Abstract

Fish need a specific environment as a habitat to grow and develop. Environmental conditions can change, so this becomes a challenge for fish to maintain homeostasis in the fish's body. Two factors influence the physiological condition of fish, namely internal and external factors. Information regarding fish physiology is needed as one of the factors that are the centre of attention in proper cultivation to support the productivity of commercial fish cultivation. Environmental changes such as pollution significantly affect the physiological condition of fish, and supplementing fish food can also support the fish's body metabolism. This article review study describes important factors that can influence the physiological response of fish and provides three case studies of commercially farmed fish when exposed to toxic substances or the provision of organic substances in feed. The data used is secondary data using journals from previous research and grouping topics regarding environmental factors and case studies on grouper fish in the Serranidae family.

Abstract

Caulerpa sp. is a type of sea grape from the green algae group that can be used as food. In Indonesia there are still very few people who can cultivate it and its current availability comes from harvesting it in nature. The aim of this research was to analyze the effect of different seed weights on the growth and antioxidant content of Caulerpa sp. cultivated using the basic stake method. The research was carried out in Rompo Village, Langgudu District, Bima Regency. Cultivation of Caulerpa sp. carried out for 30 days. The research used the Completely Randomized Design (CRD) method which consisted of 5 treatments, namely; A : 100 grams (20 g / 5 points), B : 125 grams (25 g / 5 points), C : 150 grams (30 g / 5 points), D : 175 grams (35 g / 5 points), and E : 200 grams (40 g / 5 points). The research results explained that the highest absolute growth was in treatment E (69.8 grams). The highest specific growth was in treatment A (1.395% / day). Number of dots of Caulerpa sp. The most were found in treatment E (414 dots). Antioxidant value of Caulerpa sp. The highest was in treatment A (87.15%). The conclusion of this research is that different seed weights have an influence on absolute, relative growth, number of dots and antioxidant content. A seedling weight of 200 grams (Treatment E) gave the best absolute growth and increase in the number of dots, namely 69.8 grams and 414 dots. A seed weight of 100 grams (A) provides the best specific growth and amount of antioxidants, namely 1.395% / day and 87.15%.
