Histological Observation Of Milkfish Organs With Stunting Phenomenon

Milkfish (Chanos chanos) is an important economic fish. Milkfish is widely consumed because it has high nutritional value. Milkfish is also used as live bait for fishing. In the milkfish cultivation system, increasing production is a very important factor. One of the efforts to increase production in fish farming systems is the application of high stocking density. Constraints to the application of the high stocking density cause the growth of milkfish to be non-uniform, some of them even experience stunting, which is a condition in which the fish experience slow growth. This study aims to observe the condition of the milkfish tissue with normal growth and stunted fish. Milkfish (Chanos chanos) used are fish that have been reared for 6 months. Fish organs that were sampled for observation were stunted and normal (non-stunting) fish. The organs observed were the gills, muscles, and intestines. The results showed that stunted milkfish (Chanos chanos) affected the condition of the gill tissue, muscles, and intestines. The gills are edema and necrosis. Muscles undergo edema, degeneration of muscle fibers, and necrosis. The intestine experiences necrosis or cell death.Keywords: Milkfish; Stunting; Histology.AbstrakIkan Bandeng (Chanos chanos) merupakan ikan bernilai ekonomis penting.

The trials of seaweed Caulerpa racemosa cultivation using the off-bottom culture at The Kastela Waters, Ternate Island Districht, Ternate City

Seaweed of Caulerpa racemosa  has bright prospects for cultivation. In North Maluku province in general, the cultivation of seaweed Caulerpa sp has never been developed, even though the waters of North Maluku have enormous potential, because this type of seaweed is scattered in various marine waters in North Maluku. One of the efforts that needs to be done is to carry out this type of seaweed cultivation in an optimal and sustainable manner.The seaweed Caulerpa racemosa cultivation unit used in this study was the off-bottom method measuring 5 m x 10 m. This size can contain 5 stretch ropes/risers with a length of 10 m and a distance of 1 m between the stretch ropes/risers. Each stretch / riser line contains about 45 seed clump points with a distance between clumps of 15 cm. The observation procedure for the growth of Caulerpa racemosa seaweed was carried out by weighing the seaweed seeds in each stretch/riser rope. The weight of seed that is weighed is the weight of seeds at the time of planting and the weight of seaweed at harvest.The results showed that the average growth rate of  seaweed Caulerpa racemosa was varied for each rope. In ris 1 rope, the average absolute weight growth reached 100.88 grams, ropes 113.33 grams, ris rope 3, 88.00 grams, rope ris 4, 116.00 grams, and rope ris 5, amounting to 113, 33 grams. In general, the highest growth in absolute weight was found in the fourth rope, which was 116.00 grams
