Abstract

One of the determining variables that influences coral growth morphology is the aquatic environment. Reef corals are unusual organisms with plant-like development patterns. Reef growth is influenced greatly by the aquatic environment, particularly hydro-oceanography. The same type of coral can have different morphological forms. This mismatch in form can lead to type identification mistakes. There is still a lack of research on morphological changes as an impact of coral plasticity in responding to environmental variables. The goal of this work is to compile a bibliography of coral morphological plasticity studies. Publish or Perish (PoP) program locates the Scopus database and processes the articles. After screening, 101 of the 138 articles found in the Scopus database are eligible to be found. Mendeley reference manager software is then used to handle the selected references. After maintaining the database, use VOSviewer software to classify and visualize the data. The findings suggest that the research topic was chosen based on keywords. Coral morphological plasticity research is primarily focused on the terms coral colonies and species. Small-scale coral morphology, morphological variability, and coral morphometrics are among the topics that have received little attention. The possibility of conducting research on the three subjects is still open. There are still many unanswered mysteries about coral. This work is crucial to research since it illustrates the direction of future plans for exposed coral morphology and plasticity. This review serves as a useful starting point for future coral morphology and plasticity research.

Abstract

Blue swimming crab (BSC) is a fishery commodity with high economic value and great demand in domestic and foreign markets. P. pelagicus swimming crabs are commonly found in Indonesian sea waters, one of the largest contributors to the country's foreign exchange after shrimp and tuna. The high demand for blue crab resources will trigger an increase in fishing efforts. If this is done continuously, it is feared that it could endanger the population structure. Moreover, disrupting the sustainability of blue swimming crab resources in the waters, this study examines the morphometric distribution and growth pattern of P. pelagicus crabs based on environmental characteristics in Candi waters, Pamekasaan Regency. Census sampling was carried out using the census method; the census method was carried out by taking all crab samples caught by fishermen. The results obtained found 33 individual crabs, which were divided into three classes, namely small (<10 cm), medium (>10 cm), and large (>12 cm) size classes. Male crabs dominated the research locations with wider straps than female crabs. The analysis results show that the width-weight relationship's b values are 1.47 (males) and 2.00 (females). In addition, male and female crabs have a positive allometric growth pattern. Blue swimming crabs are often found in habitats with a substrate of dusty mud, high salinity and organic matter.
