Faecal moisture content can determine whether faeces appear soft or firm, and faecal character can influence whether owners are satisfied with a dog food. In a previous study, dogs appeared to produce softer faeces after noon. The purpose of the present study was to determine whether time of defecation affected canine faecal water content. A total of eight hound dogs were fed one of four canned diets as a single meal each morning for 1 week per diet in a Latin square design. All four diets contained approximately 77 % moisture and, on a DM basis, 24 MJ/kg gross energy, 23 % crude protein, 32 % crude fat, 31 % N-free extract and 1 % crude fibre. The proportion of dietary protein from soya-derived texturised vegetable protein (TVP):beef was 0:100, 14:86, 29:71 and 57:43, respectively. Soya carbohydrate partially replaced maize starch as TVP increased. Faeces were collected by direct catch during the sixth morning and afternoon of each diet period. Mean faecal moisture content was greater in the afternoon than in the morning (79 v. 71 %; P = 0·01) and increased with dietary TVP (P ≤ 0·0001), and there was an interaction between time of day and percentage TVP (P = 0·003). Faecal moisture content differed from morning to afternoon only with TVP in the diet. Faecal wet weight was similar from morning to afternoon. This suggests that time of day and presence of TVP from soya should be taken into account when evaluating the effect of a diet on faecal form and moisture content in dogs fed once daily.

Summary
In 1879, Congress established the U.S. Geological Survey (USGS) as a scientific research organization and charged it with conducting an “examination of the geological structure, mineral resources, and products of the national domain.” In 1962, these examinations were extended to the marine realm when Congress appropriated funds for offshore investigations by the USGS. On March 10, 1983, by proclamation of then-President Ronald Reagan, the United States claimed sovereign rights and jurisdiction within an Exclusive Economic Zone (EEZ). The United States assumed responsibility for the wise management of marine resources and for protection of the marine environment in the EEZ.
The EEZ of the United States is a vast frontier that extends seaward from 3 nautical miles to 200 nautical miles from the coast and brings within the national domain over 3.3 million square nautical miles of submarine lands, an area 30 percent larger than the total onshore area of the United States. With over 50 percent of this country's population clustered along our coasts, the adjacent ocean and ocean floor have become an integral part of the nation's land area to manage, use, and protect.
The rise of the United States to the status of a world power was made possible in part by exploitation of this country's natural resources. As a nation, we have never enjoyed full self-sufficiency in all raw materials that we require, and our growth has been accompanied by the often wasteful use of resources that many believed to be unlimited in quantity.
