Abstract

The visual organ in fish has an important role in ensuring its survival. Fish can respond to bait or food with its visual organ. The objectives of this research are to analyse the visual performance of grouper (cone cell morphology, the visual axis, and visual acuity) and to analyse the relation between visual senses with fish behavior response to the bait. This research was conducted in the laboratory by means of the determination of fish retina histology method and behavior of fish. The morphology retina of grouper consists of a single cone and double cone which form a mosaic structure, the visual axis was identified at upper-fore with the angle of 26.8o.The visual acuity of grouper was low in index values with ranged from 0.06 to 0.07 for fish with a total length of 200 to 300 mm, the maximum sighting distance to the bait with the diameter of 20 mm size ranged from 3.93 to 4.74 m, the bait with 25 mm diameter size range from 4.91 to 5.92 and bait with a diameter of 30 mm size ranged from 5.89 to 7.11 m. The frequency of fish closed the bait distance of 30 cm was 45.83%, 25 cm was 33.33% and 20 cm was 20.83%, respectively.

UHT milk is a food commodity that plays an important role in fulfilling calcium nutritional sources. UHT milk consumption practices can be influenced by consumer nutritional knowledge. The general objective of this study was to analyze the relationship between nutritional knowledge and the characteristics of UHT milk consumers in Lamongan Regency and the relationship between nutritional knowledge and consumer nutritional attitudes. Sampling was carried out based on the calculation of the Slovin formula and obtained the number of 100 respondents. Data were analyzed descriptively and correlation test was performed. The results obtained as many as 77% of respondents have sufficient knowledge of nutrition. The nutritional attitude of the respondents showed that 63% of the respondents had adequate nutrition attitudes. The conclusion of this study is that there is a significant relationship between the education variable and the job characteristics of the respondents and their knowledge of nutrition. The test results of the relationship between nutritional knowledge and nutritional attitudes showed that there was a very significant and direct relationship between nutritional knowledge and nutritional attitudes
