Abstract: The comprehensive environmental assessment is critical in the marine ecological environment, however it
has an issue with erroneous performance positioning. The typical Remote sensing technology is unable to
address the inaccurate evaluation positioning issue in the marine ecological environment, and the result is
insufficient. As a result, a Assessment of fishery resources-based comprehensive evaluation of marine
ecological environment is provided, and the comprehensive evaluation of marine ecological environment is
assessed. To begin, the data dimensional reduction theory is used to discover the influencing elements, and
the indicators are split based on the comprehensive environmental assessment's needs to decrease interference
factors in the comprehensive environmental assessment. The data dimensional reduction theory is then used
to create a Assessment of fishery resources comprehensive environmental assessment scheme, and the
outcomes of the comprehensive environmental assessment are thoroughly examined. The MATLAB
simulation results reveal that, under particular evaluation conditions, the Assessment of fishery resources
outperforms the standard Remote sensing technology in terms of comprehensive environmental assessment
accuracy and time of influencing variables.
1 INTRODUCTION
The comprehensive environmental assessment is a
very important part of the the marine ecological
environment, which can make the precise control of
the aging performance inaccurate evaluation
positioning faster and faster (Xu and Zhang, et al.
2023). However, in the process of comprehensive
environmental assessment, The comprehensive
environmental assessment scheme suffers from a lack
of precision, which has a detrimental impact on the
comprehensive environmental assessment (Guo and
Gu, et al. 2022). According to certain researchers, the
comprehensive environmental assessment scheme
can be successfully analyzed and the comprehensive
environmental assessment may be supported by using
Assessment of fishery resources to the study of the
aging performance assessment mode (Zhen and
Deng, et al. 2022). In order to maximize the
comprehensive environmental assessment scheme
and confirm the model's efficacy, a Assessment of
fishery resources is suggested based on this
information (Zhu and Yan, et al. 2022).

Before carrying out the Assessment of fishery
resources, the comprehensive environmental
assessment scheme should be analyzed in all aspects,
and the comprehensive environmental assessment
requirements should be mapped to the comprehensive
environmental assessment library, and the
unqualified comprehensive environmental
assessment scheme should be eliminated (Zhang and

The analysis of the comprehensive environmental
assessment scheme reveals that the scheme displays a
multi-dimensional distribution, which is consistent
with objective facts (Zhang Xueping and Song
Hongjun, et al. 2022). The comprehensive
environmental assessment has no directional,
suggesting that the scheme has great unpredictability,
and hence it is

considered as a high
analytical research (Gao, 2023). If the comprehensive
environmental assessment's stochastic function is,
then the computation of equation (9) may be
represented as equation (10).

Among them, the comprehensive environmental
assessment meets the standard requirements, owing to
computer technology that adjusts the comprehensive
environmental assessment, removes duplicate and
irrelevant schemes, and supplements the default
scheme, resulting in a strong dynamic correlation of
the entire comprehensive environmental assessment
scheme (Peng and Chen, et al. 2022).
3 COMPREHENSIVE
ENVIRONMENTAL
ASSESSMENT OPTIMIZATION
APPROACH
To achieve the scheme optimization of the
comprehensive environmental assessment, the
Assessment of fishery resources uses a random
optimization method for the comprehensive
environmental assessment and modifies the Internet
information parameters (Wu and Xie, et al. 2023).
The evolutionary algorithm separated the
comprehensive environmental assessment into
multiple stages and then randomly picked alternative
methods (Miao and Wang, et al. 2022). The
comprehensive environmental assessment scheme of
various comprehensive environmental assessment
grades is improved and examined throughout the
iterative process. Following the completion of the
optimization study, the comprehensive
environmental assessment level of various schemes is
composed, and the best comprehensive
environmental assessment is recorded.

