Anxiety is believed to be an important psychological dimension in determining the outcome of sport matches. However, studies examining this aspect of Papuan elite athletes have never been conducted. Therefor, this study aims to reveal the differences in the anxiety amidst the Papuan elite athletes in terms of sport and gender. Furthermore, the comparative research method used involves six sports with different characteristics, namely game, martial arts, and accuracy. Subsequently, a total of 100 athletes in the PON XX preparation training camp are involved, with about 39 in the game (M= 19, F= 20), 32 in martial arts (M= 18, F= 14), and 31 in the accuracy sport (L = 14 P = 17). Furthermore, the Sport Anxiety Scale-2 (SAS-2) is used as an instrument for data collection on athlete's anxiety. Research data collection is carried out during the COVID-19 pandemic, so that the distribution of research instruments is carried out online using the google form.

However, the use of copepod for fish hatchery in Indonesia has not developed yet, it is related to the constrain on copepod mass culture. The species of Copepod that has been widely used is Acartia spp.. The objective of this study was to determine the formulated diet for Acartia spp. mass culture. Four formulated diets were the combination of three materials i.e. i.e. fish meal, PSP meal and krill meal. The diets were applied in 1500 L mass culture. The finding of this study emphasize that feed formula PS-P + krill (TR) is considered as the promising feed for Acartia spp mass culture. This finding also indicates that in the incoming time it is crucial to develop copepods feed to boost copepods production by including marine algae that exclusively produce Omega-3 fatty acid EPA and DHA, the nutrients play a vital role in copepods reproduction and growth
