Abstract

Green Tiger Prawn is one of the Prawn from the Penaeidea family and is one the catches caught in the waters of Samboja. This research conducted in October-December 2021 in the waters of Samboja, Kutai Kartanegara catching prawn at night using trawls. The sample used was 129 green tiger prawn with 90 females and 39 males. This study aims to determine the location of quartiles, deciles and persentiles in prawn data assisted by microsoft Excel software and presented in the form of histogram. The results of this study found that the location of the Q1 quartile was 25%, Q2 was 50% and Q3 was 75%. Decile D1 is 10%, D2 is 20% and D3 is 30%. Percentile P25 is 25%, P50 is 50%, dan P90 is 90%.

Abstract

Southern Velvet Shrimp (Metapenaeopsis palmensis) of the Penaeidae family, morphometric measurements were carried out to see things that affect the shape of the species. This study was aimed to provide information about the morphometric study of red rice shrimp (Metapenaeopsis palmensis) caught at night in Samboja waters, Kutai Kartanegara. This research was conducted in October-November 2021, the sample used was 300 brown rice shrimp (Metapenaeopsis palmensis). The morphometric study used covariance analysis to look at 20 morphometric covariates that affect the total length (PTO). Based on the results of univariate anova test analysis, it is known that 20 morphometrics have a sig <0.05, which means that H1 is accepted, which means it has an effect on PTO. Furthermore, ancova analysis was carried out, 13 morphometric results were obtained which had sig <0.05 for PTO, namely rostrum length (RST), head length (PK), first segment length (PRP), second segment length (PRD), third segment length ( PRT), fourth segment length (PRE), fifth segment length (PRL), sixth segment length (PRN), headless length (PTK), telson length (TLN), carapace button length (PKB), third lower segment length (PTB) ), and the length of the fifth lower segment (PLB).
