Giant gourami (Osphronemus goramy) is one of the main freshwater fish of economic importance in Indonesia. Although this species has been reared for decades, particularly in the province of West Java, and naturally spawns in captivity, the availability of fry is still a limiting factor in aquaculture. Research efforts on giant gourami aquaculture are, however, limited and do not always address the difficulties encountered by fish farmers. The objectives of the present study were to provide the first description of giant gourami egg and fry production and highlight the main problems faced by farmers through targeted questionnaires and interviews. Our results show that the production of this species from eggs to juveniles is highly segmented, and there are currently no clear and standardized production methods. Farming practices vary greatly from one fish farmer to another. Climate factors (such as rain and temperature), proximity to urban areas, and the availability and quality of food are identified as the main limiting factors for egg and fry production. Based on a strengths, weaknesses, opportunities, threats analysis, we explore possible approaches to improve giant gourami aquaculture in Indonesia. The present study provides guidance for future research.

巨型古拉米(Osphronemus goramy)的鸡蛋和油炸食品生产调查:当前的饲养方法和对未来研究的建议

巨型古拉米(Osphronemus goramy)是印度尼西亚重要的重要淡水鱼之一。尽管该物种已经饲养了数十年,特别是在西爪哇省,并且自然地被圈养,但鱼苗的供应仍然是水产养殖的限制因素。然而,关于巨大的古拉米水产养殖的研究工作是有限的,并不总是能解决养鱼户所遇到的困难。本研究的目的是首先对巨型古拉米鸡蛋和鱼苗的生产进行描述,并通过有针对性的问卷调查和访谈突出农民面临的主要问题。我们的结果表明,该物种从卵到幼鱼的生产高度细分,目前还没有清晰,标准化的生产方法。从一个养鱼户到另一个养鱼户,养殖方式差异很大。气候因素(例如降雨和气温),靠近市区以及食物的可获得性和质量被确定为鸡蛋和鱼苗生产的主要限制因素。基于优势,劣势,机会,威胁分析,我们探索了改善印度尼西亚巨型古拉米水产养殖的可行方法。本研究为将来的研究提供指导。
