Published: February 2020

Abstract
The quality and quantity of Moina ephippia is influenced by the male and female sexual ratios in the population. The availability of males in the population can increase the number of fertilized eggs and ephippia hatching rates. This study aims to examine the concentration of rice bran suspension in culture to produce the most male offspring, and the quality and quantity of ephippia produced. Moina was cultured for twelve days and from the fifth day the feed is given with different concentrations. The results of this study indicate that, Moina culture using bran suspension feed with a concentration of 0.36-0.48 ml/L starting on the fifth day resulted in the production of low calf offspring but produced the highest total production of male offspring of 818±35 ind/L. Increased production of male offspring increases the production of ephippia containing two eggs but does not increase the degree of hatching significantly.

Published: February 2020

Abstract
The purpose of this research is having experience from around the world shows that fisheries management that produces lasting economic and ecological performance requires the use of fishing rights (rights-based fisheries management/RBFM) integrated as part of a well-designed management system that includes sustainable catch limits and effective monitoring and enforcement. The concept of fishing rights is not a new thing in Indonesia – in fact, many adat (traditional) customs such as sasi, awig-awig, and penglima laut are consistent with fishing rights and have been recognized for centuries. Such customary systems can provide a foundation for a new and effective system of fishing rights specially tailored to the culture, customs and needs of Indonesia. This research is using a qualitative method to identify what exactly happened in a coastal zone area. In reality, the concept of the Right to Management of Coastal Communities in the Regional Autonomy era has never been implemented in regional regulations that explicitly consider the rights needs of local communities. From the case of processing sea cucumber management permits in Sunsak Bay, East Lombok, it shows that local communities have never been a priority in the regional regulations to obtain the right to manage sea cucumbers.
