Mones AB, Harms CA, Stoskopf MK. Implications of comparative ventral body wall histology on selection of abdominal surgical approach and closure in 12 species of fish. JOURNAL OF FISH BIOLOGY 2021; 98:1342-1348. [PMID: 33411333 DOI: 10.1111/jfb.14668] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/28/2020] [Revised: 12/19/2020] [Accepted: 01/04/2021] [Indexed: 06/12/2023]
Abstract
A ventral midline surgical approach for fish celiotomy is commonly performed in veterinary clinical medicine and research, although the relevant ventral body wall anatomy of many fish species is not well documented. Histological evaluation of tissue samples from the ventral body wall of 12 fish species was performed to provide a reference for surgical approach and closure decisions. The width between muscle bundles running parallel to the long axis and total thickness of tissue layers varied among species. An appreciable space between longitudinal muscles of the ventral body wall and a lack of muscle, vessels and nerves on midline in all species examined supports recommendations of ventral midline incisions to spare important structures. Dense connective tissue consistent with an aponeurosis between musculature along the ventral body wall was not observed in any species evaluated. Connective tissue was concentrated within the dermis of all species evaluated, with an additional layer of collagen along the coelomic membrane in Russian sturgeon Acipenser gueldenstaedtii, koi Cyprinus carpio, goldfish Carassius auratus, black drum Pogonias cromis, black seabass Centropristis striata, tomtate Haemulon aurolineatum and scup Stenotomus caprinus. A sufficiently wide space on ventral midline for practical targeting during the surgical approach is present in A. gueldenstaedtii, C. carpio, striped bass Morone saxatilis, H. aurolineatum, P. cromis, rainbow trout Oncorhynchus mykiss and brown trout Salmo trutta. Sand perch Diplectrum formosum, C. auratus, S. caprinus, grey triggerfish Balistes capriscus and black sea bass Centropristis striata have a negligible space between longitudinal muscles on midline. The variation in ventral body wall structure observed in this study helps inform surgical decision making for celiotomy incision and closure in these species.

Histological and immunohistochemical characterization of 17 gonadal tumours in koi carp (Cyprinus carpio koi). JOURNAL OF FISH DISEASES 2021; 44:273-285.

Abstract
Reports on abdominal tumours in koi carp are scarce and most are from the gonads. Their histological diagnosis is challenging due to the occurrence of mixed populations of neoplastic cells and the few availability of cross-reactive antibodies in fish tissues. The present study aims to provide a histopathological characterization of seventeen gonadal tumours, enriched by a wide antibody panel (vimentin, CD117, placental alkaline phosphatase-PLAP, AE1/AE3 cytokeratin, E-cadherin, proliferating cell nuclear antigen-PCNA, müllerian-inhibiting substance-MIS, GATA4 and Inhibin-α) applied on whole and tissue microarray (TMA) sections. Abdominal enlargement was associated with tumours filling 30%-80% of the abdominal cavity; frequently, the gonads had been completely replaced by neoplastic tissue. Twelve cases were characterized as sex cord-stromal tumours (SCSTs), three as germ cell tumours (GCTs), one as mixed germ cell sex cord-stromal tumour (MGCSCST) and one as carcinoma. By immunohistochemistry, PLAP enabled confirmation of GCTs, ovarian carcinoma and the objective identification of a further cell component in 8 out of the 12 SCSTs that were reclassified as mixed tumours. The use of an immunohistochemical panel can help in refining the histological diagnosis, but the morphological diagnosis still represents the main tool for the characterization of these tumours in koi carp.

Abstract
Gonad abnormalities can restrict or completely block reproductive capability of individuals and in some case that of their populations. Here, we describe a novel testicular degenerative condition of non-germ cell origin with a high prevalence (up to 22.1% of the population) in a wild population of carp. Based on gross morphology, and microscopic and cellular examinations, the condition shows progressive severity which could be categorized into low, mild, severe and complete. In early stages of the condition, an abnormally increased proliferation (11-fold) of the Sertoli cell occurred, followed by degenerative cell death of all testicular cells, resulting in fluid-filled vesicles in the later stages. This initial uncontrolled proliferation of Sertoli cells suggests that the condition could be triggered by malignant pathways; however, the observed subsequent apoptosis of all testicular cells en masse, rendering the animals "sterile," appears unique. Observations, to date, indicate that this condition is specific to male carp and not present in other species of fish sharing the habitat. High prevalence of the condition allowed comparative evaluation between affected individuals, an aspect likely to facilitate future studies, including elucidation of the cause, robust testing of therapies and practical applications such as management of feral carp populations.

Abstract
The scientific literature contains a wealth of information concerning spontaneous fish neoplasms, although ornamental fish oncology is still in its infancy. The occurrence of fish neoplasms has often been associated with oncogenic viruses and environmental insults, making them useful markers for environmental contaminants. The use of fish, including zebrafish, as models of human carcinogenesis has been developed and knowledge gained from these models may also be applied to ornamental fish, although more studies are required. This review summarizes information available about fish oncology pertaining to veterinary clinicians.

Abstract
Because anesthesia of amphibian larvae is currently problematic, the aim of this study was to test if a fish anesthetic containing approximately 500 g/L isoeugenol (Aqui-S) could anesthetize tadpoles. Three concentrations of Aqui-S were tested (of commercial solution 10, 20, and 50 microl/L) with 10 tadpoles of the southern brown tree frog (Litoria ewingii) per concentration. Tadpoles were anesthetized for 15 min in water at 18-20 degrees C. Anesthetic criteria included four time points and two heart rates: time to loss of response to stimulation, loss of righting reflex, and return of spontaneous movement and of righting reflex after removal from Aqui-S, and heart rate after induction and after 15 min of anesthesia. No tadpole showed signs of irritation or excitement, no tadpole died, and all returned to normal behavior. The times for induction of anesthesia (time to loss of righting reflex) decreased significantly (P < 0.001) with increasing concentration: means of 27.5, 16.8, and 5.7 min for 10, 20, and 50 microl/L, respectively. Heart rate after 15 min of anesthesia was significantly lower (P = 0.006) for concentrations of 20 and 50 microl/L compared to 10 microl/L. At the lowest concentration (10 microl/L), anesthesia was light. Recovery times were significantly delayed (P < 0.001) for 50 microl/L, approximately double those for the lower concentrations. Spontaneous movements began at 56.9, 51.4, and 119 min for 10, 20, and 50 microl/L Aqui-S, respectively. Although Aqui-S did anesthetize tadpoles at all three concentrations, with 20 microl/L being the most suitable, additional longer-term toxicity testing is required prior to its adoption as an anesthetic agent for this species. Anesthesia, isoeugenol, Litoria ewingii, southern brown tree frog, tadpoles.
