Abstract

This study aims to determine the effect of carrot extract on the phagocyte activity of Vibrio alginolyticus in white snapper. This study used a completely randomized design (CRD) with 4 treatments and 3 replications. The treatments used respectively as follows, treatment A: 0 µl extract/individu, B: 100 µl extract/individu, C: 150 μl extract/individu, and D: 200 μl extract/individu. The average value of phagocytic activity tended to increase, namely treatment A 8.67%; treatment B 9.33%; treatment C 11.00%; and treatment D 14.00%. Carrot extract can increase phagocytic activity of white snapper. An effective dose that can increase the immune response of white snapper was 200 µl extract/individu of fish.

Abstract

This study aimed to determine the effect of vitamin C enrichment on fresh trash feed on the growth of Asian seabass (L. calcarifer) and their optimal dosage. The study used a completely randomized design with 4 treatments and 5 replications for each treatment. The treatment given was a dose of vitamin C 3.5 g / kg of fresh trash feed (A); dose of vitamin C 4 g / kg fresh trash feed (B); dose of vitamin C 4.5 g / kg fresh trash feed (C); and fresh trash feed without vitamins (D). Enrichment of vitamin C in fresh trash feed significantly affected the absolute growth of Asian seabass. Treatment A, 17,60; treatment B, 19.79; treatment C, 17.11; and treatment D 13.32 g. Enrichment of vitamin C in fresh trash feed also significantly affected the specific growth of Asian seabass. Treatment A, 2.41%; treatment B, 2.60%; treatment C, 2.37%; and treatment D 2.04%. Enrichment of vitamin C in fresh trash feed did not significantly affect the survival of Asian seabass. Treatment A, 42.5%; treatment B, 47.5%; treatment C, 45%; and 40% D treatment

Abstract

Kappaphycus alvarezii seaweed is one of the main commodities of aquaculture which is economically important and has been cultivated commercially. In the Kappaphycus alvarezii seaweed cultivation system, the attack of ice-ice is a major obstacle because it can harm the cultivation business. The spread of the disease can occur vertically and horizontally. This study aimed to observe the horizontal transmission rate of ice-ice disease in cultivation activities of K. alvarezii in Maba Waters, East Halmahera Regency. The results showed that the attack of ice-ice caused a decrease in growth and experienced death. The presence of this disease in seaweed cultivation can result in a decrease in seaweed production. This is a major problem faced by K. alvarezii seaweed cultivation managers and requires serious handling with proper management

Abstract

The problem of pollution that occurs in the aquatic environment is getting out of control and causes the degradation of fishery resources which are important for humans. One of the pollutants from industrial activities is heavy metal. There are various kinds of heavy metals, mercury (Hg) is the most dangerous heavy metal. Mercury (Hg) enters directly into the waters through rainwater and leaching the soil and river flows which are then absorbed and metabolized by microorganisms. Mercury (Hg) is difficult to degrade from the body, because mercury (Hg) is actively involved in the food chain. Microorganisms feed molluscs, crustaceans and fish which are a source of protein for humans. Mercury (Hg) toxicity in fish can result in a stress response in fish which results in impaired growth, immune system, and changes in tissue structure. This brief review aimed to enrich the scientific repertoire of the toxicity of mercury (Hg) in fish and its effects on humans. This review was a non-experimental research by conducting research around the literature

Abstract

The development and progress in the mining industry has created an opportunity for the concentration of heavy metals to increase uncontrolled in waters and lead to degradation of fishery resources. Heavy metals are one of the pollutants from industrial activities that enter directly into the waters through rainwater and soil washing and river flows which are then absorbed and metabolized by microorganisms. Heavy metals are difficult to degrade and are actively involved in the food chain. Microorganisms feed molluscs, crustaceans and fish which are a source of protein for humans. Nickel metal (Ni) is a metal that can cause a stress response in fish which results in impaired growth, immune system, and changes in tissue structure. This brief review aims to enrich the scientific repertoire of nickel (Ni) metal contamination in fish and its impact on humans. This review is a non-experimental research by conducting research around the literature
