# Analysis on the control of the black tiger shrimp in the America from the perspective of international cooperation

## TL;DR

This paper explores how international cooperation can help control the invasive black tiger shrimp in America to balance ecological security and economic benefits.

## Contribution

The study introduces differential game models to analyze the effectiveness of various control strategies for black tiger shrimp.

## Key findings

- Higher prices for feed and shrimp increase the degree of control over black tiger shrimp.
- The U.S. benefits more from feed production when shrimp prices and its control reputation are low.
- Cooperative countries prefer using natural enemies to control shrimp over other methods.

## Abstract

The invasive black tiger shrimp has caused serious ecological problems in the America. However, since it can be directly eaten or made into feed, it may be beneficial to other countries. In order to ensure ecological security, it is necessary to control the invasion of the black tiger shrimp through international cooperation. Common control modes of the black tiger shrimp include the introducing natural enemy mode, making feed mode and the "bringing to the table" mode. In order to derive the applicable scope of various control modes of the black tiger shrimp and provide suggestions for the security and sustainability of the ecological supply chain of the America and cooperative country, this article constructs three differential game models and compares and analyzes the equilibrium results obtained by the models. Finally, the study shows that the higher the price of feed and the price of black tiger shrimp, the greater the degree of control of the black tiger shrimp. If the price of the black tiger shrimp and the reputation of the America for controlling the black tiger shrimp are lower, the America can gain more benefits under the feed production mode. Otherwise, the America prefers to sell the black tiger shrimp directly, thus directly "bringing to the table". Compared with the feed production or "bringing to the table" mode, cooperative country prefer to control the black tiger shrimp flooding through the natural enemy introduction mode.
