Abstract

Endoscopic techniques for visceral organ and ovarian examination of rainbow trout (Salmo gairdneri) are described. Internal organs can be readily identified and qualitatively assessed. It is possible to distinguish sex, and in the female, state of maturity can be identified, as well as some morphological characteristics of individual ova. Repeated use of the initial entry hole for the endoscope is recommended. Gross healing of the surgical incision is 70% complete in 7–10 days, without signs of inflammation or other internal damage. The advantages of fine needle fibre endoscopy are discussed.

    Endoscopic evaluation of the coelomic cavity showed the following advantages: reduced invasiveness, direct visualization and magnification of the target organs, and quick uneventful recoveries. Furthermore, the small incision required for the endoscopic technique has reduced risks of tissue adhesions and dehiscence of incision sites, which often result in coeliotomies.4-8,21 Coelioscopy allows clinicians to have direct visualization of the target organs and to collect diagnostic samples, thus improving the clinician’s diagnostic capabilities using a relatively noninvasive method.

    To minimize the latter problem, we allowed 2 days for evacuation of the intestinal tract before applying our method. Regardless, the effectiveness evident in our results support other studies that have found endoscopy to be a useful technique for determining maturity status and sex of mature fish (Moccia et al., 1984; Ortenburger et al., 1996; Bryan et al., 2007; Wildhaber et al., 2005, 2007; Hurvitz et al., 2007). Our results further indicate that use of endoscopy can be effective for sturgeon that mature at relatively small sizes and earlier ages which we had fish with 7 kg weight as the smallest fish in present study.
