The decline in vaname shrimp farming land in Lamongan Regency, East Java is influenced by the conversion of cultivation land into residential areas and industrial estate development so that it requires a breakthrough in aquaculture technology, one of which is by utilizing home garden for fish farming using tarpaulin ponds. This study aims to determine the feasibility of the cultivation of vaname shrimp in a circular pond with a recirculation system. The research method is an experimental method and qualitative descriptive in the cultivation of vaname shrimp in a circular pond with recirculation and non-recirculation systems. The results showed that the first pool showed better growth and survival of 10.1 gr / head and 76% with a total production value of Rp.2.470.000; while the second pool shows a lower growth and survival rate of 8.7 gr / head and 62% with a total production value of Rp. 1,620,000. Business feasibility has not been achieved in the first cycle because the value of small production is influenced by the growth of shrimp, low life graduation and lack of duration of maintenance, the simulation of business feasibility can be achieved in 3-4 maintenance cycles.
东爪哇拉蒙干县(Lamongan Regency)的虾田养殖面积减少是受耕地转为居民区和工业地产开发的影响，因此需要在养殖技术上取得突破，其中之一就是利用家庭花园利用篷布池进行养鱼。本研究旨在确定在循环系统的圆形池塘中养殖钒虾的可行性。本研究方法是采用实验方法和定性描述方法，对有循环水系统和无循环水系统的圆形池塘中虾的养殖进行研究。结果表明:第一池生长成活率较好，为10.1 gr /头，76%，总产值为2.47万rp;而第二池的生长和成活率较低，为8.7克/头，62%，总产值为162万卢比。第一个周期由于小生产的价值受虾的生长影响，寿命毕业度低，缺乏维护的持续时间，没有达到商业可行性，在3-4个维护周期中可以实现商业可行性的模拟。

The Success of kakatua fish catching (family scaridae) using very good handline was determined by bait. The type of bait that is always used by fishermen are crab and anchovy. The objectives of the study were 1) to determine the type of bait that faster to catch kakatua fish in large quantities, and 2) to determine the most effective time to catch kakatua fish in handline operation. Research activities were conducted in Watdek waters, Southeast Moluccas in March to May 2017. The catching operation is done simultaneously by two fisherman who use handlines above the speed boat. In one day 4 catching were made, between 06: 00-08: 00 am, 08: 00-10: 00 am, 14: 00-16: 00 pm, and 16: 00-18: 00 pm. This study used a comparative descriptive analysis method to analyze the difference time of kakatua fish catching. While statistical analysis of complete randomized design (RAL) was used to see the effect of bait type on the number of catches. The results showed that the crab bait obtained the highest, namely 318 fish or 70% and anchovy bait catch 135 fish or 30%. The best time to catch the kakatua fish (family scaridae) is at 06.00-08.00 am get 226 fish or 50%, 08.00-10.00 am gets 108 fish or (24%), at 16.00-18.00 pm gets 57 fish or (13%) and at 14.00- 16.00 pm gets 62 fish or 14%.

Gulamah fish bioecological research (Argyrosomus japonicas) in the estuary area of the coastal city of Merauke is very important to be done as a management effort. The purpose of the research on the bioecological of Gulamah fish in the estuary area of the coastal city of Merauke is to study aspects of population dynamics and reproductive biology aspects. The study was conducted in the Estuari area of the coastal city of Merauke for 3 months in November 2017 - January 2018. The research station was determined by purposive sampling. Gulamah fish growth patterns based on long and heavy relationship data are allometric negative. fish Gulamah males and females both at station I and station II also have relatively the same condition factor. The sex ratio between male and female Gulamah fish is 1: 1. Maturity level of gonad fish Gulamah caught during the research is still at TKG 1.
