, possess multiple bioactivity and are incorporated into popular health products. This review article considers the potential of alternative sources of fish cartilage for industrialization. Three key points, such as sustainable fish production, the new fish processing model, and market demand, were taken into account for the future efficient use of fish cartilage. The industrialization of fish-derived cartilage products is beneficial for achieving the sustainable development of the economy and local societies.

Treatment of Secondary Urban Wastewater Using a Low-Ammonia Tolerance Marine Microalgae via Zeolite-Based Adsorption

The low tolerance of marine microalgae to ammonia and hyposalinity limits their use in the treatment of urban wastewater (URW). In this study, using the marine microalga *Amphidinium carterae*, it is demonstrated for the first time that this obstacle can be overcome by introducing a zeolite-based adsorption step to obtain a tolerable URW flow. The maximum ammonia adsorption capacities measured in the natural zeolite used are among the highest reported. The microalga grows satisfactorily in zeolite-treated URW and seawater mixtures in a wide range of ratios, with and without salinity adjustment, provided the ammonium concentration is below the limit tolerated by the microalga (6.3 mg L).

Marine Biotechnology

Fish scales as a biotechnological application in nanomaterials

The synthesis technique employed is environmentally friendly and offers a simple way to convert fish waste into materials of infinitely greater utility. The nanomaterial is obtained without resorting to harsh experimental conditions, high-cost carbon sources, or additional hazardous catalysts. In short, it is a super easy synthesis and a new technique for producing green and sustainable functional nanomaterials.”

Non-destructive sampling device

The non-destructive sampling device according to the present invention comprises: a syringe with two or more agneedles; a guide directing the movement of the syringe and a needle restoring means attached to the lower end of the guide and transmitting an elastic restoring force to the syringe. Consequently, the non-destructive sampling device allows anyone, including an unqualified person, to easily collect a sample for risk analysis of a fishery product and can maintain the quality of the fishery product without affecting its shelf life.

Farmed Fish Tracking and Verification System

A farmed fish tracking and verification system involves introducing biomarkers into a batch of farmed fish and storing biomarker information in a database. Other data is also stored, such as production information and funding information. Funding information may include data on funders who contributed funds to the production of the fish. Funding information may also include payment instructions to funders. After the fish is processed and the product is delivered to a customer, the product can be checked for biomarker information for approval. The database can then be consulted using the biomarker information to track and verify information about the fish. Once the fish product is approved and sold to a customer, a portion of the revenue can be transferred directly to one or more funder accounts based on payment instructions. In some embodiments, the database stores information related to aquaculture fish on the blockchain, so that this data can also be tracked and verified. Customized fish production techniques based on the unique needs of an individual or group of people are also disclosed.

Method for Producing Agarotriose Derived from Seaweed and its Use as a Prebiotic

The present invention relates to a method for producing agarotriose derived from seaweed and its use as a prebiotic. More specifically, the present invention investigates the characteristics of agarotriose as a prebiotic that is selectively metabolized by probiotic microorganisms, thus allowing agarotriose to be used as an anticancer or anti-inflammatory agent in the food and pharmaceutical industries, and allowing agarotriose to be obtained in high yield through efficient purification with minimal loss, after enzymatic hydrolysis of a polysaccharide derived from red algae without pretreatment.