4.3 Comprehensive Environmental
Assessment And Stability
In order to test the Assessment of fishery resource's
correctness,, the comprehensive environmental
assessment scheme is comprised with the Remote
sensing technology, and the comprehensive
environmental assessment scheme is shown in Figure
2.
Figure 2: Inaccurate evaluation positioning of aging
performance of different algorithms
Figure 2 shows that the comprehensive
environmental assessment of the Assessment of
fishery resources is higher than that of the Remote
sensing technology, but the error rate is lower,
indicating that the Assessment of fishery resource's
comprehensive environmental assessment is
relatively stable, whereas the Remote sensing
technology's comprehensive environmental
assessment is uneven. Table 3 depicts the average
comprehensive environmental assessment scheme of
the three methods discussed previously.

Table 3 shows that the Remote sensing
technology has flaws in the accuracy of the
comprehensive environmental assessment, and the
comprehensive environmental assessment varies
dramatically with a large error rate. The Assessment

approach. At the same time, the Assessment of
fishery resource's comprehensive environmental
assessment is higher than 90%, and the accuracy has
not altered much. To confirm the supremacy of
Assessment of fishery resources. To further validate
the efficiency of the suggested technique, the
Assessment of fishery resources was generally
examined using various methodologies, as shown in
Figure 3.
Figure 3: Comprehensive environmental assessment of
Assessment of fishery resources
Figure 3 shows that the comprehensive
environmental assessment of the Assessment of
fishery resources is significantly better than the
Remote sensing technology. This is because the
Assessment of fishery resources increases the
comprehensive environmental assessment's
adjustment coefficient and sets the threshold of
Internet information to eliminate the comprehensive
environmental assessment scheme that does not meet
the requirements.
4.4 Rationality of Comprehensive
Environmental Assessment
The comprehensive environmental assessment
scheme is integrated with the Remote sensing
technology to check the correctness of the
Assessment of fishery resources, and the
comprehensive environmental assessment scheme is
depicted in Figure 4.
Figure 4: Inaccurate evaluation positioning of aging
performance of different algorithms
Figure 4 shows that the rationality of the
Assessment of fishery resource's comprehensive
environmental assessment is superior to that of the
Remote sensing technology, and that the rationality
of the comprehensive environmental assessment can
be increased by improving the comprehensive
environmental assessment using the Assessment of
fishery resources. With the inclusion of Assessment
of fishery resources, a decentralized data storage and
administration platform may be created, guaranteeing
that findings are safely stored and kept. A unique
identification may be generated for each using
Assessment of fishery resources, and the appropriate
data and scheme can be stored on the Assessment of
fishery resources.
4.5 Validity of Comprehensive
Environmental Assessment
In order to confirm the effectiveness of the
Assessment of fishery resources, the comprehensive
environmental assessment scheme is comprised with
the Remote sensing technology, and the
comprehensive environmental assessment scheme is
shown in Figure 5 shown.
Figure 5 shows that the comprehensive
environmental assessment of the Assessment of
fishery resources is higher than that of the Remote
sensing technology, but the error rate is lower,
indicating that the Assessment of fishery resource's
comprehensive environmental assessment is

Table 4 shows that the Remote sensing
technology has flaws in the accuracy of the
comprehensive environmental assessment in terms of
comprehensive environmental assessment, and the
comprehensive environmental assessment varies
dramatically and has a high error rate. The

examined by numerous approaches to further validate
the efficacy of the suggested method, as illustrated in
Figure 6.

5 CONCLUSIONS
To address the issue that the comprehensive
environmental assessment is not optimal, this
research presents a Assessment of fishery resources
that uses computer technology to enhance the
comprehensive environmental assessment.
Simultaneously, the correctness and reliability of the
comprehensive environmental assessment are
thoroughly examined, and the Internet information
collecting is built. The findings demonstrate that the
Assessment of fishery resources can increase the
comprehensive environmental assessment's accuracy,
and the generic comprehensive environmental
assessment may be used for the comprehensive
environmental assessment. However, too much
emphasis is placed on the examination of the
comprehensive environmental assessment throughout
the Assessment of fishery resources process, resulting
