Abstract

Yellow Shrimp (M. brevicornis) is a type of shrimp caught by Samboja fishermen which has a fairly high economic value. This study aims to provide information about the morphomorphological study of Yellow Shrimp (M. brevicornis) caught in the waters of Samboja, Kutai Kartanegara. This research was conducted in the waters of Samboja, Kutai Kartanegara, in November-December 2021, the sample used was 300 Yellow Shrimp (M. brevicornis). Morphometric study onmorphometric study Yellow Shrimp (M. brevicornis) using analysis with analysis of covariance test (ANCOVA) to see 20 morphometric covariates that affect total length (PTO). Based on the results of the analysis of the univariate ANOVA test, it is known that 20 morphometrics have a sig value <0.05, which means that H1 is accepted, that all morphometrics have an effect on PTO. Furthermore, ancova analysis was performed, obtained 5 morphometrics that have sig < 0.05, namely head length (PK), first segment length (PRP), telson length (TLS), lower head length (PKB) and tail length (PE), so from the results of the ancova test analysis showed that the most significant morphometric effect on PTO was 5 morphometers.

Abstract

The high sedimentation and erosion in reservoirs in Indonesia have been the main factors causing the decrease in reservoir capacity. High sedimentation is the main factor causing the decline in the carrying capacity of the reservoir ecosystem. This research was conducted to determine the production of dissolved oxygen and respiration in the upper and lower zones of the sechi disk in the Benanga Reservoir. As data on dissolved oxygen production and respiration in the upper and lower zones of the secchi disk. This study uses a dark and light bottle storage method to see the difference between the upper and lower zones of the waters so as to get the production and oxygen consumption. Dissolved oxygen production and consumption studies (dark and light bottles) used a 4-hour incubation. The results show that the dissolved oxygen consumption in the upper zone is 2.07 mg/L and the lower zone is 1.90 mg/L, gross primary productivity (GPP) in the upper zone is 4.95 mg/L and the lower zone is 4.32 mg/L, and the net primary productivity (NPP) is in the upper zone. 2.88 mg/L and lower zone 2.42 mg/L.

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).

Abstract

As an area bordering the Makassar Strait, Samboja Kuala District, most of the people make a living as fishermen. The fishing gear used by fishermen to catch shrimp and fish is a trawl. This study aims to identify the types of catches, determine the comparison of the percentage of main and by-catch at night. The method used in this study is a survey method, namely by going directly to the field. The main catches were 8 species of shrimp, namely Penaeus monodon, Penaeus sp, Penaeus merguiensis, Metapenaus affinis, Metapenaus monoceros, Metapenaeopsis palmenis, Metapenaeopsis barbata and Solenocera crassicornis. While the by-catch there are species of fish, cuttlefish and squid. The percentage of the main catch that was dominantly caught was Metapenaus affinis at 61% and the smallest was Penaeus sp 0%. While the percentage of by-catch is the most dominant fish beloso 33% and the smallest is grouper and bigeye fish 1% with a significance value <0.05 (sig. 0.24). The results of this study can show that there are differences in the main catch and by-catch in trawl fishing gear at night.
