Study of the Behavioral Characteristics of Lutjanus erythropterus on the Basis of the Distance and Structure of Artificial Reefs
Manju Jiang, Yu Guo, Chuanxin Qin, Jia Zhang, Ankai Zhang

TL;DR
This study examines how different distances and structures of artificial reefs affect the behavior of juvenile Lutjanus erythropterus, offering insights for better reef design and marine conservation.
Contribution
The study identifies optimal reef spacing and preferred reef types for juvenile Lutjanus erythropterus, contributing to improved artificial reef design.
Findings
Juvenile Lutjanus erythropterus showed significant attraction to reefs when spaced at 0.5 L.
Cubic artificial reefs were the most preferred by the fish, with the strongest reefing behavior observed.
Reefs spaced at 2.5 L or 3.0 L had independent effects, while closer reefs showed combined effects.
Abstract
With the further study of marine ecological protection and sustainable fishery development, artificial reefs, an effective means of marine ecological engineering, have gradually become the focus of research. Artificial reefs can not only provide marine organisms with habitats and breeding and foraging sites but also help promote the recovery and stabilization of marine ecosystems and increase their production. In this study, Lutjanus erythropterus was used as a target to analyze aggregation behavior comprehensively under different reef spacings and behavioral responses in the presence of many different types of reefs simultaneously. This study helps to understand the ecological needs of juvenile L. erythropterus more accurately, provides a scientific basis for optimizing the design and layout of artificial reefs, has a positive impact on the protection and proliferation of reef fish…
