Abstract:
Background: Understanding the relationship between body length and weight in
commercially essential shrimp species is crucial for assessing growth patterns and
estimating biomass. This study aims to evaluate the relationship between body length
and weight in three species of shrimp, namely the whiteleg shrimp ( Penaeus merguensis
), whiteleg shrimp (Litopenaeus vannamei), and tiger shrimp (Penaeus monodon), as a
basis for fisheries management in the waters of Jaloh Island, Batam City.
Methodology: The samples were collected randomly from the results, catching
fishermen at three stations during a day of data collection. Morphometric
measurements were conducted on 180 animal shrimp, namely whiteleg shrimp
(Penaeus merguensis). ( Panaeus merguensis ) , white shrimp ( Litopanaeus vannamei ), and
tiger shrimp ( Panaeus monodon ) . The relationship has been analyzed for a long time
using simple regression using Excel software. The connection between character
morphometrics and total length was analyzed with ANCOVA using SPSS 27 software.
Findings: The results showed the determinant coefficient of the three species of shrimp
in this study indicates a very close relationship between the growth of length and
weight of shrimp. In the P. monodon species, it is known that approximately 78 % of
the weight gain is attributed to the increase in shrimp length, while 22 % is attributed
to other factors. Characters that influence the total length of the three species are
generally overall, where P. merguensis is more influenced by the tail and weight, L.
vannamei by the front, back, and body mass, while P. monodon involves almost all parts
of the body. Contribution: This approach helps estimate biomass, identify
morphological variations between species, and provides a scientific basis in supporting
efforts to manage shrimp resources sustainably.
