Abstract

HighlightsThe Paku Uban (Nephrolepis biserrata) was identified and analyzedThe ability of paku uban to stimulated molting process of Scylla sp was analyzedThe paku uban (Nephrolepis biserrata) could increase the presentation of molting and accelerate molting processAbstractMud crab (Scylla spp.) is a fishery commodity with high economic value. For this reason, efforts to increase production are required with a more effective applicative technology. This study aims to determine the molting response and survival rate of mud crabs injected with paku uban leaf  extract (N. biserrata) at different doses. The study was conducted for 30 days, located in Tibi Island, Tanah Lia District, Tanah Tidung. The design used in this study was a completely randomized design (CRD) with five treatments and eight replicates. Mud crabs weighing 80 - 150 g were tested in K1 (without injection), K2 (controlled injection), P1 (100 ppm extract), P2 (125 ppm extract) and P3 (150 ppm extract). The effectivity of paku uban (N. biserrata) extract with the highest percentage of molting of 50% took place at P3, 37.5% at P2, and 25% at P1. The lowest levels of molting percentage were at K1 and K2 by 0%. The fastest molting period was ten days at P2, and the longest was 29 days at P1. The highest weight growth reached 33.75 g at P3, followed by P2 and P1 with 31 and 18.75 g, respectively. The survival rate of mud crabs for all treatments reached 100%. The results of the analysis of variance indicated a significant bet effect (P < 0.05) on the molting and weight growth percentage. The BNT test suggested that a dose of 150 ppm was the optimum treatment.

Abstract

HighlightThe sex ratio of giant prawns in the waters of fe- male groceries is 3 times higher than that of males.The growth characteristic of male and female   giant   prawns   is   negative   allometry, but the male and female body shapes are fat.Total   mortality, capture mortality, catch rate, male prawns are higher than females.The male infinitive growth is longer than the female,but the female's growth rate is faster than male.AbstractGiant prawns (Macrobrachium rosenbergii) is a crustacean class that has the larg- est size and its habitat in Sembakung waters included brackish water (estuarine) with a salinity variable of 6.5+0.5 ppt and a temperature variable of 28.5+0.5OC and a variable pH of 6 (acidic). The objective of this research was to analyze the growth and mortality model of giant prawns (M. rosenbergii) that was taken from the catch of fisherman in the estuary, Sembakung sub-district, Nunukan Regency, Indonesia. The study was conducted for 3 months from November 2019 to Janu- ary 2020. The sampling was by using a survey method with purposive judgment sampling based on a catch of 14 fishermen who used the bottom fish pot from Sembakung waters, Nunukan Regency (Indonesia). The data collection included data of sex, total length, and the total weight of giant prawns. While analysis was employed for growth pattern, condition index, Von Bertalanffy growth, and mor- tality. The results obtain the sex ratio of male and female giant prawns 1:3.67. The growth pattern of male and female giant prawns were allometric negative. The growth of the von Bertalanffy model for infinitive growth of male giant prawns were 21.219 cm and female were 18.42 cm, respectively the mortality from giant prawns obtain total male mortality is 2,257, catch mortality is 1.92 and natural mortality is 33.75% with an exploitation rate of 0.85 (85%). The total female mor- tality is 1.528, catch mortality is 120.1% and natural mortality is 32.69% with an exploitation rate of 0.786 (78.6%).
