Abstract
Lead toxicity in humans causes neurological disorders, bone metabolism disorders, kidney damage, and impaired liver function. Feather shells that live in marine waters with high Pb heavy metal content can be exposed to these heavy metals, posing a risk to humans who eat shellfish. Depuration is one method that can reduce the Pb content in the body of the feather shell. The depuration process is influenced by several factors, including the length of the depuration and the filter used. This study aims to determine the effective depuration time to reduce the Pb content in feather shells (Anadara antiquata) using zeolite as a filter. This study applied the Latin Square Design (RSBL) method as a research design consisting of four treatments with four replications. The duration of the depuration treatment was 0 hours (P0), 24 hours (P1), 48 hours (P2), and 72 hours (P3). The effectiveness of the depuration of shells using a zeolite filter can be seen in the reduced Pb content in shellfish. The depuration process for 24 hours showed an effective depuration time with a reduction rate of Pb of 1.095 ± 0.05 mg/kg.

Abstract
Selection programs for giant freshwater prawns stocks from various locations have been implemented by several government institutions. Some of the results of selective breeding of giant freshwater prawns have been released by the Indonesian Ministry of Marine Affairs and Fisheries. Several giant prawn strains have been released, including GIMacro, GIMacro II, and Siratu. The development of giant prawn strains after release has not been significantly observed among shrimp farmers. Therefore, it is necessary to evaluate its productivity in order to observe its impact on the development of giant prawn aquaculture. The study was conducted using a meta-analysis method with data sources derived from searching the database on Google.com. The result s of this study indicate that selective breeding of giant prawn can successfully increase the productivity of their farming (P< 0.001). It has also been demonstrated that the effectiveness of family selection significantly accelerates the growth rate of giant prawns. It is anticipated that the findings of this study will help formulate policy solutions for reversing the current drop in giant prawn production.
