“…L-Ascorbic acid (AA) was the only source of vitamin C traditionally used in shrimp feed. However, AA is unstable and feed has been shown to lose ascorbic acid during processing and storage due to exposure to high temperature, oxygen and light [3][4][5]. Shiau & Hsu [6] found that about 75% of the initial amount of supplemented AA in shrimp feeds can be lost during processing at ambient temperature.…”

“…[3][4][5] Because of its instability, ascorbic acid averaging several times the recognized dietary requirements are commonly added to fish feeds to ensure adequate levels at ingestion. This is why several ascorbic acid derivatives have been tested for their biological activity as a vitamin C source.…”

L-ascorbic acid (C1), L-ascorbyl-2-sulfate (C 2), and L-ascorbyl-2-monophosphate (C3-M) were each incorporated into a laboratory -made P . monodon diet. Diets were extracted by deionized water or by 5% meta-phosphoric acid and then subjected to standing for 0 , 10, 20, 30, 40, 50, and 60min before high performance liquid chromatography (HPLC) analysis. Results indicated that the laboratory diet -making process destroyed about 67-75% of C1 and 21-24% of both C2 and C3-M . C2 and C3-M were stable before the analysis after either the water or meta-phosphoric acid extraction . On the other hand, a steady decline of 27. 8, 41.1, 62.6, 73.9, 81.7, and 85 .7% in C1 activity was found when extracted by water and allowed to stand for 10 , 20, 30, 40, 50, and 60min, respectively, before the HPLC analysis.

“…In that the level of this nutrient also declines markedly during embryonic development in fish (Sato et al, 1987), tissue levels need to be rapidly restored during early feeding (Soliman et al, 1986). While the PC diet contains vitamin C, oxidation during processing and storage as well as leaching (Goldblatt et al, 1979;Soliman et al, 1987) of this vitamin could reduce levels reaching the early feeding period. Because vitamin C is particularly important to fish growth and reproduction, as well as various aspects of detoxification (see reviews by Hilton, 1984;Lovell, 1984;Sandnes, 1984), establishment of adequate tissue levels should be undertaken.…”

This research has been conducted both in-house and extramurally and has involved scientists from other Federal agencies, academic institutions, and the private sector. The need to enhance the integration of the research became increasingly evident as the program grew in the late 1980's. This growth came principally as a result of the U.S. Army Corps of Engineers sponsorship of research to develop environmental applications of new, in vivo hazard assessment models for use in the burgeoning Department of Defense environmental remediation program. One of the many uses of these models is to answer the question, "How clean is clean?" and to assist in the establishment of more realistic clean-up goals for hazardous waste sites.An annual research review meeting was undertaken to facilitate the integration and technology transfer of this research program. This publication is the second 14. SUBJECT TERMS Fish, Medaka, Irout, #13.(Continuation) compendium of these meetings.The papers contained in this document are meant to provide the program management staff with an additional means of reviewing the status and progress of extramural and selected in-house studies in the area of new toxicity assessment models. The papers are, therefore, the principal investigators' (PIs') best efforts to characterize the research at the time of the meeting.Some papers cover the results of several years of research and others outline only the planned research of a new project. The data presented and conclusions of the authors represent the best professional judgment of the respective PI at the time of the workshop but are not equivalent to a peer-reviewed report of completed research.
