The Status Quo of the Criminal Accountability for Marine Illegal Fishing in China: From the Perspective of Judgment Analysis

Over the past few years, China’s marine economy has been vigorously booming, while strong measures have been equally undertaken to ensure superior quality of the marine environment. However, the country is still suffering illegal fishing problems, which hinder the marine ecological environment and fishery resources from reaching sustainable development both internally and globally. To this end, the Chinese government has ratified a series of legal documents to provide the basis for judicial departments to hold individuals and groups responsible for practicing illegal fishing at sea. Although the measures have indeed performed well in some instances, a number of legal obstacles remain to be fixed. In this article, to realize the status quo of the control of maritime illegal fishing in China, all the criminal judgments relevant to illegal fishing at sea from 2014 were collected and analyzed not only qualitatively but also quantitatively, through which the existing problems of accountability for illegal fishing at sea in China were summarized. In addition, a number of related studies were examined and in-depth interviews were organized to clarify the main reasons for these problems and propose some necessary solutions. It is believed that our findings would not only help to improve the control of maritime illegal fishing and boost the marine ecological environment protection in China, but also to establish a possible reference for other countries in the world.

On the basis of the length of marine space planning, the planning objective function is constructed. Based on the theory of planning behavior and the introduction of ethics variables, this paper constructs the leisure tourism marine space planning model from the perspective of TPB, which determines the types and contents of leisure tourism marine space planning. The results show that the method is efficient and in line with the actual planning environment.

Extension Evaluation of Marine Ecological Carrying Capacity: An Empirical Study Based on the Development of Tropical Marine Island Free Trade Ports in Developing Countries

Today, the global economy presents a leaping economic network centered on coastal areas. Relying on the ocean has become a very important economic development path for many countries and regions. To coordinate and solve the contradiction between the economic development of Hainan Island and the protection of marine ecological environment, this study, based on the matter-element extension evaluation model, examines the marine ecology of Hainan Island considering the construction of a free trade port. This study uses the extension set theory to describe the advantages of the intermediate state and dynamic trend of the transformation of the assessment object to a certain level, to improve the assessment accuracy of marine ecological carrying capacity. The results show that the marine ecological carrying capacity of Hainan Island in 2016 to 2018 is relatively stable, at the transformation grade of N3, indicating that the marine ecology of Hainan Island is in a medium bearing, sub health state. Focusing on protecting marine ecology, developing a modern service industry, and developing high-tech industry can be effective in improving the ecological carrying capacity of Hainan Island.

A Microfluidic Prototype System towards Microalgae Cell Separation, Treatment and Viability Characterization.

There are a huge number, and abundant types, of microalgae in the ocean; and most of them have various values in many fields, such as food, medicine, energy, feed, etc. Therefore, how to identify and separation of microalgae cells quickly and effectively is a prerequisite for the microalgae research and utilization. Herein, we propose a microfluidic system that comprised microalgae cell separation, treatment and viability characterization. Specifically, the microfluidic separation function is based on the principle of deterministic lateral displacement (DLD), which can separate various microalgae species rapidly by their different sizes. Moreover, a concentration gradient generator is designed in this system to automatically produce gradient concentrations of chemical reagents to optimize the chemical treatment of samples. Finally, a single photon counter was used to evaluate the viability of treated microalgae based on laser-induced fluorescence from the intracellular chlorophyll of microalgae. To the best of our knowledge, this is the first laboratory prototype system combining DLD separation, concentration gradient generator and chlorophyll fluorescence detection technology for fast analysis and treatment of microalgae using marine samples. This study may inspire other novel applications of micro-analytical devices for utilization of microalgae resources, marine ecological environment protection and ship ballast water management.
